@melgallion Sorry your flight was canceled. It sounds like there was an aircraft swap which caused your flight to be canceled since it was going to Houston then instead went to Pittsburgh. Swaps happen for many reasons from staffing to weather or other planes breaking down just to name a few. I believe the airline schedules people on the next available flight as soon as they cancel the original flight that way there isn't a 100 plus person line waiting to rebook one by one. You can always talk to an agent at the airport or by phone to see what other options are available as they usually allow you to make 1 change for free. You could also try to go standby on the other flight if it leaves before your new flight in case someone no shows and a seat becomes available. Hope the rest of your flights go smoothly! Blake
