Just got notified that our 5PM flight out of SJU next month was changed to a different flight number and a 3:03PM flight same day/same seats (EMS seats).

Looked on their schedule and there is a 4:03PM flight, actually cheaper if you were to go online and book it, and the same seats were available, so I did an online chat and switched to the 4:03.

Not sure why they put us on the earlier one automatically. Kind of surprised to see such a dramatic change in flights on such relatively short notice from Jet Blue, as they are usually much more reliable than the Deltas and Americans of the world in terms of flight changes
