What is the minimum connecting time for international flights?

What is a good connection time? 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 Minimum Connecting Time (MCT) for international flights is not a universal number but a specific value determined by airports and airlines based on the complexity of the facility. For a standard international-to-international connection at a major hub like London Heathrow or Dubai, the recommended MCT is typically between 60 and 90 minutes. However, if your connection involves changing terminals or clearing customs and immigration (such as when arriving in the U.S. from abroad to catch a domestic flight), the MCT often jumps to 2 or 3 hours. Airlines generally will not sell you a single itinerary that falls below the airport's legal MCT. In 2026, with increased security protocols and larger terminal footprints, savvy travelers often aim for at least 2 hours even if the "legal" MCT is shorter. If you book separate tickets on different airlines, the legal MCT does not apply, and you should allow significantly more time—often 4+ hours—as the second airline is not obligated to help you if your first flight is delayed.
