About Chicago
Chicago is the great American city that the coasts overlook - a dense, architecturally extraordinary lakefront city with world-class museums, deep-dish pizza, and jazz and blues venues that trace the music's northern migration. O'Hare (ORD) and Midway (MDW) together give the city one of the world's widest airport choices.
