What is the KLM Pet Policy?

Pets that can fit in a small carrier under the passenger's seat in front are welcome as carry-on passengers on KLM flights. The pet and carrier must not weigh more than 17 pounds (8 kg) altogether, and they must also be the right size for the airline. There is a limit of one pet per passenger, and the pet's owner is responsible for keeping the animal in the carrier during the journey.
