After many travelers complained that prices for flights out of Florida ahead of Hurricane Irma were suddenly skyrocketing, several airlines are now capping fares and, in some cases, opening up more seats to meet demand.

Delta Air Lines

Delta is switching to larger aircraft and adding flights to airports in Punta Cana, Nassau, Freeport, Key West, Miami, Ft. Lauderdale, Sarasota, Orlando, and more. The airline also says that more than 2,000 seats have been added to airports along Irma’s path to help customers evacuate the area.
