We did it when my brother and his family booked last minute and could only get flights to STT. We have neighbors who always do it that way. We used Fly BVI both ways. Going back there were just four of them, so it was their smallest plane. Worked beautifully. The only caveat is to allow enough time for Immigration, Customs, check-in and Security in St. Thomas.

Curious where you’re coming from. We’ll be making our fifth trip since Irma, and been able to get decent prices into EIS. Some trips we’ve used miles; others we’ve done separate flights through San Juan. Have you looked at Southwest/InterCaribbean? Or Seaborne.
