Despite a broadly positive backdrop on Wall Street, American Airlines shares underperformed peers this week. Volume at the carrier’s shares was 25% above the 30-day average, highlighting significant investor activity. Analysts point to concerns over rising labor and fuel costs, which have eaten into recent profit margins, as well as lingering uncertainty around consumer demand for leisure travel in the first half of the year.

The carrier has already canceled over 1,800 U.S. flights in anticipation of a major winter storm forecast to cover two-thirds of the country. Dallas–Fort Worth International Airport, one of American’s key hubs, has seen more than 350 cancellations to date. Management warned that de-icing delays and crew reassignments could raise operational costs by up to $50 million this quarter and reverberate through the network for weeks.

In response to comments by United Airlines’ CEO about American losing over $1 billion at Chicago O’Hare this year, American’s leadership defended its local strategy. The company highlighted three recently launched routes from ORD that have achieved an average load factor of 82% in December, and pointed to a 12% year-over-year increase in premium cabin bookings out of the hub. Executives argue these figures contradict competitor assertions and expect O’Hare to break even by mid-2026.

Analysts projecting fourth-quarter results are also focusing on unit revenue trends and cost per available seat mile (CASM) excluding fuel. Consensus forecasts call for a 4% year-over-year uptick in overall passenger unit revenues and a 2% decline in CASM ex-fuel, driven by expanded international service and continued hedging benefits. Investors will scrutinize these metrics closely at the February earnings release to gauge whether American can sustain margin gains heading into the spring travel season.
