Unlike O'Hare's four separate terminals, Midway is a single terminal building split into three connected concourses — A, B and C. Once you're past security, you can walk to any of them without a shuttle, train or second checkpoint.
Southwest Airlines operates the large majority of flights at Midway, mainly from Concourses A and B, while other carriers generally use the smaller Concourse C.
How Midway's Layout Differs from O'Hare's
If you're used to O'Hare, Midway is a genuinely simpler airport to navigate. There's one terminal building rather than four separate ones, and all three concourses connect after a single security checkpoint.
There's no shuttle train, no walking outside and no need to re-clear security simply to reach a different concourse.
Curbside pickup and drop-off both happen at the same terminal building, generally separated by level rather than by concourse.
For detailed ground transportation instructions, use:
If you're unsure which concourse your flight uses, your boarding pass or airline app is the most current source.
Concourse A
Concourse A is one of Midway's two larger concourses and primarily handles Southwest Airlines flights.
It also includes food and retail options and sits on one side of the terminal after passengers pass through the central security area.
Concourse B
Concourse B is Midway's largest concourse by gate count and handles a large portion of Southwest's schedule.
If you're flying Southwest, there's a good chance your flight may use Concourse A or B.
Concourse B connects to the other concourses through Midway's central post-security area, so moving between them is a walk rather than a terminal transfer.
Concourse C
Concourse C is the smallest of Midway's three concourses and generally serves airlines operating a smaller share of the airport's overall schedule.
Because Southwest accounts for most Midway traffic, Concourse C can feel less busy than Concourses A and B.
Always confirm your actual gate and concourse on your boarding pass, since airline and gate assignments can vary.
Getting Between Concourses and to Your Gate
- All three concourses connect after security. You can walk between A, B and C without leaving the secure area.
- Midway is compact compared with O'Hare. There is no internal terminal train required for normal concourse movement.
- Pickup and drop-off use the same terminal building. Arrivals and departures are separated by airport roadway and level rather than by separate passenger terminals.

One terminal makes Midway easier to navigate
Midway's single-terminal, three-concourse layout removes many of the terminal-transfer issues travelers encounter at larger airports. Confirm your gate before travel, then use the dedicated pickup or drop-off guide for the ground transportation side of the trip.
