I'm going to continue a conversation started on airliners.net, regarding O'Hare expansion under a Rahm Emanual regime. The thread is here:

To respond to that forum requires a sign up fee of either $5 monthly or one-time $25. Although the material is interesting to read, I don't see me paying money just to respond to a post. If anyone has an account over there, perhaps they can cross-post.
Essentially, the responders at the forum mentioned above believe that the Western terminal should be built and given to United, and American can move to terminal 1. Other posts talk about their idealized version of O'hare, and also a lot of talk about what to do about terminal 2.
According to the OMP, the western terminal would have 8700 sq ft of apron frontage. Currently, UA and Star Alliance using all of terminal 1, and the majority of terminal 2, save for 8 gates used by Delta and Jet Blue. Combined apron footage is approximately 11,600 sq ft (1: 7259sqft, 2: 4436sqft). This would mean that the western terminal wouldn't be big enough for United and its Star Alliance partners.
I had a post
_here_ that envisions creating a terminal 4 where the HVAC building is currently located. It looks doable. You could move Delta and Jet Blue over there, and maybe some other airlines from terminal 3 onto terminal 4. Then United can take the rest of terminal 2, and AA could fill more of terminal 3.
United would be left with an interesting situation. Delta would have a newer terminal at O'Hare, and United probably understands that terminal 2 would need to be revamped. United would probably insist that Chicago come up with some money to help rebuild terminal 2, considering that a new terminal was just built for Delta. Coming up with a rebuilt terminal 2 would be ideal for United, without the need of the western terminal. This scenario would restrict the total capacity since the western terminal isn't built, but would probably leave UA and AA happier.
