Official map
Kansas City official terminal map — airport authority website
Maps are updated when terminals are renovated or new concourses open. Terminal 5 at LAX, for example, has been closed since October 2025 for reconstruction — always confirm your terminal from your boarding pass rather than relying on a saved map.
Here is what each terminal or concourse at MCI handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Gates A1–A20. Serves Southwest Airlines, American Airlines, Alaska Airlines, and Frontier Airlines. West side of the new single terminal (opened February 2023). Southwest and American are the heaviest operators.
Gates B40–B69. Serves Delta Air Lines, United Airlines, and Southwest Airlines. East side of the new terminal. Network carriers plus Southwest overflow. Dedicated security checkpoint for Concourse B.
Two moving walkways connect Concourses A and B within the single new terminal building (opened Feb 2023). Allow approximately 5 minutes for the cross-terminal walk between checkpoints. CLEAR enrollment is on-site Mon–Sun 6 AM–6 PM.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at MCI — wait times for people-movers, buses, or security re-screening add up faster than the physical distance suggests. Build the buffer into your Leave-By time, not your gate arrival time.
Use the checkpoint that matches your gate's concourse letter — Concourse A checkpoint or Concourse B checkpoint — and verify on your boarding pass before joining a line. The new 2023 single terminal is dramatically more efficient than the old 3-terminal layout; even during the 5–8 AM and 4–7 PM peaks, enrolled PreCheck travelers typically wait only 3 minutes.
A few habits that prevent last-minute sprints:

Look for departure boards throughout the terminal for real-time gate information.
