In 2026, a 1-hour transit is considered "tight" and high-risk, especially at large international hubs like Paris CDG, London Heathrow, or Atlanta. While it might be "legal" (meeting the airline's Minimum Connection Time), it leaves zero margin for error. If your first flight is delayed by even 15 minutes, you will likely miss your connection. Furthermore, 60 minutes is often not enough time for your checked luggage to be physically transferred between planes, leading to "delayed bags" at your final destination. A 1-hour connection is only feasible if: 1) You are at a smaller airport, 2) Both flights are on the same airline in the same terminal, 3) You have carry-on luggage only, and 4) You have priority/fast-track security access. For international-to-domestic connections (e.g., landing in the US from Europe), 1 hour is never enough, as you must clear Immigration, collect your bag, clear Customs, and re-check the bag. In 2026, travel experts recommend a minimum of 90 minutes for domestic and 2.5 to 3 hours for international connections to ensure a stress-free journey.
