I know it's some way off yet, but next May my wife and I are flying from ORD to LAS on UA108 that departs at 4.55pm.

But her's the deal, she's flying in from LHR on UA949 that arrives at 3.20pm and I'm flying in from BOS on UA537 arriving at 3.25pm.

My wife has regularly done INT-DOM at SFO and LAX but never at ORD. Can someone advise what's the INT-DOM xfer process involve at ORD and what would be the best suggestion for meeting up in the airport other than at the gate for the LAS flight. Obviously at this point in time we hae no idea which concourse the LAS flight would be departing from.

Thanks in advance for any tips and advice.
