I did the STL-ORD commute for a couple years. It's not as easy as one might think. There's lots of flights but they're all oversold for the most part. Add in some weather in Chicago and it's a nightmare with cancelled flights, ground stops and every other commuter trying to get to work. Since you're going to be commuting on AA/UAX you don't have any priority on the jumpseat. If things started melting down I tried to go to MDW on WN or just commuter caused it and went home.
STL-EWR/LGA was way easier in terms of getting on flights. Nearly always got on.
Congrats on getting on with UAL!
