i had the same issue yesterday in cmh except i wasnt commuting i was trying to work. I was going to the delta gates on the C concourse and the tsa agent asked who is chautauqua? I looked at her and was just stunned. I told her we fly for all the airlines here and practically own the place with shuttle and Republic. Thankfully one of the other tsa agents said that we fly for delta and she let me through.
