Delta Air Lines on Wednesday forecast second-quarter profit below expectations and said it would pull all planned capacity growth from the June quarter as soaring jet fuel prices driven by the Iran war squeeze margins.
The move will reduce supply by about 3.5 percentage points from the original plan.
The Atlanta-based carrier also cited a “downward bias” for growth “until the fuel environment improves.”
It added it was too early to update its full‑year outlook, citing uncertainty over fuel prices.
The US carrier’s forecast highlights the growing strain fuel costs are placing on airlines after the Middle East conflict sent shockwaves through energy markets.
Since late February, jet fuel prices have nearly doubled, marking the industry’s first major post-pandemic stress test by inflating costs, disrupting schedules and pushing the limits of what travelers will pay.
However, there were some signs of relief on Tuesday after President Trump said a two-week ceasefire agreement had been reached with Iran.
Delta shares extended their premarket gains following its results and were last up 10% in early trading.
Shares of rival carriers were also up in morning trading, with United Airlines up 14%, American Airlines gaining 11%, and Southwest Airlines adding 13%, buoyed by hopes of lower jet fuel prices and Delta’s earnings beat.
Fuel typically makes up about a quarter of airline operating costs, leaving carriers particularly exposed when prices jump faster than fares, with tickets often sold weeks or months in advance.
Delta expects to pay about $4.30 a gallon for jet fuel in the June quarter, adding more than $2 billion to its fuel costs compared with a year earlier.
Delta, in January, forecast full-year adjusted earnings of $6.50 to $7.50 per share. While it did not withdraw the outlook on Wednesday, CEO Ed Bastian declined to update it, citing uncertainty over the duration of the fuel‑price spike.
Analysts now expect earnings of $5.40 per share, according to data compiled by LSEG.
So far, airlines have relied on strong travel demand to recoup a part of the higher fuel bill through fare increases, baggage fees and other ancillary charges.
Delta also expects a $300 million benefit from its refinery in the second quarter, up from about $60 million in the March quarter as refining margins widened.
The surge has also raised the prospect of an industry shakeout, with weaker airlines more likely to cut capacity, take on debt or absorb deeper losses, while stronger rivals continue investing and gaining market share.

Bastian said Delta aims to recover about 40% to 50% of higher fuel costs in the second quarter as it lifts fares. He, however, said it would take longer to fully recapture the increase.
Bastian warned the fuel price spike would accelerate structural change across the airline industry.
“It’s going to separate the winners and force the weaker players to take some pretty significant steps to either get better or something else will happen,” he said.
“Non-main cabin revenues continue to fire on all cylinders,” TD Cowen’s Tom Fitzgerald said on Wednesday, adding that Delta’s second-quarter results reflected the durability of its business model.
To conserve fuel and protect margins, airlines have begun trimming schedules, particularly on lower-margin routes and less time-sensitive travel. Since March 13, U.S. carriers have reduced planned domestic capacity growth by more than half a percentage point.
Delta expects adjusted earnings of $1 to $1.50 per share in the June quarter. The midpoint of the forecast, $1.25 per share, is below the $1.41 analysts expect on average, according to LSEG.
On Tuesday, Delta announced plans to raise checked-bag fees, following similar moves by United and JetBlue Airways.
Bastian signaled the higher fees could stick. “At this level of fuel, it’s hard to call anything temporary,” he said.
He also played down concerns that higher fares and fees could weigh on demand, saying ticket sales have risen at a double-digit pace year-on-year over the past month, with momentum carrying into the second quarter.
Higher-income travelers remain resilient and Delta has yet to see any impact on demand, he said.
For the March quarter, the airline reported adjusted earnings of 64 cents per share, topping analysts’ expectation of 57 cents.
