To PMNW phone agents, Rochester tended to mean the one in Minnesota so I always was careful to clarify that my tickets were to the right place.

If I'm tired or not completely awake when boarding, I always verify the destination with the FAs in front. Sometimes they seem to like to joke around about it a bit, but this rarely really scares me.

I've also heard pilots announce the wrong destination, including that we would be flying to our current location when the aircraft apparently does a quick turn.
