American Airlines Forecasts Higher 2026 Loss and Slower 2027 Growth

A sharper earnings reset

Rising fuel prices are reshaping American Airlines’ plans: the carrier expects a larger 2026 loss and says its network will grow more slowly next year. Its latest outlook puts fuel costs ahead of revenue gains as the main pressure on earnings, a reminder that stronger sales don’t automatically translate into stronger profits. For an airline, the cost of moving each flight can rise even while customers are spending more, leaving management to weigh expansion against the expense of operating it.

American now forecasts an adjusted full-year loss of $1 to $1.60 per diluted share. At the end of the second quarter in July, its forecast ranged from a 65-cent gain to a 65-cent loss. That swing changes the picture considerably: the company has moved from allowing for a modest profit to anticipating a loss across the full year. The revised range also leaves uncertainty about how severe the final result will be, since its endpoints differ by 60 cents per share.

Fuel costs weigh on the outlook

The airline reported a strong third quarter and still expects fourth-quarter revenue to rise 19.5% to 22.5% year over year. But it’s projecting an average fourth-quarter fuel price of about $4.70 per gallon, nearly twice what it paid in the same period of 2025. That would add roughly $2.8 billion to fuel expenses compared with the fourth quarter last year. Revenue growth is a meaningful support, but the forecast shows how quickly a large operating cost can absorb the benefit of higher sales.

That gap is central to reading the outlook. Revenue measures what the airline brings in; it doesn’t tell you what remains after fuel, labor, aircraft and other operating costs are paid. The source doesn’t break down the full effect of each expense, so fuel shouldn’t be treated as the only factor behind the expected loss. Still, American has identified it as the main pressure on earnings, and the size of the projected fuel increase makes that explanation hard to miss.

American expects an adjusted fourth-quarter loss of 50 cents to $1.10 per diluted share. The higher fuel bill also factors into its plan to restrain capacity growth. “Given elevated fuel prices, American expects network growth in 2027 to slow from 2026 levels,” the airline said. Capacity is a practical lever for an airline: adding flights and seats can support revenue, but it also means committing resources to operate them. When costs are rising, a slower expansion can limit exposure, though it may also constrain how much the airline can grow.

Revenue gains face a tougher test

CEO Robert Isom said Thursday that American’s commercial strategy is working, pointing to revenue gains in premium and main cabins, as well as across domestic and international operations. Those gains suggest the airline is seeing improvement across several parts of its business, rather than relying on one customer segment or route category. But the statement describes revenue performance, not the eventual profitability of those sales. The distinction matters when the company’s own forecast shows fuel costs rising sharply at the same time.

American faces pressure to improve profitability and narrow its performance gap with United and Delta. That comparison puts the latest forecast in a broader competitive context: growth and revenue gains matter, but investors and customers may also look at whether the airline can turn them into more dependable earnings. The source doesn’t quantify the gap or explain how much of it comes from fuel, so there’s no basis here for assigning a precise cause. The immediate challenge is clearer: American has to manage a heavier fuel bill while making progress on profitability.

What the slower growth could mean

American’s plan to slow network growth in 2027 signals that the cost outlook is influencing decisions beyond the current quarter. The airline hasn’t specified the scale of the slowdown, so the announcement doesn’t establish how many flights, seats or routes might be affected. It does show that management is linking elevated fuel prices to the pace of expansion. For travelers, a slower growth plan could mean fewer additions to the network than the airline would otherwise make, though the statement doesn’t identify any particular service changes.

This is more significant than it looks. Airline growth can bring in more revenue, but it can also increase operating costs before the returns are clear. If you’re working in this space, the key question is whether American’s revenue gains can keep pace with costs across the business, not simply whether sales are rising. (And this is the part most people overlook.) A strong quarter can coexist with a weaker full-year outlook when the costs attached to future operations are climbing.

There’s a limit to what this update tells us. American has provided forecasts for full-year and fourth-quarter earnings, an estimate for fuel prices, and a direction for 2027 network growth; it hasn’t supplied the details needed to judge the eventual scale of its capacity restraint. That leaves the next outlook update important for understanding whether fuel remains the dominant pressure and how the company’s revenue performance develops alongside it. The immediate takeaway is plain. Growth has to earn its cost.
