US Airline Earnings Signal Fares Won't Drop This Summer

Delta Air Lines and United Airlines just gave travelers their clearest signal yet that summer 2026 airfares are not coming down anytime soon. Delta reported its second-quarter results on July 10, and United followed on July 15, and both told the same story: jet fuel costs have spiked so sharply this year that airlines are leaning hard on higher ticket prices to stay profitable, and they intend to keep leaning on them through the rest of the year. The fuel numbers explain why. Delta said it paid an average of $3.93 a gallon for jet fuel in the quarter, up 75% from $2.25 a year earlier, and called it the highest quarterly fuel bill in company history at $4.4 billion. United had it even worse, with fuel expense jumping 84% year over year to $5.11 billion at an average price of $4.19 a gallon. United now expects almost $6 billion in extra fuel costs for all of 2026 compared with what it had budgeted at the start of the year. Both carriers pointed to the ongoing Middle East conflict as a major driver of the spike in crude and refined fuel prices. Rather than absorb that hit, both airlines are passing a large share of it on to passengers. Delta's revenue gain for the quarter came almost entirely from higher fares rather than flying more seats, with capacity up only about 1% while adjusted revenue climbed roughly 14%; the airline said fare increases covered about 60% of the jump in its fuel bill. United reported yields up 12% for the quarter and raised its full-year adjusted earnings guidance to $9-$11 per share, up from a prior range that started as low as $7, largely because pricing power let it recover about half of its extra fuel costs in the second quarter alone. United expects to recover 80-90% of the elevated fuel costs in the third quarter and effectively all of it by the fourth quarter, which is a fairly direct statement that fares aren't going to soften before the December holidays. Both airlines are also keeping a tight lid on how many seats they're adding, which matters as much as fuel costs. When capacity growth stays low industry-wide, there are fewer empty seats competing for buyers, so carriers have more room to hold prices up even if fuel eases later in the year. That combination, tighter capacity plus persistent fuel pressure, is why analysts and the airlines themselves are not forecasting meaningfully lower fares through the rest of 2026. What this means if you're booking: if you have US domestic or international-from-the-US travel planned for August through the December holidays, book sooner rather than later. Waiting for a fare drop based on the hope that fuel prices will ease is a weak bet right now, since both major carriers have explicitly built their guidance around recovering elevated costs through fares over the next two quarters, not around cutting them. If your travel dates are flexible, midweek departures and shoulder-season windows (late August, early-to-mid September, and the first half of December) still tend to price lower than peak weekend and holiday travel, so shifting a few days can offset some of the broader fare increase. Business and premium travelers should also expect less discounting than usual, since Delta and United both reported strong premium-cabin demand growth, which reduces the incentive for airlines to run aggressive fare sales in those cabins. Budget travelers should watch for ancillary fee increases too: when fuel costs rise and fare increases alone don't fully close the gap, airlines have historically turned to bag fees and other add-ons, so factor those into your total trip cost rather than comparing base fares alone. American Airlines reports its own Q2 results on July 23, and Southwest is expected shortly after; if either signals a different pricing strategy, particularly Southwest, which has historically competed more on price, it could be worth a second look at fares in the following days. Until then, the two largest US carriers by revenue have said plainly that they're keeping prices elevated to cover fuel costs, and travelers should plan and book accordingly.
