But don’t worry – we’re here to help!

Pet-Friendly Airline Info: The Basics We’ve Covered

flying with your dog

Every airline has its own set of rules for canine travel, but we’ve tackled the basics to give a snapshot of each. Hopefully, this makes narrowing your options a tad easier.

Some of the things we cover below include:

  • Flying with your dog in the cabin. Not every airline allows dogs to travel with passengers in the plane’s cabin. Some limit canines to the cargo area only, while others allow for cabin travel if canines meet specific size, behavior, or containment requirements. Typically, well-behaved, small dogs that can be stowed in an airline-approved pet carrier under an airline seat are allowed, though there are also a very few airlines that allow large breeds to travel via cabin too.
  • Flying with your dog in the cargo hold. Some airlines allow dogs to travel in the cargo hold. Housed in a carrier that meets strict safety standards, cargo-held canines generally have less strict size requirements than cabin-dwelling doggos, allowing larger breeds to fly. However, current travel trends have made cargo travel hard to come by for dogs.
  • Banned breeds. Many airlines ban certain breeds from flying in the cabin or cargo area. This typically includes brachycephalic (short-headed) dogs, though some providers may prohibit other breeds from flying.
  • Rules for emotional support animals and service dogs. Previously many airlines allow ESAs to travel differently than everyday pet dogs, but the vast majority of airlines have done away with ESAs on flights. However, per federal law, service dogs are granted access to planes with their handler, regardless of the airlines’ pet policy. Not sure about the difference between service dogs vs ESA dogs – let us explain!
  • Pet flying fees. The cost of traveling with your dog varies significantly from airline to airline, with some pet passes costing little more than a checked-bag fee while others can be a few hundred dollars or more. These fees may change according to your dog’s size and travel method too.
  • Weight restrictions for flying dogs. Weight restrictions can be a real bite, particularly if you plan to have your pooch travel in the cabin. Cabin weight limits tend to be much lower than cargo limits, but it’s important in both scenarios to weigh your pup and factor in the weight of his travel crate. This eliminates potential airport surprises, as your pooch is weighed in his carrier before boarding. Generally speaking, flying in the cabin won’t be a viable option unless your dog is under 20 lbs.
  • Dog crate size for riding in the cabin. Most airlines require kenneled canines to be stowed under an airline if traveling in the cabin, meaning your dog’s crate needs to meet specific size criteria. These sizing guidelines vary from airline to airline, so always double-check the rules, especially if you have connecting flights with different airlines. In addition, your dog should be able to stand, sit, and turn around in his carrier.
  • Dog crate size for flying in the cargo hold. Cargo crates must meet International Air Transport Association (IATA) requirements, which include strict size, locking, and ventilation standards. As with cabin carriers, your dog must be able to stand, sit, and turn around comfortably in the kennel.
  • Maximum number of pets per person. Most airlines allow one pet per passenger, but some allow two. Sometimes, this means two pets in the same carrier or two pets housed in separate carriers. But just because you can fit two dogs in a carrier, that doesn’t mean you should. Not every dog likes being crammed with a friend while already enduring the stress of travel.
  • Maximum number of pets per airplane. Airlines typically limit the number of animals on a flight, which can lead to travel nightmares if you don’t book early. A six-pet limit is most commonly seen, but some have limits as low as two. Yikes!
  • Dog age requirements for flying. Like destinations, each airline sets its own rules regarding how old a dog must be to travel. Most of the time, this pertains to puppies, but senior dogs may also face scrutiny, particularly those in poor health.
  • Special notes and miscellaneous four-footed flying facts. We’ll note if an airline has any special rules or pet perks. This might include things like special document requirements, restrictions, and more.
Pet Care Pro-Tip:

While we’re covering the basics in this article, you should still discuss your travel plans with an airline representative to ensure you and your pooch fly without issue. Rules are ever-changing, so it’s best to err on the side of caution.

2. JSX

Best Low-Stress Pet-Friendly Airline

Big or small, your canine cany enjoy worry-free traveling with this carrier.

Get More Information

About: JSX provides the comfort of private flights at an affordable rate to travelers across a limited portion of the United States. With its relatively relaxed pet policy, it’s a top-notch pick for low-stress flying with your dog.

@rigatoni_reacts It was kinda private. 😅 #jsx #privateflight ♬ swing lynn – lovdfilmz

Keep in mind that JSX functions as a public charter operator — it basically shared private air travel. On top of being able to bring your larger-sized pet into the cabin with you, that also means you get a host of other perks that come with private flights, such as:

  • Private terminals and separate security
  • Business class legroom with roomy seats
  • Intimate 30-seat jets
  • Plane-side baggage retrieval immediately after unloading passengers

Sounds amazing, right?

The downside is that tickets are pricier than your normal flight — expect to pay 2-3x what you’d pay with a standard airline. Plus, JSX has a very limited number of flight paths, primarily in the southwest region of the United States.

Still, if you’re going where JSX flies, it can’t get much better for you and your pooch.

General Tips for Flying with Your Pet

pet flying tips and tricks

Flying to a destination with your furry adventure buddy is loads of fun, but to keep it that way, you should follow a few rules of the skies, including: 

  • Book early. Most airlines limit the amount of pets allowed per flight. To snag one of these coveted spots for your sniffer, book your trip as soon as possible.
  • Double-check all of the details with the airline. When in doubt, ask. Airline rules are ever-changing, especially with continued complications in a post-pandemic world. It’s better to dot all of your Is and cross your Ts than to be surprised at check-in.
  • Select an airline-approved crate when flying cargo. Carriers come in all shapes and sizes, many of which aren’t airline compliant with their gadgets and gizmos. Check size requirements with your airline and other concerns, such as acceptable materials or rules about crate locks. Also, note that these can vary by dog breed.
  • Talk to your vet. Square away vaccination updates and health checks before planning any trips with your pup. It’s important to determine if your dog is fit to fly and to have your ducks in a row paperwork-wise for vaccinations.
  • Pack medications. Sometimes travel brain gets the best of us and we forget the most important everyday items like underwear or your dog’s medications. If possible, these should be among the first supplies you pack. They should be in their original containers with your vet’s information too to avoid any transparency problems.
  • Consider your pet’s needs over yours. Not every dog likes to fly or is well-suited for flight. Health issues and personality quirks can put unnecessary stress on your canine. While you may be looking forward to taking in the sights and sounds of an exotic locale, your dog may be too anxious to enjoy such a trip. Sometimes staying home with a trusted petsitter is best.
  • Can’t fly? Consider ground transportation. If your dog isn’t a good fit for flying, there are plenty of great pet ground transportation services that can drive your dog to your final destination. With shared van and private van options, you can usually find a service that won’t break your budget (although overall, pet ground transport is definitely pricier than flying, as it takes longer and requires more manual labor on the driver’s part).

Pet-Friendly Airlines: FAQ

dog flying questions

Flying with your dog can be a head scratcher sometimes. Check out these commonly asked questions to brush up on your knowledge about traveling by air with your dog.

Is it safe to travel with your pet?

In many cases, yes.

Most healthy dogs fly in an airplane’s cabin without issue, especially the most travel-friendly breeds.

Risks increase if your dog is brachycephalic (short-faced,) medically frail, or traveling in the cargo area. Most airlines do not even allow any kind of plane travel for brachycephalic breeds or breeds that are prone to issues like overheating.

Traveling by air with young puppies or seniors is also not advised and often not allowed by major airlines.

If you have any concerns about your dog’s safety during travel, contact your vet to discuss if flying is the best option or if a staycation is a better pupper plan.

What is the safest airline for pets?

According to a 2018 report by the Department of Transportation detailing incidents involving the loss, injury, or death of animals during air transportation, airlines reporting zero incidents include Horizon Air, Republic Airways, Endeavor Air, Mesa Airlines, ExpressJet Airlines, GoJet Airlines, Compass Airline, CommutAir, Envoy Air, and Sun Country Airlines.

However, it’s worth noting that these airlines transported far fewer animals than major carriers, with the majority flying less than 10,000 animals annually.

Alaska Airlines reported the least incidents among major airlines, with 1 injury per 143,634 pets flown. SkyWest Airlines and American Airlines also experienced fewer incidents. The worst-performing major airline was Hawaiian Airlines, with 3 deaths in the 9,505 pets flown.

Despite the media hyper-focusing on pet deaths while flying, these occasions are very rare. Pet travel by plan is generally quite safe.

What documents do I need for my pet to fly?

The documents needed vary by airline and destination. Some ask for nothing, while most require a health certificate.

Completed by a vet, this certificate states that your dog is healthy enough to fly and free of infectious diseases. Shot records may also be required, depending on the airline and destination. International flights generally have the strictest document requirements.

What are some of the new airline pet restrictions after the pandemic?

The pandemic greatly affected pet travel with employee shortages and an uptick in flight cancellations. In response, airlines have limited cargo shipment of animals, some have banned emotional support animals, and others increased fees for pets traveling in the cabin.

The CDC has also tightened the rules surrounding dogs coming to the United States, with new age, vaccination, microchipping, and location restrictions. This is in response to several rabies-infected dogs arriving in the U.S. during the pandemic.

Which airlines allow dogs on the plane?

Several airlines allow dogs to fly, including American Airlines, Delta, United Airlines, and JetBlue. However, airline canine travel rules vary, so always call ahead to ensure your pooch can take to the skies.

Does federal law allow dogs on airplanes?

Federal law leaves it up to airlines if pets are permitted to travel via cabin with passengers or as cargo. These restrictions do not apply to service animals. Federal law states that service animals are allowed in the cabin of any airplane and aren’t subject to carrier or health certificate requirements. There’s also no limit on the number of service animals on a flight.

Can my dog sit on my lap during a flight?

Probably not. Most airlines require dogs to stay kenneled in an airline-approved pet carrier and under the seat in front of you for the flight duration. This keeps you, your pet, and other passengers safe in case of turbulence and other airtime events.

Can pets fly alone?

Maybe. Some airlines allow pets to fly alone while others do not. There are many pet transport services that can aid in canine travel if you can’t travel with them.

What is the best airline for traveling with a pet?

Our top pick for the best airline to travel with a pet is JSX. Since the flights are semi-private and you can take any sized dog onto the plane without a crate, it’s the ideal flying experience for you and your pooch. The only downside is that there aren’t many flight destinations, and the tickets can be pricey.
