Tomorrow we're flying to Cancun from DFW via ORD. Arriving ORD (gate B5) at 8:02 AM. Depart for Cancun 1 hour, 8 minutes later (no gate given yet, just told International ). My wife has an injured foot and I've requested a wheelchair. Two questions: (1) Assuming ORD is relatively on time, should we be okay? (2) What's the fastest way to get to the International terminal from B5? Thank you!
