Okay, I'll guess I'll tell mine.
Last summer in '08, Foch and were went on a school trip to Italy. We had sent the check in for EF(company that sponsered the trip). Unfortunately, since we have the same birth date. EF thought we were the same person and cancelled our tickets. By the time we had the problem solved, it was too late to be on the same flight as the rest of the group, so we had to book another flight with one of the chaperones, since we would've gotten lost. On the day of our flight, we were informed that it was cancelled, as their were not enough people for the flight. Our chaperone had to talk to the airline to get another flight for an hour while we drove to Logan. This, of course, wasn't helped by the transmission of the minivan going out.
The only other hassle on the flight to Milan was that it wasn't direct. We had to take a plane to La Guardia, then Dulles, then Frankfurt, then Milan.
The way back went okay until we got to Dulles. There, the flight was delayed for several hours. Then, it was cancelled as we were in the seats. I think everybody on the flight could hear the F-bomb I dropped. We had to stay in a hotel for a night before leaving on a flight to Bradley, where we found out our luggage was sent to Logan.
So for being so long, but it was a pain in the @ss.
