Walking between concourses
For a tight connection: roughly how long the walk is from the middle of one to the middle of the other, at an easy pace with a carry-on. Some terminals only connect by train or bus even when they look close, so follow the airport’s signs, and add time if you have to go back through security.

Flying through ORD?
Gates move, and a connection that looked comfortable at booking can shrink to twenty minutes after a late departure. TripTidy puts your gate on this map with you on it, tells you how long the walk is to your connection, and pushes the gate change the moment it happens, often before the airline’s own email. It builds the trip from your booking emails, so there’s nothing to type.
