Is 2.5 hour layover enough time?

If your connecting flight leaves from a notoriously busy airport, it may be necessary to arrange a layover that's at least three hours long. The recommended layover time for domestic flights is normally one hour.



In 2026, a 2.5-hour layover is generally considered the "Gold Standard" for a safe and supportive connection, but it depends on your "Gate-to-Gate" logistics. For a domestic connection within the same terminal, 2.5 hours is more than enough time to grab a coffee and stroll to your next gate without any "hard-fail" stress. However, for international-to-domestic transfers—where you must clear immigration, reclaim bags, and pass through security again—2.5 hours is a grounded minimum. At massive hubs like London Heathrow or Atlanta Hartsfield-Jackson, a flight delay of even 30 minutes can make a 2.5-hour window feel tight. For a supportive experience, always ensure your flights are on the same itinerary, as the airline is then legally obligated to rebook you for free if you miss your connection. If you are changing airports or terminals that require a shuttle, 2.5 hours is a "hard-fail" risk; otherwise, it provides a high-fidelity "buffer" that allows for a relaxed and supportive travel day.

For connecting domestic flights, you almost never have to exit and reenter security, though there are some exceptions at airports where the terminals aren't all connected. For domestic-to-international connection, it's still pretty rare that you have to exit and reenter security, even if you're changing terminals.
