For domestic flights, it is generally recommended to arrive at the airport about 1.5 to 2 hours before the scheduled departure time. This allows enough time for check-in, security screening, and reaching the gate calmly. If traveling with only carry-on luggage and having checked in online, arriving about 1 hour before is often sufficient, barring long queues or other delays. For international flights, the advised arrival time is typically 2 to 3 hours prior to departure to accommodate extra procedures such as passport control and additional security checks. The exact time may vary depending on the airport size, the airline, and the destination country. In summary:
- Domestic flights: Arrive 1.5 to 2 hours early (1 hour if no checked baggage and online check-in done).
- International flights: Arrive 2 to 3 hours early.
These recommendations also depend on the airport's size, traffic conditions, and whether you have checked in online or need to check baggage.
