Q. How challenging is Chicago O'Hare to navigate? Is one hour enough time to make a connection?

A. Supposedly it is if you’re traveling to and from a United flight… but it's always a good idea to allow yourself a little extra time, especially if connecting to the last flight of the day, or if you're connecting to an international flight.

And certainly leave extra time if you’re the slightest bit mobility impaired, or make arrangements in advance for a cart to drop you directly at your connecting gate.
