Well they did it again USA3000 called this morning and cancelled our flight to Cancun Thursday May4 - 11.No explanation just that the flight was cancelled. Tried to give us a flight Saturday May 6 to Sat May 13 but told them to go scratch. This is the second time they have cancelled our flight in 2 trips to Cancun. We have condo reservations Thursday to Thursday, we have people that have to work on Friday the 12th and they just assume they can switch you like it's nothing. We cancelled our flights, requested a refund and booked Continental Thursday May 4-11. So it all worked out in the end. Just needed to vent about them they really pi--ed me off. We will never be flying that airline again.
