I have very fond memories of flying through STL in the mid-to-late 80's. Even though I've flown 1.6MM with UA, the only lounge in which I've ever been greeted on sight by name was the Ambassador Club at STL. Even when there was a long line, Lois would see me, call me by name and tell me just to go in, have a seat, and make myself comfortable. Everyone on line would turn to see who this 'important' person was, and when they saw a 27 year old kid walk by (albeit in a suit and tie, this WAS the 80's after all), I would get the strangest looks. Seeing STL in UP IN THE AIR brought back a lot of those memories for me.
