Finnair in-cabin pet policy — and the carriers that fit
Finnair allows small pets in the cabin in a carrier up to 13.8 × 11.8 × 7.9 in, stowed under the seat in front of you. Already own a carrier? Enter its measurements below to check it against this limit. The in-cabin fee is Within Europe: €60 or 7,800 Avios (7 days or more before departure) / €65 or 8,500 Avios (6 days or less). Intercontinental: €120/$130 or 15,800 Avios (7 days or more) / €130/$140 or 17,100 Avios (6 days or less). Charged per pet carrier, per journey. 0 of the 15 carriers we track clear that published limit.
That means nothing on our list fits, and nothing comes close enough to squeeze in either — at 13.8 × 11.8 × 7.9 in this is one of the tightest allowances we track. Check Finnair's own policy for cargo or an approved pet-shipper option before you book. Finnair's 7.9" height ceiling sits mid-pack among the 58 airlines we track (shared with Norwegian, Royal Air Maroc): Aegean, Air Canada, Air France and Air Transat allow more, while EL AL Israel allows only 7".

How to confirm your actual under-seat space
Finnair'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 Finnair 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 Finnair allow in the cabin?
Finnair's recommended maximum in-cabin carrier is 13.8 × 11.8 × 7.9 in. It must fit fully under the seat in front of you. Source: the Finnair pet policy.
How much does Finnair charge for an in-cabin pet?
Within Europe: €60 or 7,800 Avios (7 days or more before departure) / €65 or 8,500 Avios (6 days or less). Intercontinental: €120/$130 or 15,800 Avios (7 days or more) / €130/$140 or 17,100 Avios (6 days or less). Charged per pet carrier, per journey. Always confirm the current fee on the official Finnair pet page before you fly.
Which pet carriers fit Finnair?
No carrier we track clears Finnair's published 13.8 × 11.8 × 7.9 in outright, and none compresses down far enough either — check Finnair's cargo or approved pet-shipper options. Full shortlist: /fits/finnair/.
Is Finnair's 13.8 × 11.8 × 7.9 in limit guaranteed on every aircraft?
No. Finnair publishes four different cabin maxima in a single table rather than one number. Soft pet carriers: 55 x 40 x 23 cm on Finnair-operated flights but 55 x 40 x 20 cm on Norra-operated flights. Hard pet carriers: 35 x 30 x 20 cm on both. The smallest of these (hard carrier, 35 x 30 x 20 cm) is recorded here. Finnair also states 'the aircraft type, weather in the destination or allergic passengers on the flight may limit the number of pets', that 'pets cannot travel in Business Class on our long-haul flights, since there is not enough room under the long-haul Business Class seat', and that on Jettime-operated flights 'The carrier size requirements may vary from Finnair'. 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 Finnair?
Maximum one pet carrier per customer, with up to two pets in that carrier; Finnair usually accepts only two customers with pets in cabin per flight.
