American Airlines is still reeling from Sunday's winter storm

　　American Airlines, which has canceled the most flights of any airline due to Winter Storm Fern, expects two more days of affected operations. 

　　"The impact of the storm is as significant as we've ever seen at American," CEO Robert Isom said during the carrier's Q4 earnings call Tuesday.

　　As of 1 p.m. Eastern time, American had canceled 881 mainline flights, amounting to 30% of its schedule.

　　American, including its network of regional American Eagle flights, accounted for the majority of the 1,800-plus U.S. flight cancellations for the day, FlightAware data shows. 

　　Isom said that between Jan. 23 and Jan. 26, American canceled more than 9,000 flights. The storm, he said, impacted five of the airline's nine largest hubs, most notably its two largest, Dallas-Fort Worth and Charlotte, both of which were blanketed by ice storms. DFW had periods of snow and freezing rain. The ice has lingered since then due to extreme cold in central Texas.

　　Isom said he spent Monday night at the airport. 

　　"Conditions are still a skating rink," he said. He noted that conditions at the airport will begin improving Tuesday. The high temperature is forecast to reach 39 degrees after not exceeding freezing on Jan. 25 and Jan. 26. 

　　In a Jan. 25 letter, American chief customer officer Heather Garboden said Fern's impact has been amplified because impacted cities like Dallas don't have the infrastructure in place to deal with snow and ice. That, she said, "has led to staffing issues as team members plus vendor and federal partners struggle to make their way on the roads." 

　　American has waivers in effect across much of its network for travel scheduled through Jan. 29. 

　　CFO Devon May estimated that the storm will have a revenue impact of between $150 and $200 million and will reduce American's flown capacity for the first quarter by 1.5 percentage points. 

American falls short of revenue forecast

　　For the fourth quarter, American reported operating revenue of $14 billion, up 2.5% year over year but below analyst forecasts by $30 million, according to finance website Seeking Alpha.

　　The carrier reported operating income of $451 million, down 60.2% from 2024, in part due to a revenue hit of $325 million from the federal government shutdown in October and early November. American's operating margin for the quarter was 3.2%. Net income was $99 million. 

　　For full-year 2025, American reported operating revenue of $54.63 billion and an operating margin of 2.7%. The airline's operating income for the year of $1.47 billion was down 43.9% from 2024 amid a generally weak industrywide environment for main cabin domestic flying.

　　American's net income for 2025 was $111 million, down from $846 million in 2024. 

　　In the first quarter of 2026, the airline expects 7% to 10% higher revenue on 3% to 5% more capacity. American is forecasting full-year earnings per share of $1.70 to $2.70.
