Suffice it to say that 2025 has been a turbulent year so far for airlines, particularly in the United States, given the economic turbulence that we’ve seen.
Delta Air Lines has consistently been the most profitable airline for years, and typically kicks off the airline earnings season. The Atlanta-based carrier has just announced its Q2 2025 financial results, and they’re better than expected.
Delta stock surges as airline reports solid results
Delta stock is surging by roughly 13% pre-market, following the carrier announcing its financial results. Not only was the performance better than expected, but the company has also reinstated its full-year outlook.
At the beginning of the year, Delta claimed that 2025 would be its most profitable year in history. While that’s no longer expected to be the case, the airline still expects to make a healthy profit. For Q2 2025, the airline reported:
- Operating revenue of $15.5 billion, up 1% compared to $15.4 billion in Q2 2024
- An operating margin of 13.2%, down 10% compared to 14.7% in Q2 2024
- Pre-tax income of $1.8 billion, down 10% compared to $2.0 billion in Q2 2024
- Earnings per share of $2.10, down 11% compared to $2.36 in Q2 2024
- Total revenue per air seat mile of 19.97 cents, down 3% compared to $20.64 in Q2 2024
- Operating expenses of $13.5 billion, up 2% compared to $13.1 billion in Q2 2024

Looking at more specific trends, international revenue grew 2%, premium revenue grew 5%, cargo revenue grew 7%, loyalty revenue grew 8%, and American Express renumeration grew 10%. Furthermore, fuel costs were down 11%, which certainly helped margins as well.
The airline now expects Q3 2025 revenue to be flat to up 4% compared to the same period last year, with adjusted earnings per share of $1.25-1.75. Delta has also reintroduced its full year earnings projections, expecting adjusted earnings per share of $5.25-6.25. However, the airline notes that it will provide an update on its outlook once “current uncertainty” is over.
Here’s how Delta CEO Ed Bastian describes these results:
“In the June quarter, Delta delivered record revenue on a 13% operating margin, generating $1.8 billion in pre-tax profit and leading network peers across key operational metrics. This strong performance is a direct reflection of the outstanding contributions of our people, who continue to set the bar for industry performance.”
“As we look to the second half of our centennial year, we remain focused on executing our strategic priorities and managing the levers within our control to deliver strong earnings and cash flow. Reflecting our confidence in the business, we are restoring financial guidance with an expectation for earnings per share of $5.25 to $6.25 and free cash flow of $3 to $4 billion, consistent with our long-term free cash flow targets.”

Have airlines actually become resilient businesses?
Historically, whenever there was any sort of an economic downturn or uncertainty, airlines would be in huge trouble. They’d be mildly profitable during the best of times, and would nearly instantly lose money when there were even signs of any economic problems.
So it’s pretty impressive to see how resilient Delta has become. In fairness, part of the issue is the profitability divide we’re seeing in the industry — Delta, United, and Alaska have solid margins, American and Southwest are profitable, but don’t have great margins, and everyone else in the US is seemingly in trouble.
Several months back, it was looking like airlines were going to be in for a rough ride, but at least in the case of Delta, things are still looking to be quite good. Sure, the airline might not reach its goal of having the most profitable year ever, but it’s still expecting to deliver healthy profits.
I think the situation at airlines is pretty reflective of what’s happening in society at large — premium demand is strong, while non-premium demand is really struggling.
Is premium demand just going to be permanently strong? If so, is that because the stock market is strong due to the current tech/AI revolution, or is it because many Gen Z folks are struggling with affordability, and with the goal of buying a house seeming unrealistic, they’re instead treating themselves to better day-to-day experiences (I realize that’s an oversimplification, but I do think it reflects the general “vibe”)?
Post-pandemic, a summer trip to Europe has basically become standard for so many Americans, and airlines are certainly capitalizing on that. I’m curious to see how demand evolves in the fall, especially with so many summer trips increasingly being earlier in the summer rather than later. Nowadays, the peak summer demand really only goes through early August, and not early September, as used to be the case.

Bottom line
Delta has reported its Q2 2025 financial results. While it won’t be Delta’s most profitable year in history (as the company had hoped), the airline beat expectations, especially given the uncertainty we’ve seen in recent times. The airline reported record revenue, but margins are down a bit compared to last year, which isn’t surprising.
As you’d expect, continued profitability has largely been thanks to premium demand and the loyalty program, reflecting the overall industry trend. With the exception of United, don’t expect other airlines to weather this situation quite as well.
