We're also from Pennsylvania, and much prefer Delta over AA from our past experiences. Have flown Delta to SXM from Buffalo to Atlanta to SXM twice in the past, and both times it has been flawless. Delta has a better 'on-time' track record IMO, and only once have they cancelled a flight on us. With AA we've had too many issues in the past to mention. Did you check out Jet Blue? Just returned and everything was perfect, except for no video entertainment on return flight from SXM to Ft. Lauderdale. They apologized, and told us vouchers would be sent this week to all of us! Wow. I just read my book instead. We did Buffalo to JFK to SXM going, and SXM to FLL to BUF returning and we're quite pleased.
