Has anyone flown from GC on Cayman Air to Miami & then transferred on to a AA flight? I was wondering if once you clear customs & immigration, do you have to collect your luggage & then proceed to AA to check in for the AA flight? Or does Cayman Air transfer your luggage to other airlines for you? Found a low price for returning to Boston during Christmas week for $377 compared to US Air $621 for 6 people. Is it worth considering this option given the savings?
