The U.S. military operation that officials say resulted in the capture and removal of Venezuelan President Nicolás Maduro early Saturday also triggered widespread disruptions to air travel across the Caribbean during one of the region’s busiest holiday periods.

Flight-tracking data from FlightRadar24 showed that no commercial airline flights were operating over Venezuelan airspace that day. Following the operation, the Federal Aviation Administration imposed flight restrictions that led major airlines to cancel hundreds of flights across the eastern Caribbean and warn passengers that delays could persist for several days.

Flights to and from Puerto Rico, the U.S. Virgin Islands, Aruba, and more than a dozen destinations in the Lesser Antilles north of Venezuela were affected. Several airlines waived change fees for travelers forced to rebook their plans.

U.S. Transportation Secretary Sean Duffy said Saturday night that the restrictions would be lifted at midnight Eastern Time, allowing airlines to resume normal operations on Sunday.

Southwest Airlines said it added six additional round-trip flights to Puerto Rico on Sunday and eight more on Monday to help stranded travelers return home. The airline also scheduled two extra flights to Aruba on Sunday.

At Queen Beatrix International Airport, officials said they expected operations to return to normal on Sunday after a day of cancellations left many travelers stranded or unable to reach the island, which lies about 15 miles (24 kilometers) off Venezuela’s coast.

In Barbados, Prime Minister Mia Mottley said at a news conference that the situation had severely affected both the country’s airport and its seaport, where cruise ships operate.

Travelers across the region were left scrambling. In Puerto Rico, Lou Levine and his family were scheduled to return to the Washington, D.C., area Saturday morning when they learned their flight had been canceled. After unsuccessful attempts to rebook by phone, they turned to social media, where JetBlue ultimately helped secure new flights.

The disruption extended the family’s planned one-week New Year’s vacation into a two-week stay. Levine said he was fortunate to have a flexible employer, but noted that his daughter would miss a week of high school and that the unexpected extension brought additional costs.

Airlines and airport officials said they expect lingering effects as operations fully normalize, even after flight restrictions are lifted.
