How long does it take to board a connecting flight?

Travel advisers say there's a lot to take into account when booking connecting flights, but a general rule of thumb is 60-90 minutes between domestic flights and at least two to three hours for international itineraries.



The time it takes to board a connecting flight depends on the "Minimum Connection Time" (MCT) of the airport, but typically, the physical boarding process begins 30 to 45 minutes before departure. For a stress-free connection in 2026, you should allow at least 60 to 90 minutes between flights for domestic-to-domestic connections and 2 to 3 hours for international connections. If your first flight is on time and your connection is in the same terminal, you can usually reach your next gate in 15–20 minutes. However, if you must change terminals, clear security again, or pass through customs and immigration (common when entering the U.S. or the Schengen Area), the process can take much longer. Most airlines close the gate 15 minutes prior to departure, so even if you land "on time," you actually have much less time than your itinerary suggests. To avoid being "bumped," always check the gate number on your airline's app the moment you land, as gate changes are frequent in busy hubs.
