How MDW is laid out and how to move between buildings.
Terminals at MDW
Central Market
The food and shopping area after security, where Concourses A, B and C meet. The Club MDW lounge and the USO are both in this area.
Concourse A
Mostly Southwest gates, plus Frontier and Volaris. Volaris flights to Mexico leave from here, and the customs facility for international arrivals is on the lower level.
Concourse B
The longest concourse at Midway, with moving walkways. It serves Southwest, Delta, Allegiant and Avelo.
Concourse C
Connects to the Central Market at the same point as Concourses A and B. Check your gate on the departure boards, since gate assignments can change close to departure.
Moving between terminals
After security, you walk through the Central Market to reach any concourse, so there is no need for a train or a second screening. Concourse B is the longest, so allow extra time there, and use the moving walkways where they are provided.
