Airport Connection Time Guide
Connection time is the time between your scheduled arrival and the departure of your next flight. Whether a connection is comfortable depends on the airport, terminals, itinerary, airline procedures and what happens on the day of travel.
There is no universal safe connection time
A connection that works at one airport may be difficult at another. Walking distance, terminal transfers, security procedures, immigration, customs and baggage requirements can all affect how much time you need.
Check both flights before you travel
Look up the arriving flight and the onward flight separately. Knowing the planned arrival terminal and the next departure terminal can help you understand whether a transfer between airport areas may be required.
Domestic and international connections can be different
International itineraries can involve immigration, customs, baggage collection or another security screening depending on the airport and route. Follow the airline and airport instructions for your specific itinerary.
Your connecting gate can change
The next gate may change while your first flight is in the air. Recheck the onward flight after landing rather than relying only on a gate you saw before departure.
What if the first flight is delayed?
Compare the updated arrival information with your next flight’s current status. If the connection becomes tight, proceed toward the confirmed gate and contact airline staff for assistance when needed.
What if the flights are on separate tickets?
Separate-ticket trips can involve different baggage, check-in and rebooking responsibilities. Confirm the requirements with the airlines involved and allow for the possibility that you may need additional time between flights.
Before choosing a connection
Review the airport layout, terminal information and the airline’s itinerary requirements rather than relying on one universal connection-time rule. On travel day, keep checking both flight status and gate information.

What Travelers Should Know
Connection time is more than walking
A connection can involve deplaning, terminal transfers, security, immigration, customs and transportation between concourses.
Airport layout matters
The same number of minutes can be comfortable in one terminal and difficult at a large international hub.
Before booking a tight connection
Review the airport layout and whether the flights use the same terminal. Separate tickets can add baggage and rebooking risks.
Frequently Asked Questions
How much connection time do I need at an airport?
It depends on the airport, terminals, itinerary and whether you must clear security, immigration or customs. Use the airline's minimum connection time as a starting point and allow extra time when possible.
Does changing terminals increase connection time?
Usually yes. A terminal change can require a long walk, train, shuttle or another security process depending on the airport.
What should I do if my connection becomes too tight?
Check the onward gate immediately and contact the airline if the inbound delay puts the connection at risk.
