How the times are worked out
- Domestic: arrive 2 hours before departure, the guidance TSA and the major airlines give. With PreCheck and no checked bag, 90 minutes is usually enough.
- International: arrive 3 hours before. Document checks and earlier cut-offs set the pace, not just security.
- Holiday weeks: add 30 minutes or more. The Sunday after Thanksgiving is the busiest day of the year at TSA checkpoints.
- Leave home = arrival time − drive − parking or shuttle − traffic buffer.
| Situation | Arrive before departure |
|---|---|
| Domestic, carry-on only, PreCheck | About 1 h 30 min |
| Domestic, checking a bag | 2 hours |
| Domestic, holiday week | 2 h 30 min |
| International | 3 hours |
| International, holiday week | 3 h 30 min |

When to Leave for the Airport FAQs
What time should I leave for a 6 AM flight?
For a domestic 6 AM flight with a bag, aim to arrive by 4:00 AM. With a 40-minute drive plus parking and buffer, leave around 2:50–3:10 AM. Security lines at 4–6 AM are among the busiest of the day at many airports.
Is 1 hour enough time at the airport?
Rarely. Bag drop usually closes 45 minutes before a domestic flight, so an hour leaves almost no time for security. Only consider it with no bags, PreCheck, a small airport and a quiet day.
How early should I get to the airport for an international flight?
Three hours before departure. Check-in and bag drop usually close 60 minutes before international flights.
Do I need to arrive earlier at Thanksgiving?
Yes, add at least 30 minutes, especially on the Tuesday and Wednesday before and the Sunday and Monday after Thanksgiving.
