O'Hare and Midway
Chicago is home to two major airports, O'Hare and Midway. Midway is a hub for Southwest while O'Hare is a hub for United and offers several international airline carriers. The best part? Both can be directly accessed to/from the city via public transportation. The Blue Line runs directly to O'Hare and the Orange Line to Midway.
