Hold on a second; didn't you already tell them to pound sand after a couple of days in training? If you're asking for a friend, I sure hope you've warned him or her.

Anyway, to answer your question, boiler above is correct, but that time can very wildly, and getting a line may take a bit because of a lot of CHQ/Q400 transfers yet to happen.

Bear in mind, this is as it sits...there are so many things in progress at RAH that it might change completely....there's even a good chance that S5 ORD may not exist in 12 months.
