Hey, I'm Marco — and I Almost Got Denied Boarding With Mochi
I learned the hard way that Alaska Airlines has some specific rules about flying with pets, and they don't mess around. When I tried to book a cabin seat for my 11kg French Bulldog, Mochi, I hit a wall immediately. Here's what nobody tells you upfront: Alaska Airlines doesn't allow brachycephalic (snub-nosed) breeds in the cabin. That includes Bulldogs, Pugs, and Persian cats. I had to scramble to figure out my options, and I'm sharing everything I learned so you don't end up in the same panic I did.
This guide covers everything you need to know about flying with pets on Alaska Airlines — whether you've got a regular dog, a cat, or you're dealing with breed restrictions like I am.
Can My Pet Fly in the Cabin?
Yes, but with major caveats. Alaska Airlines allows dogs and cats in the cabin on domestic flights only. Here's the catch: your pet must be at least 16 weeks old, weigh no more than 9kg (about 20 lbs) including the carrier, and fit in a soft-sided carrier that slides under the seat in front of you.
The carrier dimensions are strict: 43cm long × 28cm wide × 24cm tall (roughly 17" × 11" × 9.5"). I measured Mochi's old carrier three times before accepting she wouldn't fit the policy anyway.
Here's the brachycephalic bomb: Alaska Airlines bans Bulldogs, Pugs, and Persian cats from cabin travel. If your breed has a flat face and breathing challenges, the cabin is off-limits. Period. No exceptions I could find. This is an industry-wide safety standard, but it hit me hard.
What About Brachycephalic Breeds Like My Frenchie?
I wish someone had told me this upfront: if you have a brachycephalic breed, you cannot fly in the cabin with Alaska Airlines. The airline restricts these breeds due to respiratory risks during flight — the cabin pressure and temperature changes are genuinely risky for snub-nosed dogs and cats.
Your options are:
- Cargo transport — also banned for brachycephalic breeds (industry standard)
- Checked baggage — also banned for brachycephalic breeds
- Pet Connect™ Cargo Service — Alaska Air Cargo offers specialized live animal transport, but you'll need to confirm if brachycephalic breeds are accepted under their program
- Leave your pet with a trusted sitter or boarding facility — honestly, this might be your safest bet
- Drive or take a pet-friendly ground transport service — slower, but your pet stays safe
I ended up boarding Mochi with a trusted friend for my last trip. It wasn't ideal, but it was safer than forcing her onto a plane.

How Do I Book a Pet on Alaska Airlines?
You cannot book online. This is one of those annoying quirks that caught me off guard. You must call Alaska Airlines reservations at (800) 252-7522 or use their online chat to add your pet to your booking. There's no self-service option.
Here's what to have ready when you call:
- Your flight confirmation number
- Your pet's name, breed, and weight
- Confirmation that your pet is at least 16 weeks old
- Your carrier dimensions (to verify it fits the requirements)
Book as early as possible. While there's no specific advance window, Alaska Airlines limits the number of pets per flight. I've heard of flights filling up, so don't wait until the last minute.
What Carrier Do I Need?
Alaska Airlines requires a soft-sided carrier for cabin travel. Hard-sided crates won't fit under the seat. The carrier must have:
- Mesh ventilation on the sides (your pet needs to breathe)
- An absorbent liner or mat inside (accidents happen, and you don't want a mess on the plane)
- Dimensions that fit the 43cm × 28cm × 24cm limit
I use an Amazon Basics soft-sided carrier for reference — it's affordable and meets the specs. Make sure you test it at home first. Your pet should be able to stand, turn around, and lie down comfortably.
What About International Travel?
If you're flying internationally with your pet, you'll need a health certificate issued by a vet within 10 days of your departure date. This applies to cabin, cargo, and checked baggage travel. The certificate confirms your pet is healthy and up-to-date on vaccinations.
Here's the thing: different countries have different import requirements. If you're traveling to the United Kingdom, Australia, or other countries with strict quarantine laws, you'll need additional permits and documentation. Check your destination's specific requirements early — some countries require permits issued weeks in advance.
For domestic flights, a health certificate is not required by Alaska Airlines, but I always get one anyway. It's cheap insurance.
What About Service Animals and ESAs?
Trained service dogs travel for free and are exempt from the weight limit, carrier requirement, and breed restrictions. They travel at your feet in the cabin.
Emotional support animals (ESAs) are not recognized by Alaska Airlines. If you have an ESA letter, it won't help you. Your pet travels under the standard pet policy with all applicable fees and restrictions. This is a DOT regulation, not an Alaska Airlines quirk, but it's important to know.
If you have a trained service dog, you'll need to notify Alaska Airlines when you book, but there's no fee.
Temperature Restrictions — A Real Gotcha
Here's something I didn't expect: Alaska Airlines won't transport pets in cargo or checked baggage if the temperature at the origin or destination exceeds 29.4°C (85°F) or drops below -6.7°C (20°F). This is an industry standard, but it's crucial if you're traveling during summer or winter.
If you're flying to Phoenix in July or Minneapolis in January, your pet might not be allowed to travel. Some airlines allow travel in colder conditions if you get a vet's acclimation certificate, but we're still verifying this with Alaska Airlines directly.
Check the weather forecast for your destination before booking. If temperatures are borderline, call Alaska Airlines to confirm.
Can I Sedate My Pet for the Flight?
No. Do not sedate your pet. IATA (International Air Transport Association) regulations prohibit sedation during air travel. A sedated animal cannot maintain balance or respond to emergencies. This applies to all commercial airlines worldwide.
I know flying is stressful for pets, but sedation is not the answer. Instead, acclimate your pet to the carrier at home, keep them calm with familiar toys, and talk to your vet about natural calming supplements if needed.
What About Cargo and Checked Baggage?
Alaska Airlines allows pets in cargo and checked baggage, but brachycephalic breeds are banned (so Mochi is out). If your pet qualifies, here's what you need to know:
- Hard-sided IATA-compliant crate required (not soft-sided)
- Attached water bowl that can be filled from outside the crate
- Absorbent liner inside the crate
- "Live Animals" labels with orientation arrows on the crate
- Health certificate required (issued within 10 days of departure)
- Minimum age: 10 weeks (younger than cabin travel)
- Temperature restrictions apply (29.4°C / 85°F max, -6.7°C / 20°F min)
- Advance booking required — call Alaska Airlines cargo
Cargo travel is more stressful for pets than cabin travel. Your pet will be in the hold with luggage, and you won't be able to check on them. I'd only choose this option if cabin travel isn't possible and I had no other choice.
Military Pet Program
If you're active-duty military on PCS (Permanent Change of Station) orders, Alaska Airlines offers fee waivers or reduced rates for pet travel. Contact Alaska Airlines directly to confirm your eligibility and get details on the military pet program.
What You Need to Do
- Check if your breed is brachycephalic. If yes, cabin travel is not an option. Explore alternatives.
- Verify your pet's age. Must be at least 16 weeks for cabin travel.
- Measure and weigh your pet with the carrier. Must be 9kg or less combined.
- Get a soft-sided carrier that fits 43cm × 28cm × 24cm.
- Add an absorbent liner to the carrier.
- Call Alaska Airlines at (800) 252-7522 to book your pet. Do this early.
- For international travel, schedule a vet appointment for a health certificate (issued within 10 days of departure).
- Check destination temperature forecasts. If extreme, confirm with Alaska Airlines that travel is allowed.
- Acclimate your pet to the carrier at home before the flight.
- Arrive early on flight day to allow extra time for pet check-in.
Real Talk: Is Flying With Your Pet Worth It?
Honestly? After my experience with Mochi, I think twice before flying with her. The restrictions, the fees, the stress on the animal — it adds up. If your trip is short or you have a trusted pet sitter, consider leaving your pet at home. If you must fly, cabin travel is less stressful than cargo, but it's still not ideal for anxious pets.

Final Thoughts
Alaska Airlines is clear about its pet policies, even if they're restrictive. The brachycephalic ban stung, but I understand the safety reasoning. If you've got a regular dog or cat that meets the weight and age requirements, cabin travel is doable — just book by phone and plan ahead.
