I have flown to SXM from Boston/Providence 3 times. . . each time there was a problem. When you're heading back from a great vacation, even a terminal change without notice is frustrating. Checking fares religiously, i've also found that AA/USAir is markedly higher. Delta seems to be there worst. Now having flown JetBlue, it's the only airline i'd chose. . .i find them to be lower and if you see a lower price within 2 weeks of purchase they'll credit your JB account.
