My niece flew Jet Blue JFK-SJU at the end of February. They were 1 hr 45 min. late due to a delayed crew. Fifteen people on the flight were connecting on Silver to Tortola - all of them missed their flight.

Jet Blue has onboard Wi-Fi, so we knew what was going on. Fortunately my SIL was able to get the kid a seat on Cape Air. I never boat after dark, but I wasn't going to let a girl who just turned 20, and who suffers from anxiety, spend the night alone in the San Juan airport hotel. We brought her home from Trellis Bay after dark. A family of five, with baby, heading for a rental on our island, all got stuck in San Juan, and there were no seats the following morning.

Jet Blue did refund the entire ticket from JFK to Tortola. But the Cape Air ticket cost plenty.
