AD PLACEMENT — CONTEXTUAL
The new single-terminal layout means once you're through security, every gate is reachable on foot within about 10-15 minutes.
If you're arriving from an international flight, budget extra time for Customs and Border Protection processing and a security recheck.
MCI is not a congested hub, so lines at security checkpoints are usually short even during peak morning and evening waves.
Signage in the new terminal is clear and gate numbers are logically arranged, making self-navigation easy without needing airport staff assistance.
Because MCI serves relatively few true hub connections, allow a bit of buffer if your flights are on different airlines with separate check-in requirements.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
The new terminal is a single unified building with two connected concourses (A and B) branching from a central hub area, so all transit is on foot with no train or shuttle required. There is no need to re-clear security for domestic-to-domestic connections since it's a single post-security zone, but international arrivals must clear Customs and Border Protection and recheck bags/security before continuing to a connecting flight.
