We are from the midwest and JetBlue is not a carrier here. We are heading to Cancun for a buisness conference at the end of January. We can take Southwest airlines to Orlando and stay a few days at WDW (my idea) and take JetBlue to Cancun and then take it back to Orlando, and stay another night or two at WDW.Is JetBlue reliable? They have a direct flight from MCO to Cancun and back. Do they cancel flights easliy or make many changes? SW is so reliable. I would appreciate ant comments on the airline. Thanks!
