ORD Terminal 5 lounge options
I just booked an Aeroplan award for the wife ATL-ORD-FRA rt, all on UA metal, for next week in J.
She'll arrive in terminal 1at ORD, where it looks like most of the United lounges are, and departed 3 hours later from terminal 5.
What would be her lounge options in terminal 5, or is it wise to stay in terminal 1?
Thank you
