. It was once the headquarters for American Airlines
, and later became the headquarters for Midway Airlines
. Most of Midway's users today are low-cost carriers
that want to get around the hefty fees at O'Hare.
Oddly enough, American sold its hub operation at Raleigh-Durham International Airport to Midway in 1995, and Midway Airlines almost left Midway Airport altogether. So you could say that American left Midway to Midway, and then took Midway out of Midway. This left Midway midway toward a second bankruptcy.
Some people call Midway "Mayday."
