It is owned and operated by the DuPage Airport Authority, which is an independent government body established by law by the state of Illinois.

In 1941, the U.S. Navy requisitioned DuPage Airport, built brick hangars, paved two runways in an “X” pattern and began training pilots for the war effort.

The post-war boom saw a lot of regional growth and the airport reflected it by adding an east-west runway and a five-story control tower and making plans for further expansion.

Surrounded by houses, restaurants and other small businesses, Midway found itself unable to expand and neighbors filed an endless succession of noise complaints.

The airport has a Fixed-Base Operator offering fuel and aircraft parking, de-icing, catering, and lavatory services.

For the 12-month period ending December 31, 2019, the airport had roughly 133,000 aircraft operations, an average of 364 per day: 95% general aviation, 4% air taxi, and <1% military.

A 1995 Chicago magazine exposé called it "A Monument to Lavish Spending of Taxpayers' Money, a Haven of GOP Patronage, and the Target of a Federal Probe."
