How early should I get to the airport for a domestic flight? The TSA recommends getting to the airport two hours before a domestic flight, but there are certain factors that could influence whether you should leave earlier or later to catch your flight.

For a domestic flight in 2026, the general recommendation from the TSA and airlines is to arrive at the airport at least two hours before your scheduled departure time. This 120-minute window is usually sufficient to handle checking bags, navigating security lines, and reaching your gate before boarding begins (typically 30–40 minutes before takeoff). However, "enough" can depend on the specific airport and time of day. At major hubs like Hartsfield-Jackson Atlanta or Chicago O'Hare during peak morning or holiday periods, two hours can feel tight if security lines are long. Conversely, if you have TSA PreCheck and are not checking a bag, you might find that 90 minutes is more than enough. If you are traveling through an airport prone to delays or if you are checking oversized equipment, sticking to the full two-hour rule—or even adding an extra 30 minutes—is the safest way to ensure a stress-free start to your trip.
