How long you actually need between flights at the big hubs
Minimum connection times at 45 major hub airports, split by connection type, with the layout and immigration quirks that make each one faster or slower than the number suggests. The minimums are what airlines will sell you — the "book at least" column is what to give yourself. Every figure is approximate: published minimums differ by airline, terminal pairing, and season, so treat this as a planning guide and confirm the exact minimum with your carrier.
All figures assume one ticket with bags checked through. On separate tickets you re-check bags and clear security again — allow three hours anywhere, four at the red hubs.
The slow step is almost never walking — it is passport control. Any connection that crosses an immigration border (Schengen boundary, US or Canadian entry, terminal-change re-entry) needs the higher number.
If you miss a connection on one ticket the airline rebooks you free. Miss one across two tickets and the second flight is simply gone — that gap is the whole reason to overbuy time.
Last flight of the day, one bag, tight budget: buy the longer layover. The cheapest itinerary is usually the one with the shortest connection for a reason.
Nothing matches your search.

One terminal, one security zone, and the shortest published minimums of any major European hub. The only real friction is the Schengen border between the D piers — cross it and you queue at passport control. Gates in the far H/M pier are a 15-minute walk from the centre.

The efficient alternative to Frankfurt on the same network. Terminal 2 and its satellite handle almost all connecting traffic and are linked by an underground train that runs constantly. Consistently makes short connections work where Frankfurt does not.

Compact, well-signed, and reliably fast. The E gates used by long-haul flights sit across the runway and are reached by an underground train — allow ten minutes for that leg, plus passport control if you are crossing the Schengen boundary.

Built specifically as a short-connection hub between Europe and Asia, and it shows — one compact terminal, minimal walking, and among the lowest minimums in Europe. Long-haul Asian routes now fly around Russian airspace, so inbound delays are more common than they were.

One of the shortest published minimums anywhere. The terminals are joined airside and the walk from the F gates to the D gates is a few minutes. A genuinely good place to route a tight Central European connection.

Same-terminal is 60 minutes and works; anything crossing terminals is 90 and often needs it — T3 to T5 is a bus or a long transit ride plus a second security screening. Terminal 5 is self-contained and by far the easiest for British Airways connections. Assume delays: Heathrow runs at capacity almost every day.

Lufthansa raised the standard minimum here to 60 minutes in 2025 after the old 45-minute exceptions kept failing. Frankfurt is very large: Terminal 1 alone runs A through Z concourses, and a Z-gate long-haul arrival to an A-gate departure is a real walk plus passport control. Munich is the faster hub on the same network.

The main gateway between Europe and Latin America. Terminal 4 and its satellite T4S are connected only by an underground train — long-haul arrivals land at T4S and most European departures leave from T4, so budget 20 minutes for that transfer alone. A T1/T2/T3 connection means leaving security entirely.

Terminal 1 is straightforward and handles nearly all connecting traffic. The trap is a T1–T2 connection: the terminals are 4 km apart with only a landside shuttle bus, so that pairing needs closer to two hours regardless of the published minimum.

Enormous — one of the largest terminals in the world under a single roof, and a gate-to-gate walk can genuinely take 25 minutes. Turkish Airlines runs dedicated short-connection transfer desks at the concourse ends for tight cases. Anything involving the domestic pier needs the full 75 minutes.

Normal European connections are easy. The one to plan carefully is a US-bound departure: Dublin has full US preclearance, so you clear American immigration and customs in Ireland. That is a real border crossing with real queues — give it two hours and you land in the US as a domestic arrival.

The busiest airport in the world and, for domestic connections, one of the most efficient — every concourse sits on one underground train line, so 35 minutes genuinely works (45 if you arrive on a widebody). The asymmetry is the point: arriving internationally means immigration, baggage re-check, and a second security screening, which is why that number triples.

Domestic connections within Terminals 1–3 are fine and airside. Terminal 5 handles most international arrivals and, until recently, had no airside link — check whether your pairing requires the ATS train and a re-clear of security. Winter weather makes O'Hare one of the least reliable US hubs from December to March.

Five terminals in a ring, all linked airside by the Skylink train, which runs every two minutes and reaches any terminal within nine. That design makes DFW one of the more forgiving large US hubs — the distances look alarming on a map and are not a problem in practice.

A single very long horseshoe terminal — the walk from the D gates to the J gates is close to 25 minutes even with the Skytrain. Immigration halls here handle enormous Latin American banks arriving together; the published 90 minutes for an international arrival is a floor, not an average.

Compact by US standards and the international terminal connects airside to Terminals 1, 2, and 3 for departing passengers. The real hazard is not the building — it is summer fog, which routinely cuts arrival rates and makes SFO one of the most delay-prone US airports.

The world's busiest international airport, and the scale is the problem rather than the process. Terminal 3 alone has three concourses linked by an underground train, and an A-gate to C-gate move plus connection security is a solid 30 minutes. A Terminal 3 to Terminal 2 connection (flydubai) is a different building entirely — treat it as a separate airport.

Regularly rated among the world's best airports and same-terminal connections are effortless. The catch is that Terminal 1 and Terminal 2 are 15 minutes apart by shuttle bus — Korean Air and its partners use T2, most other carriers T1, so an interline connection frequently means a terminal change.

The international Terminal 1 sits on the opposite side of the runways from the domestic Terminals 2 and 3 — the transfer is a bus or the T-Bus shuttle and takes 15–20 minutes on top of immigration, customs, and Australia's strict biosecurity screening. That last step is slower than travellers expect.

The international and domestic terminals are separate buildings roughly a 10-minute walk or free shuttle apart. New Zealand biosecurity is among the strictest anywhere and inbound bag inspection is thorough — that, not the walk, is what fills the 90 minutes.
