Alaska Airlines's cited pet policy lists a soft-sided in-cabin carrier limit of 17 × 11 × 9.5 in (hard-sided: 17 × 11 × 7.5 in) as of 2026-07-10. Cabin Pet Fit compares carrier dimensions against that published limit; gate acceptance is not guaranteed.
The cited record lists $100 each way ($35 within Hawaii). Fees change; always confirm on the airline's official pet page before you book.
No. A match means the carrier’s listed external dimensions compare inside the published limit. Gate agents, aircraft under-seat space, a rigid frame, and how full the carrier is can still affect real-world fit. We also do not advise on your pet’s health or fitness to fly.
