Chicago O Hare International Airport, IL (ORD)
The Chicago O’Hare International Airport is the largest and most important commercial airport in the US state of Illinois. In terms of flight movements and passenger numbers, it is one of the three largest in the world. Chicago O’Hare currently handles around 15% of all flight connections within the USA.
In addition to O’Hare, Chicago, with Chicago-Midway International, is also the second largest commercial airport in the state. Furthermore, in the distant metropolitan area of Chicago, there is Chicago Rockford International Airport, located approx. 140 kilometers further north-west near the city of Rockford, and approx Gary International Airport was 35 kilometers southeast of downtown Chicago (Chicago Loop), of which only a few charter flights are currently offered. Like O’Hare and Midway, Gary is administered by the Chicago Airport Authority, which is trying to reactivate Gary International as a further alternative for various low-cost carriers.

The CTA’s “Blue Line” express train runs regularly between the airport and the Chicago Loop.
Passengers who have to change between O’Hare and Midway use the “Blue Line” between O’Hare and the Transit Center in downtown and then change to the “Orange Line”, otherwise there is the possibility of various private transfer shuttles or taxis to drive.
Furthermore, numerous regional bus shuttles run from the airport to the surrounding communities in the greater area, e.g. to Crestwood, Michigan City, Mishawaka, Omega or Rockford.
The airport, which was originally commissioned by Douglas Aircraft as an aircraft yard during the Second World War, was selected and designed as the main airport for the metropolitan area of Chicago in 1955, after it had been foreseen in the previous years that Chicago Airport, which had been the main airport since 1931 -Midway was no longer able to cope with the massive growth in traffic alone. In the same year the first aircraft took off and in 1958 the construction of an international terminal followed. After all the expansions were completed in 1962, the city council finally moved all domestic air traffic from Midway to O’Hare, making it the second most important commercial airport in the United States.
