KLM Airlines Pet Policy

The KLM Royal Dutch Airlines pet policy is as follows:
Small cats and dogs are accepted in the Economy Class cabin of most KLM flights, and in Business Class on most KLM flights within Europe.
Total weight of your pet and travel bag or kennel combined may be max. 8 kg (18 lbs).
It’s not possible to bring a pet in the cabin in Business Class on intercontinental KLM flights, because there is no space for your pet under the seat in front of you.
Your cat or dog may travel in a ventilated part of the hold on most KLM flights.
Your pet cannot travel in the hold of our Boeing 787-9 and Boeing 787-10 aircraft. During winter, your pet may not travel in the hold on KLM Cityhopper flights (Embraer 175 and Embraer 190) of 2 hours or more.
Snub-nosed animals such as boxers, Pekinese and Persian cats can have trouble breathing during the flight, due to high temperatures and stress. To ensure their well-being, most snub-nosed animals may not be transported in the hold. However, they may be transported in the cabin or as cargo. English and French bulldogs, Boston terriers and pugs may only be transported in the cabin.
If you want to take more than 3 pets with you, they must be shipped as cargo.
Your pet should also be transported as cargo by Air France-KLM Cargo if: your pet and kennel combined weigh more than 75 kg (165 lbs); the kennel is larger than 292 cm/115 inch (l + w + h); your pet is not travelling on the same flight as you are; or your pet is travelling to a country whose authorities allow the transportation of pets as cargo only.
To transport your pet as cargo, you should contact a specialised cargo agent. You can find a list of cargo agents in the Netherlands at the Air France-KLM Cargo website.
Taking a pet to a foreign country involves preparation and planning far in advance of your departure date. Requirements for pet travel to a foreign country are set by the destination country. If you are you traveling to another country and bringing along your pet you’ll need to meet the animal health requirements of the country you are visiting.
