About security at MDW

Chicago Midway International is Southwest Airlines' second-busiest hub, processing over 20 million passengers per year through a compact single-terminal layout. Unlike O'Hare's sprawling multi-terminal setup, Midway's three security checkpoints (A, B, C) all feed the same concourses, making checkpoint choice more flexible.

Best time to arrive at MDW

Peak hours: 5–8 AM and 3–7 PM on weekdays; Friday evenings and Sunday afternoons are the worst of the week as leisure travelers dominate the schedule
Recommendation: Checkpoint A (near the main entrance) gets the longest lines because it's where most passengers head by default. Checkpoint C, located near the food court on the west side, is consistently the fastest — most travelers don't know it exists. Worth the extra 3-minute walk.
PreCheck tip: TSA PreCheck is available at all three checkpoints. Checkpoint B tends to have the shortest PreCheck queue during peak hours because it's the middle option that passengers bypass in favor of the main entrance.
