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. 2 of the 15 carriers we track clear that published limit.
The Sherpa Original Deluxe (Small) leaves the most room — 0.9" on its tightest dimension, while the Mr. Peanut's Gold Series Mini (Low-Profile) only just squeaks in with nothing to spare. KLM Royal Dutch's 9.4" height ceiling sits mid-pack among the 77 airlines we track (shared with Air France, GOL Linhas Aéreas, Transavia): Aegean, Air Europa, Air Transat and Alaska allow more, while EL AL Israel allows only 7".

This table ranks by KLM Royal Dutch Airlines’s size limit — not by your pet. The weight under each carrier is what that size is rated to hold. A bag can clear the airline and still be the wrong size for the animal, which is the most common reason one goes back — measure your pet first →

How to confirm your actual under-seat space
KLM Royal Dutch Airlines's number is its published maximum, not a guarantee 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 exit rows — bulkheads have no under-seat storage and most airlines ban pets there — and check this airline's seat rules above.
- 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?
EUR 70 to EUR 500 per one-way flight, depending on route. Always confirm the current fee on the official KLM Royal Dutch Airlines pet page before you fly.
Which pet carriers fit KLM Royal Dutch Airlines?
2 of the 15 carriers we track clear 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. The heaviest pet any carrier that clears KLM Royal Dutch Airlines is rated for is 15 lb. 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
