For domestic flights, the generally recommended time to arrive at the airport is about two hours before the scheduled departure. This allows sufficient time for check-in (at least 30-45 minutes before departure), baggage drop, security screening, and reaching the boarding gate comfortably. Some factors can influence this timing:
- If you have no checked bags and have checked in online, arriving about 1 to 1.5 hours early might be sufficient.
- Larger and busier airports or budget airlines might require extra time.
- Programs like TSA PreCheck or CLEAR can speed up security.
- Early morning or peak travel times may require extra buffer time.
For international flights, arriving about three hours early is typically advised due to longer check-in and security processes. Overall, the conventional guidance is:
- Domestic flights: 2 hours before departure.
- International flights: 3 hours before departure.
These recommendations can vary slightly depending on airline and airport, so checking with the specific airline or airport prior to travel is wise.
