Chicago Midway International Airport's history
Chicago Midway International Airport (MDW) is a major commercial airport located on the southwest side of Chicago, Illinois. Established in 1927, Midway served as Chicago's primary airport until the opening of O'Hare International Airport in 1944.
Originally named Chicago Air Park, Midway Airport was built on a 320-acre plot in 1923 with a single cinder runway, mainly for airmail flights. In 1926, the city leased the airport, and on December 12, 1927, it was named Chicago Municipal Airport. By 1928, the airport had expanded to twelve hangars and four runways, which were lit up for night operations. However, a major fire on June 25, 1930, destroyed two hangars and 27 aircraft, causing a loss of over two million dollars.
In July 1949, the airport was renamed Chicago Midway International Airport after the Battle of Midway. That year, Midway handled 3.2 million passengers, and by 1959, passenger traffic peaked at 10 million. However, the airport's proximity to surrounding buildings hindered its expansion plans, and it struggled to accommodate larger four-engine jetliners introduced in 1959.
Reconstruction efforts began in 1967, adding new concourses, gates, and ticket counters. In 1968, the city invested $10 million in renovation funds, attracting major airlines back to Midway. Southwest Airlines began operations at Midway in 1985 and has since become the airport's primary carrier, handling over 90% of its passenger traffic.
The terminal complex was completed in 2001, featuring 43 gates and facilities for international passengers. The Chicago 'L' Orange Line, launched in 1993, connects Midway Airport to Downtown Chicago and other rapid transit lines. The airport continues to undergo enhancements, including the addition of a new walkway and food court in Concourse A during the 2010 expansion project.

The Battle of Midway
Midway International Airport (IATA: MDW) in Chicago, Illinois, is named after the Battle of Midway, a World War II naval battle fought between the United States and Japan. The battle, which took place from June 3 to June 6, 1942, was a pivotal moment in the war and had a significant impact on the course of the conflict in the Pacific.
The US commander of the Pacific Fleet, Chester Nimitz, sent a large force under Frank Jack Fletcher to the Midway area before the Japanese arrived. On June 4, land-based planes from Midway and carrier-based planes from the US fleet launched a surprise attack on the Japanese force led by Vice Admiral Chūichi Nagumo. All four Japanese fleet carriers present—the Akagi, Kaga, Sōryū, and Hiryū—were sunk, along with the heavy cruiser Mikuma. Japan lost 3,000 men, including many well-trained pilots who were challenging to replace. In comparison, the US lost the carrier Yorktown and the destroyer Hammann.
