Check-in at an airport is the process through which a passenger confirms their travel with the airline and completes the required formalities before the flight.
Is Check-in Important for Travellers?
Yes. Check-in is important because:
- You generally need to complete check-in before travelling on a flight.
- After completing check-in, you receive or can access your boarding pass, which is required for boarding the aircraft.
- Depending on the airline, you may be able to select or change your seat.
- You may be able to request additional baggage or manage other travel preferences.
- You can usually check in online (web check-in) or at the airport.
How Can You Check In?
Online check-in:
- You can check in through the airline’s website or app, where available.
- The airline may ask for your PNR and last name or email address to retrieve your booking.

Airport check-in:
- You can use a self-service kiosk, where available.
- You can also visit the airline’s check-in counter.
- After completing check-in at the airport, you may receive a printed boarding pass.
If you have already completed web check-in, you may still be able to make certain changes or complete additional formalities at the airport, depending on the airline and booking.
Check-in Closing Time
Airlines generally have a fixed check-in closing time. If you do not complete check-in within the permitted period, you may not be accepted for that flight.
Check-in is different from security screening. Check-in is handled by the airline, while security screening is a separate airport security process.
