I would say that it is more like AA gave up its market share instead of UA taking it away. The price of ORD is too much for the penny pinchers in Skyview 6 and they wrongly decided to stuff too much through CLT and DFW. Now it looks like they may be changing their tune a bit by opening an ORD Airbus base and slightly growing the number of pilots. But yeah, UA gladly stepped in to fill the void that AA voluntarily gave up.
