thanks everyone for the help!

@bigbone & salica: I'll check winair out and see if their flights match our schedule

@manpot: SFO->STT is our other option (actually the one we took last time) but it ends up costing more, taking longer and with the additional hustle of the ferries. Plus on the last day we will need to spend a night at STT because there are few late flights out of STT heading to SFO.

@rita_irvine: that option is more convenient but significantly more expensive, I'd rather go with the ferry.

On the way there there is no real problem if they take longer, being it the last flight. What I'm worried about is the way back. What will AA do if we miss their flight from SXM because LIAT was late? Would they put me on the next flight for free or would they make me pay a change fee or something?
