I've had some frustrations over this entire ORD expansion over the years and thus I must vent here. I hope the cronies running the aviation department take a look at this - it seems like no one has given them any advice that makes any sense.
First, O'Hare's website is not even appropriate for a 3rd world dirt air strip. What a shame:

Second, the last 30 years has been nothing but a steady decline in O'Hare and Chicago's place in aviation. Don't tell me about Boeing. I'm talking aviation infrastructure quality. Yes Midway is nice now, but it's small and has reached its max capacity. The two global hubs, United and American, have both drastically declined. And ORD, the one long time busiest airport in the world, has now slipped from 35 years of 1st place to 4th, yes FORTH. Atlanta on the other hand handles more passengers and flights than both O'Hare AND midway combined.
Finally, this expansion project has been handled poorly by the department of aviation and its treatment of the airlines, United and American.
They keep saying nonsense about more competition via the new western terminal. The airlines do not need more competition, there is plenty of it, Southwest owns Midway, and we already pay rock bottom prices for flying.
It's all about THE HUB.
Atlanta is what it is because of Delta. It offers over 1,000 daily flights to destinations around the globe, across America, and is considered the largest hub operation. It is the single most important factor in Atlanta emerging as a global city due to the air connections.
More "competition" at O'Hare means what, jet blue giving O'Hare its 48th flight to New York City? Some cheap airline with $80 flights to Florida? Let the vacationers go somewhere else, O'Hare needs to build its hubs.
The Western Terminal should go to United. It can serve as the North American Star Alliance hub, where United and all of its international partners operate out of. United's domestic operation can expand in terminal one and take over a new terminal 2. This is a perfect opportunity with United's merger with Continental.
With Star Alliance partners out to the new western terminal, American Airlines should have all of terminal 3 for its domestic operation and all of International Terminal 5 should go to the international One World Alliance.
All left over carriers can be housed in the new terminal 6.
Businesses book airline contracts with the airline that can give them the single most non-stop connections, domestic and international, with nice business lounges, frequency, and a good frequent flier plan. Spirit airlines to Florida is not that, United and American are. Stronger United and American hubs means a stronger O'hare, period.
