I'm not sure what the deal is with SJU, why so many carriers have left there. AA used to fly an airbus from there to St. Maarten years ago, a couple of times a day, I think. Jet Blue WAS flying from there to SXM for a couple of years, and they stopped those flights a few months ago and there is no big plane service at all from SJU to SXM any more. They've got kind of a nice airport there at SJU now, and I'm guessing that HUGE Margaritaville there is open by now, but can't imagine it's very busy..
