Flights cancellations continue Wednesday with American, Southwest bearing the brunt

Flight cancellations are mounting Wednesday as dangerous winter weather extends across the Southeast this week.

A winter storm warning will remain in effect until Thursday morning across swaths of north and central Texas, with mostly freezing rain and sleet expected in the area, the National Weather Service in Fort Worth warned.

More than 2,300 U.S. flights were canceled around 6 p.m. ET Tuesday, with over 3,100 more delayed, according to flight-tracking website FlightAware. Southwest and American Airlines, which are both based in Texas, saw the most cancellations, scrapping around 17% and 28% of their schedules respectively.

More than 5,400 U.S. flights have been canceled since Monday.

While the Department of Transportation requires airlines to issue refunds to travelers whose flights are canceled, airlines also began issuing waivers as the winter weather rolled in. The cold front comes after a winter storm disrupted flights last week.
