We'll also discuss non-GAAP financial measures, and all results exclude special items unless otherwise noted. You can find a reconciliation of our non-GAAP measures on the Investor Relations page at ir.delta.com.
With that, I'll turn the call over to Ed.
Ed Bastian
Thank you, Julie. Good morning everyone.
We appreciate you joining us today. This morning, we reported our June quarter results, and it's clear that Delta's brand and industry position are stronger than ever.
We generated record revenue, which grew 14%, increasing more than $2 billion over last year. This reflects sustained strength in demand and momentum across our diversified business.
We delivered pre-tax profits of $1.4 billion, earnings of $1.56 per share, and an operating margin of 9%, all better than the guidance that we provided at the start of the quarter. Return on invested capital was 11%, well above our cost of capital.
Through the first half, we've generated $1.4 billion of free cash flow, fortified our investment-grade balance sheet, and announced a 15% increase to the dividend. Most importantly, we kept investing to make travel safer, easier, and more enjoyable for our customers.
Our people are what truly set Delta apart. Their efforts delivered industry-leading performance across key operational metrics, and also earned Delta recognition from The Points Guy as the best U.S.
airline for the eighth consecutive year. Our people are our number one competitive advantage, and I want to thank the Delta team for their commitment to delivering for our customers every day, particularly during the busy summer travel season.
In May, we announced a 4% pay increase, and we've accrued nearly $500 million towards next year's profit-sharing payout through the first half of the year. Both reflect our longstanding commitment to sharing success with the people who drive it.
Turning to the current environment, the U.S. economy remains resilient, supported by strong employment, rising household incomes, and significant wealth accumulation.
Our customers are prioritizing experiences and investing in the moments and connections that matter most to them, driving sustained strength in demand for air travel. These trends align well with Delta's strategy, demonstrating the loyalty that we are seeing across customer segments, and powering high-margin diverse revenue streams that enhance the resilience of our business.
Our Delta American Express partnership is a clear example of the strength of our loyalty ecosystem. Card spend has grown double digits for the past seven quarters, with particular strength among our premium Reserve cardholders.
With continued momentum in both new card acquisitions and spend, we expect remuneration of $9 billion this year, up 10% over 2025. As I stated in April, high fuel prices have proven to be the most powerful catalyst for change in our industry, and this year that has once again been the case.
Coming into the recent fuel spike, most U.S. carriers were already struggling to earn their cost of capital against a backdrop where industry airfares had meaningfully trailed inflation, costs have reset higher, and consumer preferences have evolved.
As we predicted, structural change has accelerated, enabling the industry to recapture this year's fuel cost inflation at the fastest pace of any recent cycle. Even after recent fare increases, airfares remain 10% to 15% points below overall inflation since COVID.
With continued fuel volatility and much of the industry still earning returns below its cost of capital, we believe current revenue momentum should remain sustainable even if fuel prices moderate. That is an important step towards improving the industry's financial health and earning sustainable returns over time.
For Delta, we are executing on our strategy from a position of strength, and with continued revenue momentum, measured capacity, and a more stable fuel environment, we expect to return to earnings growth on double-digit operating margins in the second half of this year. For the full year, we are affirming the guidance that we set at the start of the year even with a multi-billion-dollar fuel headwind.
Our outlook for earnings of $6.50 to $7.50 per share represents growth of 20% year-over-year, and our free cash flow outlook of $3 to $4 billion brings our three-year cumulative total to over $11 billion. Looking beyond 2026, we are confident in our long-term financial framework and path to mid-teens margins and return on invested capital.
The strength and consistency of our results give us the ability to keep investing and innovating to extend Delta's lead, elevating the experience and creating a more seamless and personalized travel journey. As we invest in the areas that customers value the most, loyalty to Delta continues to grow.
Last month, we opened our second Delta One Lounge at LAX, bringing the Delta One Lounge network to five locations and expanding the industry's largest club and lounge footprint. Our Delta Amex co-brand card continues to lead the industry, and our recent portfolio enhancements are strengthening the value proposition for both existing and prospective cardholders.
We are also making the journey more seamless through Delta Concierge, our AI-powered digital assistant, which is now available to more than half of Fly Delta app users, with a full rollout later this month. In the air, we continue to set the standard on connectivity.
Fast, free Wi-Fi is already available to members across nearly our entire fleet, with satellite upgrades coming online in the months ahead to deliver even faster speeds and broader global coverage. Starting in '28, Amazon LEO will unlock the next generation of onboard connectivity, reach, and personalization.
In closing, our performance and outlook reinforce the durability and the differentiation of the Delta business model and our investment thesis. Looking ahead, I am incredibly optimistic about Delta's future and our opportunities to deliver even better performance for our employees, our customers, and our owners.
Now Dan will cover off on our operational results.
Dan Janki
Thank you, Ed, and I want to begin by thanking the Delta team for the outstanding service they provide our customers every day. Operational excellence is core to the Delta brand, and it's the experience our customers expect.
Our culture of continuous improvement, that spirit of keep climbing, drives us to get better every day. This, combined with the continued investment in technology and data, better position our people to run a great operation, improving reliability and efficiency.
During the quarter, we extended our industry leadership in on-time arrival and departure performance, while strengthening operational metrics across our system. Completion factor improved through the quarter.
We expect continued progress into the second half as targeted actions we have taken to improve resilience gain further traction. We delivered record baggage performance, led by our largest hub in Atlanta, where performance has improved meaningfully from last year's strong baseline, supported by enhancements to our baggage handling system and processes, and our patented baggage AI technology.
Delta's continued to lead large U.S. carriers in domestic Net Promoter Scores, improving over last year.
This was driven by outstanding service of the Delta team, with people interaction scores reaching all-time records across this global system. This includes year-over-year improvement across airport customer service, reservations and care, flight attendants, and our pilots.
This performance reflects the focus of our people, reinforces how we're making travel easier and more reliable to every customer. We are continuing to invest in technology while empowering our people to deliver more proactive communication directly to customers.
We're also enhancing digital tools with a simplified rebooking process, expanded self-service, and continued rollout of Delta Concierge. Our customers are noticing.
This has driven more than 25-point improvement in NPS during periods of irregular operations. A more reliable customer experience starts with a more reliable fleet, and our Delta TechOps team is central to that.
Key fleet reliability metrics, including aircraft out-of-service levels, maintenance-related delays, and cancellations all improved versus prior year, benefiting from predictive maintenance capabilities and the investments we've made in fleet resilience over the last few years. Beyond supporting our own operation, the TechOps represents an exciting operation to further diversify our revenue through growing our third-party MRO business.
This year, we remain on track to generate approximately $1.2 billion in revenue, up nearly 50% from last year, with low-double-digit margins. Over the next several years, our technical capabilities, coupled with our strong customer relationships and record backlog position us to more than double MRO revenue while expanding margins.
Now I'll turn it over to Joe to cover our commercial results and outlook.
Joe Esposito
Thank you, Dan. June quarter results reflect strong execution and our clear prioritization of managing for margins.
Total revenue of $17.7 billion was at the high end of our expectations, up 14% over prior year on approximately 1% capacity growth, driving total unit revenue growth of 12.4%. We are focused on continuing this revenue momentum to fully recover this year's fuel cost pressure and improve margins as we move through the back half of the year.
Domestic led unit revenue growth, up 12.4%, driven by higher yield, with international growing 8% over prior year, led by Latin. Importantly, main cabin trends improved through the quarter, with main cabin unit revenue growing mid-teens in the month of June.
Across corporate sales, all sectors posted double-digit growth. Performance was strong across core and coastal hubs, where sales rose more than 20% versus prior year.
Diverse revenue streams represented 61% of total revenue in the quarter, up 2 points over last year, with premium and loyalty revenue both up nearly 20%. Cargo revenue grew 39%, primarily on volume, and MRO delivered revenue growth of more than 30% year-over-year, driven by legacy engine platforms.
Now turning to outlook. Demand remained strong and broad-based.
Cash sales improved through the quarter across the entire booking curve in both premium and main cabin products. These trends, combined with our measured approach to capacity growth, support the sustainability of yield strength.
We accept September quarter revenue to grow mid-teens versus last year. Total unit revenue growth is expected to improve sequentially, even against more challenging prior-year comparisons.
While it remains early, December quarter bookings are coming in strong, giving us confidence that this revenue strength will extend through the fourth quarter. Capacity for the third quarter is up 1%, while fourth quarter planned 2% to 3%, led by international.
Our integrated commercial strategy is how we will continue to deliver a revenue and margin premium to the industry. We are expanding our global network through new routes and JV partnerships, while continuing to renew our fleet, enabling us to grow the network more profitably.
We are also improving the product and giving customers more choice. The rollout of Basic, Classic, and Extra offerings in Delta Comfort is now complete, and will be expanded across all premium cabins this quarter.
These offerings increase flexibility for customers, while driving improved revenue performance. Loyalty remains one of Delta's most valuable assets.
SkyMiles membership growth is outpacing capacity, led by double-digit gains among Gen Z members. That engagement is translating into durable revenue, best illustrated by our industry-leading co-brand performance.
In closing, these investments reinforce our competitive advantage and give us more ways to grow revenue, deepen loyalty, and expand margins over time. I'll now hand it to Erik to discuss our financial performance.
Erik Snell
Thank you, Joe. I want to start by recognizing the Delta team for delivering strong 2Q results.
We generated $1.4 billion of pre-tax profit, with an 8.8% operating margin, despite the highest fuel costs in our history, reflecting the structural advantages we built in the business. Total fuel expense was $4.4 billion, up nearly $2 billion versus last year.
Fuel price per gallon averaged $3.93, including an 11-cent refinery benefit, net of a 5-cent impact from a temporary outage. Fuel price came in better than guidance, as lower crack spreads more than offset the reduced refinery benefit.
The refinery is a strategic advantage for Delta, providing a meaningful offset in a high-crack environment, and we expect 2026 to be one of its most profitable years. Non-fuel unit costs increased 6.8% over prior year in the June quarter, reflecting higher crew and revenue-related costs on capacity growth several points below our initial plan.
Through the first half, we generated $4 billion of operating cash flow and $1.4 billion of free cash flow after $2.6 billion of reinvestment. Investments we are making are further compounding our advantages.
The durability of our performance allows us to invest year after year in our employees and in elevating the customer experience, all while continuing to pay down debt. Our balance sheet is the best in Delta's history, with investment-grade ratings from all three major credit agencies and a substantial and growing base of unencumbered assets and secured borrowing capacity.
We ended the quarter with adjusted net debt of $13.6 billion, down from year-end, while much of the industry raised additional capital. Debt reduction remains a top priority, and we expect gross leverage to reach 2 times by year-end.
As we move toward our long-term target of 1 times, we remain committed to increasing shareholder returns. Turning to our outlook, we expect September quarter non-fuel unit cost performance to improve modestly, with further progress in the December quarter as operational investments continue to gain traction and capacity growth begins to normalize.
This puts us back on a path toward our long-term framework of low-single-digit unit cost growth. Our outlook assumes an all-in fuel price of approximately $3.15 per gallon, including a 5-cent refinery benefit.
Total fuel expense is expected to be about 40% higher than last year. Combined with our mid-teens revenue growth outlook, we expect a 3Q operating margin of 11% to 13%, and earnings per share of $2 to $2.50 $2.50, up meaningfully from $1.70 last year.
In closing, the affirmation of our full-year outlook from the start of the year and ability to grow earnings despite a nearly $4 billion increase in fuel cost reinforces that Delta's durability continues to improve relative to prior cycles and to the industry. Delta's differentiated strategy and consistent execution across dynamic environments give us confidence in delivering our long-term financial framework and creating sustained value for our owners.
We will now move to Q&A. Julie, please open the line for analyst questions.
Julie Stewart
Matthew, can you please remind the analysts how to enter the call queue?
Operator
Certainly. At this time, we'll be conducting a question-and-answer session.
If you have any questions or comments, please press *1 on your phone at this time. We do ask that while posing your question, please pick up your handset if you're listening on speakerphone to provide optimum sound quality.
We do ask that all Q&A participants please limit to one question and one brief related follow-up question. Once again, if you have any questions or comments, please press *1 on your phone.
Your first question is coming from Conor Cunningham from Melius Research. Your line is live.
Conor Cunningham
Hi everyone, thank you. Joe, I was hoping to start with you.
Can we just talk a little bit about the progression in unit revenue throughout the second quarter? I'm just trying to get a sense from the difference between the revenue production that you saw in April versus June, just given the mix dynamic as you were more exposed to the higher fares.
Again, not asking for monthly, just trying to understand the spread a little bit as we get a little bit more comfortable with this second-half outlook on revenue. Thank you.
Joe Esposito
Good morning, Conor. It's one of the things that gives us confidence as we go into the back half, and especially the third quarter.
Our exit rate on TRASM was significantly higher than our entry rate. That goes to how our fuel recapture strategy moved through the quarter.
Don't forget we started it in March. In April, we were already 70% booked.
Each month, you get more and more of new-priced revenue that comes through the system. Again, it was significantly higher as the exit rate for both premium and main cabin.
That's what gives us towards our guide for third quarter and our confidence in the back half of the year.
Conor Cunningham
Thank you. Then Ed, maybe bigger picture, a lot of comments around, if we boil it down, it seems like you guys view the industry being a little bit different on how they price going forward, just given the changes that we've seen out there.
You didn't explicitly guide to fourth quarter, but rough math suggests that you expect pricing to remain firm from here. I'm just trying to understand what gives you confidence in that.
I know you've talked a little bit about it, but I was hoping to broaden out the conversation a little bit more. Thank you.
Ed Bastian
Conor, I think it gives us a lot of confidence in the back that we're going to hold on to the pricing environment and the revenue momentum. The industry has no other choice.
The inflation that's going through both on fuel and non-fuel is significant. Fuel prices are still elevated.
That's where we have confidence in holding on to the revenue under a modest capacity increase as well. That would imply a good confidence in the back half.
Our forward cash sales, when you look at both cash and bookings, are higher than our close-in. That's what we want to see when we think about confidence for the back half for the greater than 90, greater than 120 days.
Then as you get into fall for Delta's network, we're much more of a business-oriented network, post-summer environment, not only for domestic, but for international. That's where our confidence comes from in the back half.
Conor Cunningham
Great, thanks.
Operator
Thank you. Your next question is coming from Mike Linenberg from Deutsche Bank.
Your line is live.
Mike Linenberg
Oh yeah, hey, good morning everyone. Hey Ed, this one's for you.
I think, by all measures of market share, it does look like the low-cost, low-fare carrier group, I guess is what I would call it, is in a bit of a secular decline. Look, you've been around for some time.
Sort of thoughts about that. The reason I'm also bringing it up is that, as we think about the industry's ability to hold onto fare increases, I think one of the concerns among investors is that it's going to be carriers from that group that come in and undermine the structure as energy prices come off.
Just your thoughts around that?
Ed Bastian
Sure, Mike. Thanks for that.
What we've seen, and it's not just this quarter, it's been building for the last several years, is that we've seen some fairly significant structural changes to the overall industry landscape. Probably the last time that we saw the element of fuel moving around with a lot of volatility was maybe 9, 10 years ago.
Back then, the low-cost carriers were the darlings of the industry. They had the highest margins, they had the highest growth rates.
They looked fuel as a competitive advantage because they had lower costs in other areas. Some of them, such as Southwest, had fuel hedges in place, which they used to try to take market share.
None of that exists any longer. All of that world has changed completely entirely.
No one has fuel hedges of any note. The cost of production not just for fuel is up, but the cost for labor is up, the cost for airports are up, the cost for technology is up.
Planes, you can't get, and if you can get them, their costs are higher. What that tells you is that you need to figure out a change to the business model that will enable you to build resilience in your pricing durability.
That's what we've done over time. That includes not just getting higher airfares, that includes the diversification of the revenue stream.
That's why our American Express relationship is so important to us. That's why our corporate as the leader for the last 15 years in business travel across the United States is important to us.
That's why our international growth has been important to us. That's why the MRO and cargo are important to us, all of which are growing double digits.
We've been building this, and you wrap that around an experience that is substantially better in terms of the premium experience that we offer today versus 10 years ago, and the opportunity now that we have with technology to become true world-class merchandisers and retailers. 10 years ago, we were a blunt instrument.
We had stick a couple handful of price categories on the shelf. Today, we're continuing to add to that.
What we're seeing here is no surprise to Delta. The fact that you've got others in the industry following our lead is no surprise as well.
I mentioned a point on the call this morning that even with the improvements we've seen in pricing for the industry, the low end of the market still has to increase fares by another 5% by our estimate, just to get to break even at today's fuel environment. There's nothing to be gained by trying to grow in that environment.
The opportunity has to be in finding ways to secure higher revenues, not higher market share.
Mike Linenberg
Very helpful, thanks. Just quick one to Dan.
Dan, you talked about [unclear] actions that you were taking to improve the ops, and you talked about how the numbers had improved through the quarter. I know I saw that there was some talk about maybe on the staffing side.
Anything there or on the fleet side? Any particular fleet giving you problems this quarter?
Dan Janki
Mike, thanks for that. I would say on the fleet elements, you just have to be systematic across the board about continuing to invest in, put resiliency in it.
Our teams continue to get better. We have opportunity to get better on that front.
A lot of that is just capturing your data, more predictive maintenance, staying out in front of it, and continuing to work it. We've seen that, and I talked a little bit about those stats that we're seeing improvement in, but we want to continue to make progress there.
Then the other one that we've talked about is the actions that we're taking around the resiliency and capability around our crew resourcing,
Mike Linenberg
and
Dan Janki
continuing to put more people, process, technology around that, and get better utilization out of those resources. We continue to make progress on that front.
Mike Linenberg
Great, thank you.
Ed Bastian
Thank you.
Operator
Your next question is coming from David Vernon from Bernstein. Your line is live.
David Vernon
Hey, good afternoon or good morning again, thanks for admitting me in here. I guess the one question I had for you, with regards to the CASM-Ex outlook, obviously you made some comments in the prepared statements around CASM moderating, as you get more normalized growth.
Can you talk about what that means kind of for 4Q, maybe beginning of next year, ASM growth, where in the network you're looking to maybe add capacity? Maybe just stepping back from that, where do you see in the marketplace an opportunity to put capacity to work that is compensatory, just given the state of affairs and where oil is?
Thanks.
Ed Bastian
David. It's premature to be out giving guideposts for '27, and I know that's not what you're asking.
We've come through a period here over this quarter, certainly the third quarter, looking forward with muted capacity. It was an obvious response to the fairly dramatic fuel spike that we saw.
Fuel continues to stay elevated. Fuel today is 50% higher than where we started the year at.
I think you're going to find the crack spreads are going to continue to be sticky. I think they will come down, but I think it's going to be sticky coming down, given the questions that sit out there in the Middle East and other parts of the world about kind of damage was done to the refineries and the amount of production capability that you can find.
I would anticipate that in the fourth quarter for Delta, you'll see us kind of return to a little bit more of a normalized capacity run rate, that 2% to 3% that we've historically looked at. It kind of keeps us around in par with where economic growth is.
Then as we go forward to '27, it's probably the mindset that we've had. You guys follow us well, and you've seen how this team thinks about this stuff.
We try to stay in our lane in terms of our strategy. We're not out there trying to compete on someone else's strategy, we're focused on Delta's strategy.
The growth that we're seeing here for the back end of the year going into the next couple of years will largely be in two areas. It'll obviously be focused on profitable growth, but it'll be upgauging.
We've taken a holiday over the last couple of years from upgauging as we've had some fleet resets here. We'll get back in the next year or two as we take delivery of the MAX 10 and some additional narrowbody opportunities to get an upgauge going, and it's a very efficient way to grow.
Secondly, international. The international areas we are growing are in line with our strategies, going into some new markets in the Middle East such as Riyadh, bringing Tel Aviv back, as well as expanding in Asia.
That's kind of the outlook for growth as I see it for the next year or so.
David Vernon
All right, that's helpful. Then maybe just a quick follow-up.
You mentioned that the MAX 10 being out there, MAX 7. It sounds like we're getting a little bit closer to the end of the tunnel.
Do you think that the delivery of some of those aircraft that have been constrained can upset kind of what is a better structural environment, or does that not factor into your consideration?
Ed Bastian
Oh, it absolutely does add to the structural changes. The fuel that powered the low-cost evolution was being able to grow faster than your costs were, with all the aircraft availability from both Airbus and Boeing on the narrowbody side.
That has dramatically changed. By the way, it's not the question of whether Boeing and Airbus can even produce the aircraft as much as the engine producers and the lack of durability that we've seen in the quality of the new engine technologies isn't anywhere close to the pre-existing technologies that we had previously.
I think availability of aircraft is a fairly significant constraint as well. For us, we're looking forward to getting the MAX 10.
We expect to see that in Delta colors next year, which will be great to have, but it's also going to enable us to release some older narrowbodies and whether 717s and 757s that it will be replacement. All right.
David Vernon
Thanks, Ed.
Ed Bastian
Thanks, David.
Operator
Thank you. Your next question is coming from Andrew Didora from Bank of America.
Your line is live.
Andrew Didora
Hi, good morning everyone. Joe, just question on international.
Just curious if we were sitting here in March, how much of your 2Q international was on the books versus 3Q? Because I just ask because international and particularly Atlantic maybe a little bit below what we had thought.
I feel like it could be something with the booking curve, should we be expecting a better sequential improvement internationally because of that dynamic? Any thoughts you can provide on the international geographies would be helpful.
Joe Esposito
Good morning. That's exactly right.
Typically, your long-haul international has about 15 points of bookings more than domestic does. When you were in March, April was very much booked, and customers booked their travel, especially transatlantic for the summer.
They actually start in January and February with that booking curve, where domestic's closer in. You will see sequential improvements as we go through the next quarter and into the fall in terms of that.
That's a good thing. Then also business improves significantly in the transatlantic as you get into September and October in the off-season.
Around the world, transatlantic first, we'll still have a very solid summer. Demand has been very strong, In the past, our foreign point of sale has been a little bit softer, but we've transitioned to more of a U.S.
point of sale, where we're over 80% now for U.S. point of sale in the transatlantic.
That falls back to our strengths. The fares are higher, and the strength of our brand in the U.S.
is much higher. The transatlantic will have a great summer.
The good thing about the transatlantic is it's smoothing out. The seasonality has been flattening, which is good for us, and people are moving their trips more into the shoulders and in the traditional off-season.
Pacific has kept up with capacity. We're actually growing the Pacific, unit revenues were up about 8% on similar capacity.
You've seen us with two new markets this year, Hong Kong and we're annualizing Melbourne, and Los Angeles-Shanghai and Salt Lake City-Incheon. Asia and the Middle East will be the focus for the next couple of years.
Latin is a little bit of two different stories. South America's been very strong this year and for the past really 18 months, and the forwards look really good based on our partnership with LATAM, aligning ourselves with their connecting bank structures in South America.
Mexico had been a little bit weaker as the violence earlier this year. Mexico had been a little bit softer, as well as short-haul.
We'll expect to see improvements in that as we get into the fourth quarter of this year, and our capacity also reflects that. We were down 7% in Latin America, with most of that is in the short-haul category.
We'll bring that capacity back based on demand. It's not assured it comes back.
It's slowly coming back, but we should see a strong winter for leisure travel. Again, South America has really been the bright spot.
Just getting back to domestic again, that had been the lead in unit revenue performance and really strong performance as you exited the quarter on unit revenue versus when you enter. It's good for the participation of all the carriers have come in on fuel recovery the fastest in domestic system, and the fastest we've ever seen historically.
Domestic is on a really good trajectory, especially with corporate sales travelling in the U.S., and a couple of bright spots that while we said 20% for corporate, big cities like Los Angeles and Boston were actually closer to 30%. Really good progression in the domestic system.
Andrew Didora
That's great, very very helpful. Then as a follow-up, actually just wanted to ask about the cabin segmentation you announced earlier this week.
I know you've teased a bit about wanting to give your customers a little further choice. I'm just curious on how far you think this can go.
Are there a further opportunities to continue to maybe expand this a la carte option, and any comments on how you view those options over the next 3 to 5 years could be helpful. Thank you.
Joe Esposito
Thanks. We're really still in the early stages of segmentation.
We've gone through main cabin several years ago, we just recently expanded into Comfort+, and right now we're launching into our premium products. I think it's a great benefit for the consumer, it's a great benefit for revenue upgrades.
It gives the choice to the customer. I think what you can see, and I think we're in the early stages, because I think what you can see for the future is how do we retail all of our products in those categories, and actually reward our best customers, put better and better products into those categories for the future.
Today, it looks very much like a typical revenue management type merchandising, but I think with all the great brands that were associated with, you can see a world where you're merging the retailing with it.
Andrew Didora
Thanks so much.
Operator
Thank you. Your next question is coming from Tom Fitzgerald from TD Cowen.
Your line is live.
Tom Fitzgerald
Hi everyone, thanks very much for the time. Just curious on cargo.
I was wondering if you could unpack some of the strength in 2Q. I don't know if that was just obviously spot prices have surged and there's fuel charges, but I know with some of your fleet investments, there's a cargo angle of that as well.
Then, I don't know, if we should expect that cargo number to decelerate into the back half, or it's kind of continue to show some pretty good strength.
Joe Esposito
Thanks, Tom. Most of what we saw for cargo revenue, it was a great quarter, we're really proud of the team, was on volume.
You've had some rerouting of cargo that typically goes through the Middle East and other areas that we've been able to recapture. It's also the structural improvements we've made internally, which, depending on where we're expanding, Asia is one of the largest cargo markets from the U.S., and we've been expanding in the Asia market.
We've been getting greater capability of our airplanes that we've been investing in. We've done a lot of internal restructuring and how we approach cargos and made it much more of a priority.
We'll see strength throughout the year in cargo. Probably not the 39%, but we're going to have a really strong back half in our cargo sector, and that'll play a bigger role as we continue to invest in international.
Cargo is a big part of international, and goes towards the profitability of our international entities.
Tom Fitzgerald
Great. Thank you, that's really helpful to hear, really encouraging.
Then, I guess just maybe on the MRO side, would you mind just running us through your latest thinking on the kind of margin trajectory of that business moving in the back half and the next couple of years? I know you're longer term have a target of mid-teens, but seem some nice growth year-over-year in the first half.
Thanks again for the time.
Dan Janki
Sure, Tom. What we've talked about is that mid-teens is the target.
We expect to expand a couple hundred basis points a year. The first half of this year was better than that.
We got a lot of volume leverage given the revenue growth that we expected. I would, as you think about this business going from 10% to 12% to the mid-teens with double-digit revenue growth, that would be the progression that I'd look at.
We've been out there, we believe and the team believes that they got the backlog, that they got technical capability, the market position not only to grow the top line, but to grow the margins to double digit, and I would expect about a couple hundred basis points a year.
Julie Stewart
Thank you. Matthew, we can now go to our next question.
Operator
Certainly. Your next question is coming from Jamie Baker from JPMorgan.
Your line is live.
Jamie Baker
Oh hey, good morning, probably for Ed. I'm curious what internal analysis you've done to assess what peak pre-tax margins might look like for Delta in coming years.
Obviously that analysis would have to make a number of industry assumptions as well. Hypothetically, if the industry was doing a 30% pre-tax margin, you'd see a new round of startups and that sort of thing, and I'm not expecting that outcome.
My point is there's bound to be some structural peak as to what Delta margins can accomplish. I'm curious what sort of thought and analysis you've put into this and what you're willing to share.
Ed Bastian
Thanks Jamie. I'm not sure what peak looks like, we're not there yet.
Our framework that we brought to the investors a couple of years ago outlined a pathway to mid-teens margins, and sustainably mid-teen margins. Arguably, a peak environment might be a little bit higher than that.
When you think about what had to happen when we laid that scenario out, a lot of what we made assumptions around is what you're seeing happen. The structural change in the industry is the most important part of it, with respect to the discipline that the industry needs to take in light of high costs, whether it's fuel, whether it's labor, whether it's aircraft availability as well as the cost of aircraft, whether it's the airports themselves, incredibly high-cost business.
Second, you think about the value proposition that we're creating for consumers. We're no longer competing on price as much as we're competing on value, and experience, and service.
That's where Delta wins, that's where Delta has always won. We're going to continue to lean in there.
You look at the efficiency opportunities that we know we have sitting in front of us. Upgauging was a key unlock that last decade to getting out of the small regional jets, and introducing the 321neos and the upgauged narrowbody strategy.
We've got a long ways to go there still on upgauging opportunities and fleet efficiency, which candidly is the only way you can grow in the domestic network given how much congestion there is. It'll be tempered, it'll be modest, but I think it'll be very profitable.
Then you also, kind of think about where the world is. While there will be ups and downs, and bumps along the way, the sustainability of what we're building, because we're building it through a greater experience, and consumers having an affiliation for the Delta brand, is going to be far more durable than anything this industry ever saw.
I tell groups all the time, I started here almost 30 years ago,
Jamie Baker
you
Ed Bastian
asked, you were there. Ask someone why they picked a specific airline, 8 8 at least 80% of the time, it's whoever had the lowest price.
Today, if you ask a consumer why did they choose Delta, they'll tell you it's because it's Delta. Those are the changes.
I think those are durable advantages. Yes, there will be more unexpected surprises ahead, which is also why our balance sheet strategy is so important here, to continue to pay down debt, and enable us for the first time maybe in our history to play offense once in a while when deficits and challenges occur, rather than always having to play defense, and get our debt levels down to much lower levels than they are today.
That's the view, and there's other things as well, but those are the reasons why I think, kind of that mid-teens and the last one I was trying to think, I knew there was one more, is technology. With AI and, I don't know that technology is going to enable us to grow our business, I think that's probably true across most businesses they tell you today, but it's certainly going to enable us to be more efficient, and smarter about how we do business.
We already see some early signs, and while it may take us another year or two before you really start to see a meaningful imprint from that, that's coming. That's not going to be small, I think that's going to be pretty large.
Those are the reasons why I think getting to that mid-teens level is durable and sustainable, and it's led also in the marketplace. You look at our domestic main cabin performance, I saw a stat recently that if we kind of get our margins anywhere close to where they were back in 2019, that's easily 2 to 3 points on the overall margin for our business.
It just gives you a sense the leverage we have here, too, the opportunity.
Jamie Baker
Very very helpful color, Ed. Then just a quick follow-up question on segmenting DPS and D1.
Obviously, one thing that made basic economy such a success was that the majority of corporations forbade consumption by business travelers. I think it was Glen once said something like 90% of your managed corporates had walled off basic economy.
I know it's early in terms of unbundling the premium cabins, and I haven't actually had time to check how JPMorgan is going to handle this, but do you expect a similar broad-based corporate response in terms of kind of walling off the basic premium fares? Is the success of that product predicated on corporates doing so?
Hey Jamie.
Ed Bastian
When we rolled it out to Comfort+, we did exactly that of what we did with main cabin, and we're moving that through the other categories as well. We do expect that to be very similar.
All those fares won't be allowed on every single flight that we have either, we'll use that based on where demand is by flight and by market. I would expect this to be a positive for the top-end consumer of first class as you get more and more flexibility.
Because the basic still even in the premium cabins are restrictive, and that doesn't really work with our corporate customers.
Jamie Baker
Precisely. Yeah.
All right, very helpful. Thank you, gentlemen.
Appreciate it.
Ed Bastian
Thank you, Jamie.
Erik Snell
Thanks.
Operator
Thank you. Your next question is coming from Brandon Oglenski from Barclays.
Your line is live.
Brandon Oglenski
Hi, good morning everyone, and thanks for taking the question. Erik, maybe this one's for you, because I think if we just translate your RASM in the fourth quarter and obviously expectations for low-single-digit CASM, we're getting close to that mid-teens operating margin goal that you guys have long term.
Obviously you want to hit that annually. How do you think about unit cost inflation in '27 and beyond, and how are you going to manage through new labor contracts and things of that matter?
Erik Snell
Thanks, Brandon. Appreciate the question.
We'll continue to have progress on unit costs as we go forward. We're expecting modest progress, mainly on some of the actions that Dan has talked about and getting our resilience better.
We saw exit rate in the quarter, some improvement there. Feeling good about modest progress there, and then into the fourth quarter.
As we get back to normalized capacity growth and see those operational improvements, that's when we'll hit our long-term framework of low single digits. It'll depend on the setup next year in terms of where our capacity is.
The other thing I'd say is that we have all the costs in our baseline. We're top of the industry in our pay scales.
We've got our generational airport improvements in our baseline. Our ability to outperform going forward, we think, is going to be strong as we get back to the low-single-digit CASM.
Brandon Oglenski
Erik, just a really quick follow-up there, because I think you guys have talked about resiliency and staffing this year. I guess is that potentially a tailwind as you look into '27?
Erik Snell
I think it is. We've certainly put in quite a number of actions.
Some of those take some time to mature. We're seeing the fruits of that labor.
It's not just in our crew resilience. We've got efficiency actions across our system.
As we continue to gain growth, you'll see that leverage, right? During the second quarter, with growth below our plan, we were about flat in terms of our resources versus growth.
You start to gain real leverage, and I expect 2 to 3 points of our ability to leverage the resources we have and the investments we've made under the growth that will be coming our way.
Brandon Oglenski
Thank you, Erik.
Operator
Thank you. Your next question is coming from Ravi Shanker from Morgan Stanley.
Your line is live.
Ravi Shanker
Great. Thanks, morning everyone.
Dan or Joe, can you give us some color on load factor by cabin and how you're thinking of balancing load factor versus preserving RASM kind of as we kind of go into the back of the year?
Joe Esposito
Ravi, load factor just in terms of where it's come out or I'm sorry, what are you asking?
Ravi Shanker
Both for how it trended through 2Q, as well as kind of how you're seeing that trends into the third quarter kind of maybe given some of the seasonal changes in 3Q vs 2Q.
Joe Esposito
We're going through peak summer, these are the highest for the year. If you break it down by premium versus main cabin, our premium paid load factor has been very strong and growing.
If you think through this time period, some of the big bright spots has been our paid premium load factor, while main cabin is fairly consistent with what it was last year. Our capacity that we're putting out, we're seeing load factor improvements through that.
We kind of break it up by both cabins. Of course, we're going into peak summer, as we said, transatlantic is peak summer.
As we get into September and October, load factors generally moderate as your business traffic replaces leisure. Then you've got higher load factors as you go through the holiday season.
We expect our load factors where we're putting seats and creating seats, don't forget our capacity in premium is up low single digits, our capacity in main cabin is actually down 2% to 3%. That mix is changing.
The great thing about the mix changing is we're actually able to sell a higher load factor in our premium cabins.
Ravi Shanker
Got it, that is very helpful. Maybe as a quick follow-up, forgive me if I missed this, but what is the current status of the refinery after the outage, and if it's not fully back up yet, what's the timing for that?
Erik Snell
Hey, Ravi. The refinery had an outage about a couple weeks ago.
That was a 5-cent hit to us in the second quarter. We're back up to now approximately 75% throughput of the product that goes through the refinery, but there still will be a tail of the outage into the third quarter.
That's going to be a 5 to 7-cent hit on the third quarter. Net of that, we still expect the refinery to have a 5-cent benefit in the third quarter.
Then, based on where the forwards are now, that benefit would increase into the fourth quarter. Net net, it's
Ravi Shanker
Very helpful, thank you.

Right. Yep, thanks.
Operator
Thank you. Your next question is coming from Duane Pfennigwerth from Evercore ISI.
Your line is live.
Duane Pfennigwerth
Hey, thanks. Good morning and nice results, resumption of the guide, etc.
Just a question on if you think events like the World Cup are benefiting the domestic entity disproportionately? Do you think it kept more demand in the U.S.
this summer, including maybe some premium demand? Then longer term, understanding it's very very early, as you think about next summer, what entities are best positioned in your view?
Joe Esposito
No, there's lots of events that occur throughout the year. World Cup is obviously pretty big.
We're the beneficiary of World Cup. It's not significant enough to make a huge difference to the quarter.
We see it flight by flight, depends obviously where the games are. Now that you've got unscheduled games, you'll see closer-in demand as people are trying to get to that specific city for the game.
I'm sorry, your second part was where the bright spots are for next year?
Duane Pfennigwerth
Just if you think it tilted demand more to the U.S. and how you think that might play out next summer.
Joe Esposito
No, I don't think it's going to make a significant difference of how we deploy capacity next year. We really didn't deploy a lot of capacity this year for World Cup.
We do some additions, but it's actually very small on the grand scheme of the size that we are.
Ed Bastian
I would add an addendum to Joe's comment there. At a much higher level, though, I think the U.S.
has done a wonderful job of showing what a great country we are and welcoming visitation and getting the international inbound back again, both visually as everyone has watched the world. You couldn't have asked, I think, for a better advertisement to come to the USA.
I do think it'll have an impact on the mix in terms of having greater inbound participation in the next year. While it may not change our specific market choices, I do think it'll enhance the mix.
Duane Pfennigwerth
Thanks for that, Ed. If I could sneak just one more in on the co-brand card acceleration that you noted.
Can you talk about the drivers of that, and is there any sort of geographic push behind that acceleration? Thanks for taking the questions.
Joe Esposito
Yeah. Now I think American Express is a great partner, and we're very aligned on our strategic vision about where we grow.
When we go to market, wherever we're expanding, American Express is a critical part of that ecosystem. The growth in cards and the growth in spend is very complementary to how we're both growing.
Both for experiences, whether we're expanding internationally, or Los Angeles, or Boston, or Austin, we're bringing that part with us. It's not just a transactional, it's really a true commercial partnership.
We're happy to get it. We said another million cards per year that should be in our sites this year, as well as $9 billion of remuneration.
It goes with a very tight partnership of Delta and American Express approach to marketplace.
Ed Bastian
I think one of the wonderful benefits of our relationship with American Express is we're two companies that are first exclusive with each other, and two of the leading consumer brands in the country, who have the exact same strategy, the exact same demographic in terms of who we're looking to reach, incredibly complementary in building on each other's strengths. That's why you see the compounded effect year after year after year.
We're not just the largest contributor to the overall distribution of Amex product and cards as well as revenue spend, we're also their fastest growing. They are our number one partner in the world, and we are theirs.
The value you create when you have like-mindedness in the marketplace, it's really powerful, and you see that continuing. Whether you put out new benefits, as we did, with replatformed some of the cards earlier this year, or other opportunities to leverage lounges back and forth, it's a wonderful wonderful strategy that we love our partnership, and I know the Amex people feel the same way about Delta.

Thank you. Your next question is coming from Catherine O'Brien from Goldman Sachs.
Your line is live.
Catherine O'Brien
Hey, good morning everyone, thanks for the time. I just wanted to dig in a bit on the corporate strength you've been seeing.
I think back in January, as you're seeing a little bit of a pickup in corporate volumes following what felt like a really long period of pretty stable volumes post-pandemic recovery. Can you break down how much of the double-digit corporate sales is fare growth versus volume?
If we were to see volumes pick up, how meaningful could that be to premium cabin pricing, given there's been continued strong demand from high-end leisure travelers for these products since the pandemic? Thanks.
Joe Esposito
Hi, Katie. Most of what we saw in the 20% has been on the fare side.
We've seen some improvement in passengers. A lot of it has been in international.
Depends on the specific city that we're focused on. Some cities are growing faster than others.
Most of it's been through the fare environment. There is lots of upside for the future on additional volumes.
It's been great to see the resiliency of the corporate demand.
Catherine O'Brien
Great. Just maybe a quick follow-up on premium and main cabin trends.
I guess first, could you just, you've given us some color on the seats, but could you just tell us what premium versus main cabin RASM growth was in 2Q? Then given the tougher comps in premium and the reduction in low-cost capacity over this year, are you anticipating main cabin RASM could outperform premium underlying your 3Q guide?
Or, obviously I know Delta's been cutting main cabin seats, so that maybe looks a little bit different than the rest of the industry. Any additional color there would be helpful.
Thanks so much for the time.
Joe Esposito
Actually in the second quarter, our unit revenue in main cabin did exceed premium because we we are down in capacity. The industry has removed significant amount of unprofitable capacity.
If you look at the ultra-LCC category, that capacity's down about 30%. Main cabin has gotten significantly healthier this year.
Last year it was one of our biggest objectives to improve the main cabin. Also, we're not growing main cabin seats.
This is a multi-year several years in a row that we haven't grown this cabin, and we won't be growing it next year either. Our our premium revenue has been up 17% and unit revenues below main cabin, but our growth in that category has been up high single digits, while revenue is outstripping the capacity and premium revenue.
It's so I think we're getting into a really good balance between main cabin and our premium cabins.
Operator
Thank you. Your next question is coming from Jon Gordon from Citigroup.
Your line is live.
Jon Gordon
Hey guys, thanks for taking my question. Ed, you're the longest-tenured CEO in the industry, you've seen a lot over that time.
I know that you don't take guiding to what will be a historic and record 4Q earnings number lightly. If you hit that guidance, I think the bigger idea is we'd be set up for a major 2027 breakout year just based on the simple math.
I know people have come at this in different ways on the call, but just to kind of have everything in one place, can you talk about how the slow and consistent changes in the industry and at Delta compounded to set this situation up? Why should we all have confidence that this inflection we're seeing isn't a head fake and is sustainable beyond the end of the year?
Ed Bastian
Sure, John. Thank you for that.
The results you're seeing here and the forecast into the back half of the year, in '27 and beyond, is entirely consistent with what we have previewed to the street over quite a few years. We talk about getting out of the commodity cycle many years ago, and I think we used to call it decommoditization, and today we're up to premium strategy.
Tomorrow, we'll find a more elegant term for it to the future. It's about building a sustainable business model that generates great returns for all its constituents, great rewards for its customers, who are loyal to the airline, great value to its employees through profit sharing and the rewards of working at Delta, and the working for the world's best airline, great for the community, and certainly great for our investors.
This is a pathway that I see continued growth. I don't think we're anywhere close to where we will eventually stabilize at, and even when we get to stable, there's always going to be a next beyond that.
I think the consistency of the strategy, the alignment, the fact that you've got a leadership team who's been here for not just me, but everyone around this table has been here for a lot of years. We all think alike.
The 100,000 people of Delta understand the strategy, and they're all focused on service. If it's about what you can do when you put people first and you make service your goal, it's not about trying to outsmart somebody on some network strategy or trying to undercut somebody on a lower flight price point, this is about who serves best and who creates the best experience.
That's Delta. It's Delta, objectively, not just that I'm obviously biased.
That's what generates the returns, that's what generates the premium revenues, and that's generates our opportunities to continue going, and I don't see any end in that.
Jon Gordon
That's fantastic. I think we might be at the end here, I don't want to hold up the call, I'll leave it at one.

Operator
Certainly. Your final question is coming from Savanthi Syth from Raymond James.
Your line is live.
Savanthi Syth
Hey, good morning. Just to clarify, with your kind of focus on international over the next few years, just taking a longer-term view, how do you see the kind of capacity growth in the kind of the domestic market versus opportunity in international markets?
Just wanted to put a finer point on that as you think longer term.
Joe Esposito
I think longer term, the domestic market is, moves with the economy. International has In international for us will grow faster than average, just because there's a lot of economies that we still don't serve, and we'll grow faster than the domestic market.
I kind of look at our domestic, when you think about being coming more efficient, on the, a good part of capacity for the future in domestic will be efficiency, as as Ed said about gauge growth and getting back to a positive gauge growth, because we don't we don't have a problem with demand. Larger airplanes make us more efficient and give you that extra extra capacity.
I think there's going to be parts of the U.S. that we're focused on where it grows faster than average, where we can find premium markets like Raleigh-Durham and Austin and Los Angeles, as in place like that, that we can continue to enhance the ecosystem for domestic.
I see a lot of efficiency in domestic based on our utilizing our our current hub structure. International, most of it's going to be Asia and Middle East as we continue to add economies that we don't serve.
A lot of it is looking at our customers have a high demand to go to those destinations we don't fly to, like Hong Kong that we just that we just started, or Melbourne, or other other places in South Pacific and Southeast Asia. We've got a great anchor partner in Asia with Korean with Korean Air that allows us to expand ourselves throughout the, through 70, 80 destinations through Asia, and now we have access from all of our hubs.
I think you'll see international grow faster than average, domestic will be the theme will be much more of efficiency.
Savanthi Syth
That's helpful. Just to follow up on that.
Does that put Europe and kind of Latin America, kind of somewhere in between?
Joe Esposito
I see Europe also as efficiency. When you think about the aircraft we've got coming online with 787s, a 787 that replaces a 767, that's a significant amount of efficiency and margin.
Premium, going from 30% premium seating in a 76 to over 50% in a 787, and it can handle twice the cargo. I think the continent of Europe falls into the bucket of efficiency, but on the widebody side, which actually is a multiplier on gauge in long-haul international because of fuel burn and top-line revenue that you can generate.
I kind of put the continent of Europe in the domestic bucket. South America, we still have some opportunities with LATAM.
They've got fantastic hubs that they're developing, like Lima, Santiago, São Paulo, Bogotá, that we're working, and we're in the early stages with LATAM and Korean on our development of our hubs. Typically, our JV partners is the foundation of our profitability and our strategy in those regions, and we've got great partners to work with.
