Flying Route

Passengers can check-in online anywhere in the world 30 hours before the scheduled departure. Each boarding pass consists of a bar code and can be printed from home or office. KLM also provides additional services such as telephone check-in and check-in from a mobile phone.

Anyone carrying a paper boarding pass can deposit their luggage at any counter and proceed directly to the security counter.


Depending on the travel route, the baggage allowance for passengers is based on either the weight or piece concept. Each passenger can carry a weight up to 20kg/44 lbs in economy and 30kg/66 lbs in superior class. The routes that adhere to the piece concept allow passengers to check-in two items of baggage where each bag should not exceed 23 kg/50 lbs per bag in economy and 32 kg/70 lbs in World business class or Europe Select.

The bag dimensions vary according to the chosen class of the traveler. Flying Blue members get extra amenities when booking baggage.

Traveling Infants

KLM was the first to introduce packages for children that included special meals, toys and various other items of interest. Parents are allowed to carry infants on their laps. An infant is described as anyone who is less than two years old at the time of departure. General items of necessity like strollers and diaper bags are allowed on-flight, but travelers should consult a KLM agent to verify complete details before boarding. Cribs are also available on all intercontinental flights.


KLM keeps young children and babies entertained by providing a special menu free of cost. Anyone less than 12 years old is considered a minor and is required to be accompanied by an adult (18-years-old or older). Children from five to eleven can use the KLM's unaccompanied minor service program. Even teenagers up to seventeen years old are encouraged to use this program. KLM has fixed fares for adults, minors and infants. The fare for minors varies according to the route, but generally is 80% of the full ticket price of an adult traveler. There is no charge for lap infant, but booking a full seat may cost a little extra.


Small cats and dogs weighing no more than 6 kg/13 lbs are permitted inside the cabins. They must be secured inside a kennel bag or a container. For larger animals, special ventilated parts of the cargo hold provide a safe journey. These larger pets should not exceed 75 kg/165 lbs. If a visitor still wants to carry an animal that is more than 75 kg.165 lbs, the KLM-Air France cargo can take care of these special needs. The charges on this cargo vary based on the length of the flight and may cost 40, 80 or 160 Euro per segment. Guide and service dogs are exempt form these rules.
