Alaska Horizon (Horizon Air) pet policy — what it publishes, and what it does not
Alaska Horizon (Horizon Air) accepts pets in the cabin but does not publish a maximum carrier size, so we will not compute a fit rather than guess one. Alaska Horizon (Horizon Air) does not publish a cabin-pet fee on its own policy page. Confirm the under-seat allowance with Alaska Horizon (Horizon Air) before you book.
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 Alaska Horizon (Horizon Air)'s own policy for cargo or an approved pet-shipper option before you book. Alaska Horizon (Horizon Air) does not publish a maximum carrier height, so there is nothing to compare against the other airlines we track. Confirm the under-seat allowance directly with Alaska Horizon (Horizon Air).

How to confirm your actual under-seat space
Alaska Horizon (Horizon Air)'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 Alaska Horizon (Horizon Air) to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.
