I'd be wondering why these are the only companies that you're looking at if you're hoping for an ORD base. The commute between ORD-STL isn't exactly a friendly one, well, it's not terrible going to STL, but going back home won't be much fun as there's typically a million and half people going that way, especially once you include all the other non-rev folks, and with weather issues putting chi-town in an all day delay within a few minutes, it's risky to say the least, and especially at a company without a commuter clause (aka TSA). If you're not wanting to live in STL or RIC, i'd look for a different chicago based regional, most likely excluding AE from my list as well, good luck.
