Chicago O'Hare International Airport (KORD / ORD) is one of the busiest airports in the world and a primary connecting hub for the U.S. interior.

O'Hare is one of the busiest connecting hubs in the U.S. and sits in the middle of the country's main weather corridor. Snow, thunderstorms, and low ceilings at ORD ripple outward and frequently delay flights nationwide.
