What to know
Chicago Department of Aviation terminal map lists Spirit at ORD. Terminal operations can move during construction, irregular operations, or seasonal schedule changes.
Airport layout
O'Hare currently uses Terminals 1, 2, 3 and 5. Terminals 1 through 3 connect after security; Terminal 5 is reached by the Airport Transit System or eligible transfer bus.
Getting to the gate
International arrivals without U.S. preclearance generally process through Terminal 5 even when the airline departs from another terminal.
Connections
Allow extra time for a Terminal 5 connection because many transfers require another security screening.
