Ryanair pet policy — why pets cannot travel in the cabin

Ryanair does not accept pets in the cabin, so no carrier size will make it work — this is a policy limit, not a size limit. Ryanair does not publish a cabin-pet fee on its own policy page. Your options are Ryanair's cargo service or an approved pet shipper. If you need your pet with you in the cabin, you need a different airline.

Ryanair does not accept pets in the cabin

That means nothing on our list fits, and nothing comes close enough to squeeze in either — at not published this is one of the tightest allowances we track. Check Ryanair's own policy for cargo or an approved pet-shipper option before you book. Ryanair does not accept pets in the cabin, so there is no carrier height to compare. Its own policy covers cargo or approved pet-shipper options instead.

Carrier sizes we track

How to confirm your actual under-seat space

Ryanair's number is a fleet-wide recommendation, not a promise for your exact seat. Before you buy or fly:

1. Check which aircraft operates your flight (in your booking or on a seat-map site).
2. Avoid bulkhead and some window seats — they have less (or no) under-seat storage.
3. Call Ryanair to confirm under-seat dimensions for that aircraft, or
4. Choose a collapsible / flexible-height carrier that adapts to a tighter space.
