US airlines taking government funding during the coronavirus pandemic had been required to maintain service to all their destinations. But airlines have been asking for exemptions from this requirement citing low passenger demand, and the Department of Transportation (DOT) has allowed 15 US airlines to drop their service to 75 airports.
United and Delta airlines were approved to drop flights to 11 airports, Allegiant Air was allowed to stop service to six airports, and JetBlue, Alaska, Spirit, and Frontier airlines were each allowed to drop flights to five airports.
