Shortest Minimum Connection Times

Ranked comparison of 70 major airports by published minimum connection time (MCT). MCT is the airline-published floor for a single-ticket connection and varies by carrier; numbers here are airport-wide approximations. Compare domestic-to-domestic, international-to-domestic, and airside-connected status before booking a tight itinerary.

Quick answer

The shortest domestic-to-domestic MCTs in our dataset are AMS (25 min), DFW (30 min), DEN (30 min), ORD (30 min), JFK (30 min). For international-to-domestic, plan on at least 50 min at the fastest airports and 2 hr+ at JFK/LAX/ORD where customs bottlenecks are common.

Airside-connected: 40 of 70 airports allow all-terminal transfers without re-security
Not airside-connected: 30 require shuttle or landside transfer for some terminal pairs
American Airlines MCT: 25 min domestic at AA hubs (DFW, CLT, PHX) - the shortest published carrier standard

15 shortest domestic-to-domestic MCTs

These airports have the shortest published MCTs for domestic-to-domestic transfers. Airside-connected airports tend to cluster at the top because no re-security is required. Always pad beyond the MCT on real-world itineraries to absorb boarding and inbound delays.

15 shortest international-to-domestic MCTs

International-to-domestic connections include customs clearance and bag-recheck time (at US airports) or immigration re-entry (abroad). These times already bake in the typical customs delay at each airport.

40 fully airside-connected airports

At these airports you can transfer between any two gates without re-clearing security. This is the single strongest factor in making tight connections workable.

Frequently asked questions

What is a minimum connection time (MCT)?

Minimum connection time is the shortest interval an airline or airport will allow between an arriving and departing flight on the same booking. If your connection falls below the MCT, the flights cannot be sold as a single itinerary and you will not be automatically rebooked if you misconnect.

Which US airport has the shortest minimum connection time?

AMS Amsterdam Airport Schiphol has one of the shortest domestic MCTs at 25 min. Other short-MCT US airports include DFW (30 min), DEN (30 min), ORD (30 min), JFK (30 min).

Why is the international-to-domestic MCT longer than domestic-to-domestic?

International-to-domestic connections require clearing US Customs and Border Protection, recollecting checked bags, and re-checking them with your onward carrier. That whole process takes 30-60 minutes in addition to the gate-to-gate walk. US Customs facilities at JFK, LAX, and SFO have historically been the slowest during peak hours.

Does American Airlines have a 25-minute connection time?

Yes. American Airlines publishes a 25-minute domestic-to-domestic MCT at its hubs including DFW, CLT, and PHX. This is shorter than the airport-wide standards. The 25-minute MCT only applies at the same terminal on the same airline; if your connection crosses terminals or airlines, the longer airport MCT applies.

What happens if my layover is shorter than the MCT?

Booking engines should not allow this — they check MCT at search time. If you are booking two separate tickets (self-connecting), MCT does not apply, but you lose all airline protection: if you misconnect, you pay for a new ticket. For a single itinerary booked on one ticket, always verify MCT compliance and add buffer for real-world delays.

Which airports are airside-connected between all terminals?

40 of the 70 airports we track are fully airside-connected, meaning you can transfer between all concourses without re-clearing security. Notable examples: ATL (Plane Train), DFW (Skylink), DEN (underground train), SIN (Skytrain between T1-T3), DXB (through Concourse D). Airports like LAX, JFK, EWR, and CDG are not fully airside-connected — inter-terminal transfers may require exiting and re-clearing security.
