Never used it before - will NEVER use it again. Had reservations to BZE, nonstop leaving DFW on American. I just received an e-mail today saying my itinerary has changed: I now am supposed to fly to Miami on American, sit there for 2 hrs and then fly to BZE; same thing on the way back. So what was a 2 1/2 hr flight from DFW for me has now turned into a 5 1/2 hr trip. Anyone ever had this happen and do you know if it will do any good to b---- at Priceline or American?
