You can bet on ORD. However, the recent arbitration ruling has reduced the amount of aircraft that were going to support ORD/IAD/DEN UAX operations. Therefore not as many crews needed in ORD as originally thought. But not really sure.

There's enough people that thought they were going to be displaced from IAH, and a lesser extent EWR that will now probably stay in those bases.

I'd venture to say that ORD is a safe bet.
