I swear on all that's holy that I first tried to search the forums for every imaginable keyword because I'm sure I've seen this answer before:

I'm flying out of ORD tomorrow night and it's not a regular airport of mine. Where would I tell the Uber to drop me off at departures so that I'm right near the GS reception? I thought I remembered it was pretty far down the terminal?

Thanks all, first flight since March.
