Yes, we used them in late March to get from SJU to EIS and from EIS back to SJU. The flights were uneventful and on time!

On the way to Tortola, the stewardess asked where we were going to stay. We told her Jost. She moved me to the side of the plane where I could get fun shots of Jost and our villa as we flew over.

The only weird part is finding them when you get into SJU from the states. It is in the original part of the airport down past the Margaretville type restaurant. The counter didn't even indicated Intercaribbean. The staff at the counter were from another airline, but they indicated we were at the right place, and to have a seat. Sure enough, 45 minutes or so before our flight the IC staff arrived and moved us through the process.
