Top Airlines for Pet Travel from Westminster Colorado

Flying with your pet means you’ve got to know the rules about sizes, fees, and whether your animal goes in the cabin or cargo. Each airline does things a bit differently.
United Airlines Pet Policies
United lets you bring small cats and dogs in the cabin—as long as the carrier fits under the seat. The fee’s usually around $125 each way.
Larger pets have to go in the cargo hold, and there are some health and safety hoops to jump through. You’ll need a health certificate from your vet within 10 days of flying.
United’s PetSafe program is available for cargo pets, which is nice for peace of mind. They monitor temperature and have trained staff handling the animals.
You’ll have to check in earlier than usual if you’re bringing a pet. Some breeds aren’t allowed for safety reasons, so definitely double-check before booking.
Delta Air Lines Pet-Friendly Services
Delta’s good about letting small pets in the cabin, as long as your carrier is no bigger than 18 x 11 x 11 inches. The fee is about $125 each way.
Dogs and cats can travel as checked baggage or cargo with Delta Cargo. You’ll need a health certificate within 10 days of your flight.
Delta’s got rules about temperature, so sometimes they won’t take pets in cargo during extreme weather. They also offer a pet tracking system, which is honestly pretty cool if you’re a worrier.
Their fees are reasonable compared to some other big airlines.
Southwest Airlines Pet Program
Southwest is pretty straightforward: only small dogs and cats can fly, and only in the cabin. No cargo or checked baggage for pets.
Your pet’s carrier has to fit under the seat in front of you. The fee is $95 each way, which is one of the lower ones out there.
No extra paperwork needed besides proof of vaccination. But Southwest only takes pets on domestic flights, and it’s one pet per passenger.
If you want something affordable and simple, Southwest is easy to recommend.
Choosing the Right Flight for Your Pet
Flying your pet isn’t just about picking the cheapest ticket. You want flights that keep travel time short and let you decide if your pet’s in the cabin or cargo.
Both choices have their pros and cons.
Direct Flight Options from Denver International Airport
Direct flights out of Denver International Airport (DEN) are a game changer for pets. Less time in transit means less stress and fewer chances for something to go sideways.
Big airlines like Delta, Alaska, and Frontier all fly direct from Denver to lots of cities. Always check if pets are allowed on direct flights or if the airline is good about handling layovers.
Comparing pet fees is smart. Delta is known for moderate fees and decent pet service. Frontier can be pricier but sometimes goes to places others don’t.
If you can, book a non-stop flight. It’s just better for your pet.
Cabin vs. Cargo Pet Travel Considerations
Figure out if your pet can fly in the cabin or if they’ll have to go as cargo. Small pets under 20 pounds usually qualify for the cabin, as long as they’re in an approved carrier.
Cabin travel means you can keep an eye on your pet, but there’s limited space and usually just one pet per passenger.
Cargo is for bigger pets or if the cabin’s full. It can be safe if you’ve got a sturdy kennel, and the area is temperature-controlled, but your pet’s alone back there.
Here’s a quick look at how things stack up:
| Factor | Cabin | Cargo |
|---|---|---|
| Weight limit | Usually under 20 lbs | No strict weight limit |
| Cost | Usually lower pet fees | Higher fees and sometimes extra costs |
| Pet visibility | Pet stays with you in cabin | Pet travels with luggage |
| Safety | Constant supervision | Temperature and pressure controlled |
Pick what fits your pet’s size, health, and personality. Some airlines, like Delta, give you options for both.
Preparing Your Pet for Air Travel
You’ll want to make sure your pet is healthy and all their shots are up to date before flying. The right carrier is also key for a smooth trip.
Health and Vaccination Requirements
You’ll need a Certificate of Veterinary Inspection from a licensed vet within 10 days before you fly. This proves your pet’s good to go.
Make sure vaccinations, especially rabies, are current. Some airlines and destinations might have extra requirements.
If your pet has health issues, chat with your vet before you book. Not all pets are great candidates for flying.
Recommended Pet Carriers and Accessories
Go with a sturdy, airline-approved carrier. Your pet should be able to stand up, turn around, and lie down without being squished.
Label the carrier clearly with your info and your pet’s name. Toss a leash or harness inside if you can.
A favorite blanket or toy can help keep your pet calm. Don’t feed them right before the flight—nobody wants a nauseous pup or kitty on board.
Always double-check the airline’s carrier size rules. They can be weirdly specific.
