It may not be the largest airport in America, but Chicago O'Hare International Airport (ORD)) is once again the busiest, having surpassed Atlanta's Hartsfield-Jackson in flight traffic last year.

O'Hare has four terminals—1, 2, 3 and 5. There is no Terminal 4. (There once was a Terminal 4 for international flights but that building is now the airport's shuttle bus depot.) Among the quartet of existing terminals, Terminal 5 serves international flights while Terminals 1 through 3 serve domestic travel and are connected to each other. The largest, Terminal 3, includes four separate concourses.
