KLM Royal Dutch Airlines in-cabin pet policy — and the carriers that fit
KLM Royal Dutch Airlines allows small pets in the cabin in a carrier up to 18.1 × 11 × 9.4 in, stowed under the seat in front of you. Already own a carrier? Enter its measurements below to check it against this limit. In-cabin fee: EUR 70 to EUR 500 per one-way flight, depending on route. 1 of the 15 carriers we track clears that published limit.
The Sherpa Original Deluxe (Small) is the one that clears it, with 0.9" to spare on its tightest dimension. KLM Royal Dutch's 9.4" height ceiling sits mid-pack among the 58 airlines we track (shared with Air France): Aegean, Air Transat, Alaska and Allegiant allow more, while EL AL Israel allows only 7".

How to confirm your actual under-seat space
KLM Royal Dutch Airlines's number is a fleet-wide recommendation, not a promise for your exact seat. Before you buy or fly:
- Check which aircraft operates your flight (in your booking or on a seat-map site).
- Avoid bulkhead and some window seats — they have less (or no) under-seat storage.
- Call KLM Royal Dutch Airlines to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.

Common questions
What size pet carrier does KLM Royal Dutch Airlines allow in the cabin?
KLM Royal Dutch Airlines's recommended maximum in-cabin carrier is 18.1 × 11 × 9.4 in. It must fit fully under the seat in front of you. Source: the KLM Royal Dutch Airlines pet policy.
How much does KLM Royal Dutch Airlines charge for an in-cabin pet?

Which pet carriers fit KLM Royal Dutch Airlines?
1 of the 15 carriers we track clears KLM Royal Dutch Airlines's published 18.1 × 11 × 9.4 in. The roomiest is the Sherpa Original Deluxe (Small), with 0.9" to spare on its tightest dimension. Full shortlist: /fits/klm/.
Is KLM Royal Dutch Airlines's 18.1 × 11 × 9.4 in limit guaranteed on every aircraft?
No. KLM states "There's limited space for pets in our aircraft; the number of pets we can bring depends on the type of aircraft, destination, and operating airline", and that in Premium Comfort and intercontinental Business "it's not possible to put a kennel underneath the seat in front of you" — so cabin carriage is not guaranteed on a given flight even within the published size. Treat the published figure as a fleet-wide maximum, not a promise for your seat, and prefer a collapsible or flexible-height carrier.
How many pets can I bring in the cabin on KLM Royal Dutch Airlines?
1 cat or dog in the cabin, per passenger — Economy Class only, or Business Class within Europe (no cabin pets in Premium Comfort or Business on intercontinental routes). Species accepted: cats, dogs. Weight limit: 8 kg (17.6 lb) including the travel bag or kennel. Reserve via My Trip as soon as possible after booking your flight, and no later than 48 hours before departure
