American Airlines Group Inc. (AAL) shares dropped Tuesday after the carrier delivered mixed fourth-quarter results, combining record revenue with disappointing earnings and a sobering outlook clouded by what management described as the worst weather event in company history.

The airline posted record quarterly revenue of $14.0 billion, up from $13.7 billion a year earlier, and full-year revenue reached $54.6 billion compared with $54.2 billion in 2024. But here's the thing: revenue growth doesn't mean much if your costs are climbing faster and Mother Nature keeps grounding your planes.

Fourth-quarter total operating revenue came in at $13.999 billion, a 2.5% increase year over year, while full-year operating revenue rose 0.8% to $54.633 billion. The company noted that a government shutdown late in the quarter chopped approximately $325 million off revenue—not exactly the way you want to close out the year.

American Airlines reported adjusted earnings of just 16 cents per diluted share, well below the 34-cent analyst estimate. Revenue of $13.999 billion also missed the $14.028 billion consensus forecast, disappointing investors who'd hoped for stronger momentum heading into 2026.

Operating margin tells the story more bluntly: it fell to 3.2% from 8.3% a year earlier, reflecting higher costs and operational chaos during the quarter.

The Operational Picture

Revenue passenger miles increased 1.5% year over year to 61.596 billion in the fourth quarter, while available seat miles rose 4.2% to 74.472 billion. The problem? Passenger load factor—a key measure of how full planes are—declined to 82.7% from 84.9%. Translation: American added capacity but couldn't fill those extra seats as efficiently.

Passenger revenue per available seat mile fell 2.0% in the quarter, and total revenue per available seat mile declined 1.6%. Meanwhile, average aircraft fuel prices increased to $2.42 per gallon from $2.34 a year earlier, squeezing margins further.

Regional performance was mixed. Domestic passenger revenue increased 1.5% year over year to $9.191 billion. Atlantic passenger revenue jumped 7.5% to $1.423 billion, Pacific passenger revenue rose 8.3% to $395 million, while Latin America passenger revenue dipped 0.9% to $1.648 billion. Total international passenger revenue climbed 3.5% year over year to $3.466 billion.

Balance Sheet And Cash Flow

Full-year net cash from operating activities came in at $3.099 billion, down from $3.983 billion in 2024. Free cash flow for 2025 was negative $83 million—not a number anyone wants to brag about.

The company ended the year with $954 million in cash and $9.2 billion of total available liquidity. Total debt stood at $36.509 billion at year-end, though management emphasized it reduced total debt by $2.1 billion during 2025, which is at least moving in the right direction.

Management's Take

Despite the near-term turbulence, executives maintained an optimistic tone about the long-term trajectory. The CFO said the main cabin is expected to deliver strong year-over-year improvement in 2026, assuming the economy doesn't fall apart, while premium seat growth is set to outpace regular offerings for the rest of the decade. The CEO added that lie-flat seats are projected to increase by more than 50% by 2030 as the airline pushes harder into higher-yield segments.

Management acknowledged short-term headwinds, noting that Winter Storm Fern would likely cause at least two more days of elevated cancellations before operations normalized. Government-related travel took a serious hit in the fourth quarter, with traffic down about 50% due to the government shutdown. Going forward, the company plans to expand its international fleet and premium seating through new aircraft deliveries and retrofit programs. Management also said it has fully restored its historical indirect sales and distribution share, refocusing on growth from 2026 onward.

Looking Ahead

American Airlines guided full-year 2026 adjusted earnings per diluted share of $1.70 to $2.70, compared with the analyst estimate of $1.97, and expects free cash flow of more than $2 billion—a significant improvement from this year's performance.

For the first quarter of 2026, the company projected an adjusted loss per diluted share of 10 cents to 50 cents, compared with the analyst estimate of a 30-cent loss.

The outlook reflects the brutal impact of Winter Storm Fern, which has resulted in more than 9,000 flight cancellations and is expected to reduce revenue by $150 million to $200 million. The company called it the largest weather-related operational disruption in its history, which is saying something for an airline that's been around for decades.
