There were three of us on the plane headed to the wrong destination. None of us knew each other. This was in 2004. My ticket wasn’t scanned, just handed to the gate agent. I was supposed to go from Atlanta to Houston and they were hurrying us because flights were winding down for the night. This was about 10:30 pm. I ended up having to spend the night in Tampa on the airlines dime, then had to fly back to Atlanta the next morning to connect to Houston. It was on Continental Airlines.
The bad thing was I was headed to Houston in a rush to attend to a family member who had had a medical emergency.
I almost got on the wrong Bus once. Does that count?
