Transportation in Chicago - Airports

Airports

• O'Hare International Airport, which is the second busiest airport in the world by one measure, is a major airport serving numerous domestic and international destinations. It is a hub for United Airlines and American Airlines. Construction is underway for a major expansion. This airport is statistically one of the busiest in the United States.
• Chicago Midway International Airport serves primarily domestic destinations. It is a major focus city for Southwest Airlines.

There are several minor airports in the Chicago area with either limited or proposed commercial service. These include:

• Gary/Chicago International Airport in Gary, Indiana, located about 25 miles from the Chicago loop. Gary/Chicago is operating as the "third airport" for the Chicago area. While Gary/Chicago Int. Airport's current operations include just one scheduled commercial passenger service, it is currently undergoing facility improvements, and the administration is courting airlines aggressively. Boeing and White Lodging Services already base their corporate fleets here. The National Guard has constructed facilities to base their Chicago metropolitan area air operation here as well.
• Chicago Rockford International Airport in Rockford, which supports scheduled airline service to Denver, Cancun, Punta Cana, West Palm Beach, Punta Gorda, Las Vegas, Orlando-Sanford, Phoenix/Mesa, and St. Petersburg/Clearwater. Rockford officials are positioning the airport to attract customers from Chicago's western suburbs.
