AA is "isolating" the O'Hare hub operations so that its delays won't interfere with the reliablility and effectiveness of the rest of the system. Basically, aircraft flying from ORD to a destination will turn around and fly right back to ORD rather than flying to another hub. Example. ORD-LGA-DFW will now be ORD-LGA-ORD and the aircraft won't be necessary for connections in DFW.
What do you think?
I think this is great and should have been thought of much sooner.
