Silver Airways, the parent company of Seaborne Airlines, launched summer flights from San Juan to Anguilla with twice-weekly roundtrip service on Thursdays and Saturdays through Aug. 6.
Travel time is an hour each way.
Silver Airways has codeshare agreements with American, JetBlue, Delta and Copa.
"The San Juan gateway is vital to the growth of our tourism industry," said Haydn Hughes, Anguilla's minister of tourism.
"Maintaining and expanding access to Anguilla is essential for our tourism development, and the restoration of this service is an important step as we reopen our island to international travelers," he said.
