  • How to prepare for check-in?

Getting ready for your flight? The check-in process is mandatory for all passengers.

Online check-in in advance

You can check in for your flight online in advance, usually between 24 and 48 hours before departure. Your airline will send you an email with instructions on how to complete the online check-in process. You will receive your boarding pass and/or a QR code with important details once you have checked in. Checking in online in advance can save you a lot of time.

If you are travelling with only hand baggage, you can proceed directly to the security screening upon arriving at the airport. However, if you have checked baggage, you will need to take it to your airline's designated check-in desk.

Check-in at the airport

If you prefer, you have the option to check in at the airport. Simply head to your airline's check-in desk where you can collect your boarding pass and drop off your checked baggage. It's important to check with your airline for specific check-in times as they may vary. Some airports also offer self-service check-in facilities, which can save you a significant amount of time.

To locate your check-in desk, refer to the information screens in the departure hall. Once you have completed the check-in process, we recommend proceeding through the security screening.

If you are travelling with Brussels Airlines or another Lufthansa Group airline (Austrian, Swiss, or Lufthansa Airlines) and have already checked in online, you can take advantage of the Self Bag Drop service at Brussels Airport.
