If you are a plane geek like me, now is your chance to see the inside of Terminal 5 and get some restaurant specials on Thursday 24 Jan 2017 for Chicago Restaurant Week! I have always flown United from ORD which means I have never set foot in the departure side of Terminal 5. You can pick an entry time by registration here for terminal 5 only. If you are actually flying somewhere you can check out the specials here for the other terminals and below for terminal 5.
Might even try entry into the Air France lounge with Priority Pass!
