Flying from Chicago O'Hare
Chicago O'Hare is one of America's two busiest hubs and the home base for both United and American — Terminals 1 and 2 belong to United, Terminal 3 to American, and Terminal 5 handles all international arrivals. The CTA Blue Line runs from a station at the airport to downtown Loop in around 45 minutes for $5.
