I have found a flight on Expedia that the airline site is not showing. I called the airline and was told Expedia buys a bulk of tickets and they may have something available that the airline does not. That being said, it seems like I remember someone saying if there is a problem at the airport with your ticket, that you have no recourse except to try and call Expedia since you bought it from them and the airline will not be willing to help you at all. Does anyone know of any problems using Expedia?
