A few years ago I was flying from a south Florida airport to Rochester, NY. About half way there, an old couple complained to the Flight Attendent that they were supposed to go to Rochester, Minnesota to the Mayo Clinic. I checked their ticket (this was when we still had printed paper tickets) and sure enough the ticket spelled out Rochester, Minnesota, but the flight number that we were on. Interesting, because my airline did not even fly to Rochester, Minnesota.
