Ahead of Hurricane Irma’s impact on the south Florida coast, Delta has cancelled flights to and from Miami, Ft. Lauderdale and West Palm Beach beginning Friday night. Delta’s operation at the three primary south Florida airports will remain suspended through Sunday and will restart pending a facility assessment.

Approximately 260 flights have been canceled for south Florida operations between Friday evening and Sunday. Delta will also suspend its Friday and Saturday operation in Key West ahead of the storm.

Before suspending service at Miami, Ft. Lauderdale and West Palm Beach, Delta will operate a near-full schedule from the airports Friday and has also added more than 1,000 seats out of those airports to help customers evacuating the area. Delta will operate extra flights and upsize the aircraft on select routes to Delta’s hubs.

The airline continues to monitor the track of the storm and will update its operational plans pending an updated forecast. Since Wednesday through Sunday, Delta has canceled roughly 320 flights, which includes flights to the Caribbean and Bahamas.
