Airlines have canceled flights to and from the Caribbean as airspace is closed over the area due to U.S. military action in Venezuela.

Secretary Sean Duffy said restrictions on air travel would expire at midnight and airlines "will update their schedules quickly."

US airlines began rebuilding their Caribbean operations Sunday after a US military incursion in Venezuela triggered airspace closures across the region, stranding thousands of passengers trying to return home from winter vacations.

The United States has lifted flight restrictions that had been imposed following a U.S. military operation in Venezuela. This ban, which affected commercial air travel, officially expired at 12:00 a.m.

Airlines resume Caribbean service after FAA lifts airspace restrictions following US Venezuela operation, scramble to add capacity for stranded passengers

JetBlue, which serves Fort Lauderdale-Hollywood International Airport, told CNBC that it canceled more than 200 flights to the Caribbean, but that the Dominican Republic and Jamaica are not affected. Major U.S. airlines don’t serve Venezuela directly.

After airspace over the Caribbean was blocked, leaving travelers stranded, American Airlines rushed to add more flights.

No airline flights were crossing over Venezuela that day, according to FlightRadar24.com. And major airlines canceled hundreds of flights across the eastern Caribbean region and warned passengers that disruptions could continue for days after the Federal Aviation Administration imposed restrictions.

Transportation Secretary Sean Duffy announced overnight that the Federal Aviation Administration (FAA) would allow airlines to resume flights in the Caribbean after flights were canceled amid U.S.

Other carriers have also resumed operations. United Airlines has restored its Caribbean schedule and added additional flights to assist displaced travelers, while JetBlue Airways says it has rebooked passengers and added flights where possible after canceling more than 200 flights during the closure.
