How Early Should I Get to the Airport?
Enter your departure details and we'll calculate exactly when to arrive, using real TSA wait time data from your airport.
General Airport Arrival Guidelines
The standard advice is to arrive 2 hours before a domestic flight and 3 hours before an international flight. But that rule of thumb doesn't account for your specific airport, time of day, or whether you have TSA PreCheck. A 6 AM departure at a busy hub like JFK requires a very different arrival time than a 2 PM flight from a regional airport like SAN.
Our calculator factors in real TSA wait time data for your airport, the day of week, your PreCheck status, and whether you're flying internationally to give you a recommendation tailored to your actual trip.
Peak Times to Avoid
Airport congestion follows predictable patterns. The morning rush from 5 AM to 8 AM is the busiest window at most airports, as business travelers and early departures flood check-in and security. The evening rush from 4 PM to 7 PM brings another wave of passengers.
If you can, fly midday or late evening. TSA lines are typically 30 to 50 percent shorter between 10 AM and 2 PM compared to the morning peak. Late evening flights (after 8 PM) often have the shortest security waits of the day.
Does PreCheck Help?
Yes, meaningfully. TSA PreCheck saves 10 to 20 minutes on average in the security line. You keep your shoes, belt, and light jacket on. Laptops and 3-1-1 liquids stay in your bag. The dedicated PreCheck lane typically moves faster even when there is a line.

Frequently Asked Questions
How early should I get to the airport for a domestic flight?
For most domestic flights, plan to arrive at least 2 hours before departure. If you have TSA PreCheck and are flying from a smaller airport, 90 minutes may be enough. During peak travel times (holidays, early morning rush), add an extra 30 minutes.
How early should I get to the airport for an international flight?
Arrive at least 3 hours before an international departure. International flights require extra time for check-in document verification, potential customs or immigration processing, and earlier boarding cutoffs. Some airlines close check-in counters 60 minutes before international departures.
Does TSA PreCheck save time at the airport?
Yes. TSA PreCheck typically saves 10 to 20 minutes in the security line. PreCheck passengers keep shoes, belts, and light jackets on, and laptops and liquids stay in bags. The average PreCheck wait is under 10 minutes at most airports, compared to 15 to 25 minutes in the standard line.
What is the busiest time at the airport?
The morning rush between 5 AM and 8 AM is typically the busiest time at most airports, followed by the evening rush from 4 PM to 7 PM. Midday (10 AM to 2 PM) and late evening tend to have shorter lines. Monday mornings and Friday afternoons see the heaviest business travel volume.
Should I arrive earlier on holidays?
Yes. During peak holiday travel periods like Thanksgiving, Christmas, and the Fourth of July, add at least 30 extra minutes to your normal arrival time. Airports see 20 to 40 percent more passengers on peak travel days, which means longer check-in lines, longer TSA waits, and more crowded terminals.
