Terminal T hosts 8 airlines across 40 gates.
All 40 gates now sit behind one central checkpoint
Since February 2023, Kansas City International runs on a single Terminal T with one consolidated security hall feeding roughly 40 gates in a long horseshoe. Air Canada, Alaska, American, Delta, Frontier, Southwest, Spirit, and United all share this same secure area, so every connection stays airside. Most check-in counters line up on the departures level above the roadway; once you clear security, you hit a central node and then walk left or right along the curve to your gate.
Morning security between 5:00 and 7:00 a.m. draws the longest complaints, with Reddit users saying the standard line can stretch nearly back to the entrance doors. TSA PreCheck and CLEAR each have dedicated lanes in this central checkpoint and usually move noticeably faster in that early bank. Regulars now treat MCI like a normal medium hub and show up about 90 minutes before departure instead of the old 45‑minute slip‑in routine.
The concourse walk from one end of the horseshoe to the other clocks in around 10–12 minutes at a normal pace, according to locals who timed it. There’s no train or moving walkway; you just follow the curve past roughly 40 gate podiums. If you’re on a tight 30‑minute connection and land on one extreme while departing from the other, that end‑to‑end walk plus a bathroom stop can eat almost your entire buffer.
Gate hold rooms near clusters of Southwest departures see the worst crowding, with reports of people sitting on the floor when two or three flights push within 30 minutes of each other. Seats with built‑in outlets go fast in those busy zones. For quieter space, employees on Reddit recommend walking past the final active gates at either end; there are still rows of chairs out there but far fewer people pacing around.
Power access is generally better than in the old terminals, but it’s not uniform. Multiple travelers point to the high‑top tables in the central post‑security node as the easiest place to find free outlets and USB ports. Down at the gates, families tend to cluster around the limited in‑seat plugs, so you may end up on the floor near a wall jack if you wait too long to charge.
Restroom traffic follows the art. The most visible installations sit near the middle of the concourse, and the nearby bathrooms pick up the heaviest lines. Reddit locals suggest using the restrooms down short side corridors closer to the end gates instead; those off‑main‑path locations often have open sinks and stalls even during the morning rush.
Outside the terminal, drivers still adjust to the rebuilt access roads and elevated curbs. Some early users reported overshooting the correct level for departures or arrivals and having to loop once more around the MCI access road, which can add 10–15 minutes in bad traffic. Frequent flyers ask friends and rideshares to drop them near the center doors rather than at the far ends, which cuts down on the chance of a long indoor hike if the gate assignment shifts late.
One last tip: if you’re connecting in T on separate tickets, treat any layover under 60 minutes as tight and avoid booking self‑connections that require changing airlines across the horseshoe unless you’re comfortable with a 10‑ to 12‑minute power walk.
