I'm using AirSunshine for the first time next month from SJU to Virgin Gorda.

We've used Seaborne a couple of times with good results, ditto for Cape Air.

We have flights booked in May on Jet Blue into San Juan but haven't booked our flight to the BVI from SJU yet - it will likely be on Seabourne.

Flying back 6/6 out of EIS for the return and booked the whole thing via Delta using Seabourne out of EIS and connecting in SJU on to Tampa.
