I'm flying to Chicago in a few weeks to meet up with some friends who are also flying in.

I'm flying in on Delta (Terminal 3?)

My friends are flying in on British Airways from London (Terminal 5?)

It'd be best if we could arrange a place to meet before hand, as they will have to pay international roaming rates to call me on my cell phone.

Any easy suggestions on where we can aim to meet up? They land about 1 hour before I do, but they have to deal with customs.

We are taking the El into the city. So perhaps something along one of our routes from our various terminals to the train that has chairs to wait at.

Thanks for any suggestions,
Duane-O
