Alaska Airlines in-cabin pet policy — and the carriers that fit
Alaska Airlines allows small pets in the cabin in a carrier up to 17 × 11 × 9.5 in, stowed under the seat in front of you. The in-cabin fee is $100 each way. 1 of the 15 carriers we track clears that published limit.
The Sherpa Original Deluxe (Small) is the one that clears it, with 1" to spare on its tightest dimension. Alaska's 9.5" height ceiling sits mid-pack among the 17 airlines we track (shared with Hawaiian): Delta, American, United and Frontier allow more, while Air Canada allows only 8".

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