The station, along with the rest of the Orange Line, opened on October 31, 1993 after a long wait by Chicago's southwest side for 'L' access.
Unlike O'Hare , passengers using Midway station do not pay an airport surcharge in addition to the standard "L" fare.
As early as the 1940s, when subways were being constructed under State and Dearborn Streets, the city planned to expand the 'L' to Midway Airport.
Many people attended, including Mayor Daley; Bernard Ford, the CTA Acting Executive Director; and David Williams, the Chicago public works commissioner.
Midway Station includes a three-track terminal, a rail yard, a car maintenance facility, an island and side platform, elevators leading to the sidewalk, and escalators and stairs connecting to the moving walkway heading to the airport.
