Neely,
Did the same thing to tortola this summer and it was awesome. Don't know who you work for, but if you have international jumpseating with AMR then you're good. UPS doesn't have international jump seats with AMR so Cape Air is how I got back to SJ. However... I did talk to the gate agent and the computer system would not let her book me on the jumpseat, so she put me on the STT jumpseat and then transferred me over to Tortola. So Eagle took me there, but they couldn't bring me back and I got to get back into a C-402 again. Great experience all in all.... have fun....
