More than 1,300 US flights were canceled Monday as a winter storm engulfed the southeast, adding to Sunday's travel misery.
As of 8:00 a.m. ET on Monday, 1,314 flights to, from, or within the US had been canceled, per data from FlightAware, the flight-tracking website. This included 407 flights to or from Charlotte Douglas International Airport, making up almost a third of the airport's schedule for Monday.
Airlines canceled 3,058 flights to, from, or within the US on Sunday, according to figures from FlightAware. A further 4,671 flights were hit by delays, the data showed.
Sunday's cancellations included more than 1,200 flights that were scheduled to land in or depart from Charlotte, which represented more than 90% of the airport's schedule for Sunday.
Almost 400 flights set to land in or depart from Hartsfield–Jackson Atlanta International Airport were canceled Sunday, per FlightAware data.
Hundreds of flights to and from Ronald Reagan Washington National Airport in Virginia, Chicago O'Hare International Airport, Raleigh-Durham International in North Carolina, and LaGuardia in New York City were also canceled.
American Airlines, which has a hub at Charlotte International, had the highest number of cancellations, with 674 flights being cut on Sunday, according to FlightAware data. This amounted to almost a quarter of its US-wide schedule for the day.
More than 500 flights operated by American subsidiary PSA Airlines, or 71% of its schedule, were canceled.
Delta said it canceled about 500 flights Sunday and 75 on Monday.
Southwest, Republic, and United all canceled at least 10% of their Sunday schedules, per FlightAware data. The airlines did not immediately respond to Insider's requests for comment, which were made outside normal working hours.
The cancellations were in part due to a winter snow storm which the National Weather Service said could lead to hazardous travel, fallen trees, and power outages for portions of the eastern US through Monday. The agency said parts of New England should expect heavy snow Monday and that the Atlantic coastline could face strong winds and coastal flooding.
American Airlines said in a statement Friday that "winter weather" may affect its operations, and issued travel alerts for some airports in parts of the Midwest, Northeast, and Southeast US, as well as Canada. Southwest warned customers that some flights over the weekend could be delayed, diverted, or canceled. Delta issued a travel waiver.
Airlines have canceled thousands of flights since Christmas Eve, citing bad weather alongside rising staff sickness as the Omicron coronavirus variant spreads.
