I had my whole flight lost on me one day. I had just flown in to Philly and my connecting flight to Corning was at gate A7 (or whatever the terminal said). I proceeded to that gate and found the gate completely empty and nothing on the monitor. I waited until it was about ten minutes before boarding time and still crickets. I walked to another gate and asked the agent behind the counter about the flight. A bunch of tapping and they said there wasn't any record of that flight and that they couldn't help me. Uh, ok... I next went to the customer service desk, and the agent there did a bunch more tapping and finally said, "oh, here, the gate is H1". Where the heck is H1? "It's that brown building on the other side of the runway, you can see through the window". The hanger?? "Uh... yes." Huh? "<shrug>". I finally went out through security and into the ticketing line and said, "I don't know what is going on, but can I get a seat on the next flight going to Corning?" The agent had a heck of a time trying to cancel my ticket, as it kept telling them there was no ticket even though they could still bring it up on screen. Finally a supervisor figured it out. Somebody had cancelled the flight, moved everybody to other flights, and then killed the flight record. For some reason, my ticket was still booked on a now non-existent flight, and that confused the hell out of the system and made it give weird info (such as the flight was in the hanger, or that my ticket didn't exist). The supervisor had to re-create the flight, move my ticket off it, and then delete the flight again.
