KLM check-in is an easy and important step to complete before your flight. Passengers can check in online, through the KLM mobile app, at a self-service kiosk, or at the airport check-in desk. Online check-in is the fastest and most convenient method. It opens 30 hours before departure for most flights, except flights to or from the United States, where it opens 24 hours before departure. To check in online, passengers need to visit the KLM website or use the app, enter their booking code and last name, and follow the steps. During check-in, passengers can choose or change seats, add baggage, and enter passport or visa details if needed. After completing the process, they can download the boarding pass or receive it by email. It can be printed at home or saved on a mobile phone for easier boarding. Checking in online saves time at the airport and helps avoid long lines.

Passengers who do not use online check-in can check in at the airport. KLM provides self-service kiosks at many airports. These machines allow passengers to check in, choose a seat, and print their boarding pass and baggage tags. After tagging their bags, passengers can drop them at the baggage drop counter. If needed, passengers can also check in at the regular check-in desk with help from KLM staff. This is useful for those traveling with pets, infants, special luggage, or passengers needing assistance. It is recommended to arrive at the airport early to complete all check-in steps and security checks on time. For European flights, KLM advises arriving at least two hours before departure. For intercontinental flights, it is better to arrive three hours before departure. Check-in desks and baggage drop counters usually close 40 to 60 minutes before the flight, depending on the destination.

Passengers with checked baggage must make sure their luggage meets the size and weight limits based on the fare they purchased. Carry-on baggage is also limited, and passengers should check how many bags they are allowed to bring into the cabin. Most tickets include one carry-on bag and one personal item. Extra baggage can be added during online check-in or at the airport, but extra fees may apply. KLM offers SkyPriority for premium passengers and Flying Blue elite members. This service allows faster check-in, security checks, baggage handling, and boarding. Families with young children, elderly passengers, and those with reduced mobility can request special assistance during the check-in process.

For international flights, valid passports and visas are required. KLM may check travel documents at check-in or the gate, so passengers should be prepared with all necessary papers. It is important to review entry requirements for the destination country before traveling. In summary, KLM check-in can be done online, through the app, at a kiosk, or at the counter. Online check-in is the easiest and opens 30 hours before departure. Passengers should arrive at the airport on time, follow baggage rules, and have their travel documents ready for a smooth start to their journey.
