I called O'Hare and they referred me back to American Airlines... I was told I would simply need to make sure that my layover allowed me time to take them out and come back through the security checkpoints. That I don't mind at all.
The Information lady at O'hare said , well if your paying to carry them on the airlines should have made arrangements for an area your pet can go to as well. I never though of it that way...
