Flying a 767 Atl-Las........36+ ppl on upgrade list......I'm DM and was #2........on a SDC.......I boarded and door closed. The seat next to me stayed empty, in FC. I was very surprised cause of the huge UG list. Then a FA brought up a passenger from coach to fill the seat. I figured he was the guy at the cutoff of the UG list. A GM or FO.......but no.......he was an employee of another airline. Didn't bother me at all. Im just curious why this was done instead of the next person on the UG list.

Again, I got my UG, so no complaints from me. Just an observation and was curious about it.
The FA's were all fantastic by the way
