I'm trying to coordinate a Christmas trip and am about ready to throw in the towel. Probably would have already, if I hadn't stupidly put down a deposit to reserve the accommodation. And that'll be nearly impossible to book anywhere else this close in.

With interlining checked baggage, is the decision to do this on the "first" carrier and the second carrier will "accept", or dependent on an interline agreement between the two carriers? I'd have to take a small carrier AA is not partners with, (so separate tickets), to then transfer to an AA flight back to the states through BGI.

I'm wondering specifically about checked bags in this scenario - if anyone knows if AA interlines with any of these outfits and the baggage would be checked through? 1) interCaribbean Airways, 2) Caribbean Airlines, 3) SVG Air/Grenadine Alliance
