Top Airlines for Traveling With Pets From Bellevue Washington

Traveling with a pet means figuring out which airlines have the best services and straightforward rules. You want a carrier that lets your dog, cat, or other small pet fly safely and comfortably.
Things like price, pet size limits, and whether your pet can be in the cabin or has to go in cargo all make a difference.
Overview of Pet-Friendly Airlines
Several airlines from the Seattle area are actually pretty welcoming to pets. Alaska Airlines is a favorite for a lot of pet owners.
They’ll allow small animals—dogs, cats, rabbits, and birds—in the cabin for around $100 each way. Frontier does this too, but they’re a bit pickier about size.
Delta’s worth mentioning because they offer more than one way to travel with your pet. In-cabin, checked baggage, or cargo—they’ve got you covered if your pet is too big for under the seat.
Airline Policies for Pet Travel
Each airline spells out their pet rules, and you’ll want to read them. Alaska needs pets in carriers that fit under the seat. They won’t let pets in cargo on smaller planes, so check what kind of aircraft you’re flying.
Delta wants a health certificate that’s pretty recent—close to your travel date. If your pet’s flying in cargo, there are temperature rules to pay attention to.
Fees are usually based on pet size or weight—plan for around $100 per trip, sometimes more.
You’ll also need paperwork—vaccination records and travel certificates. Got a rabbit or a bird? Double check that your airline will take them.
Best Airlines for Different Types of Pets
For small pets—cats, little dogs—Alaska Airlines is a top choice. It’s easy to get them in the cabin, and the fees aren’t outrageous.
If your pet’s bigger and can’t squeeze under a seat, Delta can ship them in cargo with more safety controls. This is better for larger dogs or pets that need more space.
Frontier is budget-friendly but stricter about what pets they’ll take in the cabin. If you’re just flying to a nearby city, it could be a good deal, but the size limits are tight.
| Airline | Pet Types Accepted | In-Cabin Fee | Cargo Option | Notes |
|---|---|---|---|---|
| Alaska Airlines | Small dogs, cats, rabbits, birds | $100 | No (small planes only) | Reliable for in-cabin pets |
| Delta | Most pets including large dogs | $125+ | Yes | Multiple options, requires health certificate |
| Frontier | Small dogs and cats | Variable | No | Lower cost, strict size limits |
Booking Tips for Pet Travel
Planning ahead is honestly the best thing you can do when flying with a pet from Bellevue. You’ll need to book your pet’s spot early, follow the carrier rules, and make sure you’ve got all the paperwork.
That way, you’re less likely to run into airport surprises, and your pet will be safer.
How to Reserve a Pet Ticket
Book your pet’s spot as soon as your own flight is set. Airlines only allow a certain number of pets per flight, so don’t wait.
Alaska charges about $100 for pets in the cabin, while United is closer to $150. Usually, you’ll see a “Travel with a pet” option online, but if not, just call the airline.
Ask whether your pet can be in the cabin or has to go in cargo. Some airports have their own pet rules, so check those too.
If your pet’s small enough, most airlines let them ride in the cabin. Bigger pets might have to go as cargo or checked baggage—you’ll need to reserve that in advance, too.
Sometimes, booking early can save you up to AED 150 or more.
Pet Carrier Guidelines
Your pet needs to be in an approved carrier. For cabin travel, it has to fit under the seat.
Go for a sturdy, well-ventilated carrier that’s comfy and secure. It should be leak-proof and big enough for your pet to stand, turn around, and lie down.
Don’t forget to label the carrier with your info and your pet’s name. Keep a leash handy, just in case you have to take your pet out during security or after landing.
Carrier rules vary by airline—some want hard-sided, others are fine with soft. Double check before you show up at the airport.
Documentation and Health Certificates
Most airlines want a health certificate from your vet dated within 10 days of your flight. This shows your pet’s healthy and up on vaccinations.
Bring vaccination records—rabies, especially. Some places might need extra documents, like pet passports or microchip details.
Fill out any forms before you get to the airport. Keep both originals and copies with you.
If you’re going international, look up the destination country’s pet rules—sometimes you’ll need quarantine or more certificates.
Preparing for Your Pet’s Flight
Getting everything ready before you head to the airport is a must. Know what documents and supplies you’ll need.
This kind of prep really does make the trip smoother for both you and your pet.
Pre-Flight Checklist for Pet Owners
Get a current health certificate from your vet. Some airlines want proof of vaccinations, too.
Check the size and weight limits for pets in the cabin or cargo. It depends on the airline.
Pick a carrier that’s comfortable for your pet and meets airline rules. Label it with your contact info.
Pack food, water, and any meds your pet might need. Absorbent pads inside the carrier are a good idea.
Get your pet used to the carrier before the trip, so it’s not a total shock. Don’t feed your pet right before leaving—helps with motion sickness.
Airport Procedures at Seattle-Tacoma International
At Sea-Tac, show up early—pet check-in takes a little longer. For cabin pets, check in at the regular ticket counter.
If your pet’s checked as baggage or cargo, there are special counters for that.
Have all your documents ready—health certificate, ID, the works. At security, you’ll need to take your pet out of the carrier while it goes through the X-ray.
Try to keep your pet calm while you wait. Sea-Tac’s got pet relief areas outside the terminals—definitely use them before boarding.
Tips for a Stress-Free Boarding Experience
Bring something familiar for your pet—a blanket or toy can help them chill out. Talk to them softly before you board.
Try to avoid loud airport areas and big crowds. Keep your pet hydrated, but don’t overdo it right before the flight.
Listen for the airline’s instructions about when to put your pet in the carrier. If your pet seems really stressed, let the flight crew know.
Budget and Special Offers for Pet Flights
Flying your pet from Bellevue isn’t exactly cheap, but knowing the fees and any deals can help. Some airlines offer lower costs or discounts, so it’s worth comparing.
Comparing Airline Fees for Pet Travel
Pet fees can be all over the place. Alaska Airlines charges about $100 each way for pets, whether in-cabin or in the baggage hold. That’s pretty straightforward.
Southwest Airlines is usually the cheapest for in-cabin pets—if you’re watching your wallet, they’re a good pick.

Seasonal Discounts and Promotions
Some airlines run promotions or seasonal discounts on pet travel fees. You might spot offers that knock up to AED 150 off your pet’s flight, especially if you’re flying during off-peak times.
Honestly, it’s a good idea to check airline websites before you book. Alaska Airlines and Southwest, for example, sometimes roll out limited-time deals for pet travel.
Signing up for airline newsletters or following their social media can give you a heads-up on these offers. It’s not a guarantee, but you might just catch a break.
If you book early, some airlines lower the fees or even waive certain charges. Always ask about current promotions when you’re reserving your pet’s spot.
