Short by design
All of Midway's concourses are connected and reachable from each other. Arriving on a domestic flight, you can reach every concourse without clearing the security checkpoint again.

- Concourse A, Concourse B, Concourse C
Between the concourses
Southwest spans A and B, which is where most connections here happen. A change onto Frontier means crossing to C.
