Officially opened in 1955, the airport is named after Lt. Cmdr. Edward H. "Butch" O'Hare, a U.S. Navy war hero. On baggage tags, the ORD is an abbreviation of its original name: Orchard Place Airport.
Once exclusively known as the "world's busiest" airport, O'Hare now trades that title with Atlanta's Hartsfield Airport. Yet more than 200,000 travelers pass through the nearly 7,700-acre, 172-gate facility daily and the airport claims to offer more flights to more cities, more often than any other in the world.
Travelers can conveniently get around the airport via the Airport Transit System, which is a free, 24-hour train that operates between the three domestic terminals, the international terminal, long-term parking, and the Metra train station.
The CTA's Blue Line, located at the lowest level of the main parking garage, is the best option for getting downtown. Trains depart approximately every 10 minutes, 24 hours a day. A variety of shuttle services and cabs are available for transportation to the city and suburbs.
