Not sure I'm the right person to answer this for you, but I have flown from SXM to JFK, Atlanta, Ft. Lauderdale, etc. multiple times over the years and if i had to rank U.S. airlines coming back to the states from St. Martin my order would be (1). Jet Blue (almost always on time flights and often ahead of schedule, roomier seats in coach, good selection of snacks though have have trimmed the list down a bit on our most recent flights; (2). Delta (usually most flights in the past have been on time, and their scheduling has been fairly consistent from my experiences); and (3). United (only stranded me once, and that was in Chicago for nine long hours; otherwise I've done okay with these guys). Hope that helps a little.
