Can Service Dogs Fly in the Cabin?

Service dogs receive special treatment on virtually all airlines, as they should! These hardworking pups assist people with disabilities and perform essential tasks that their handlers cannot do independently. If you're wondering which airlines allow dogs in cabin as carry-on pets that are working as a service pet, you're in luck. Here's what you need to know about flying with service animals:

• Service dogs fly free on most airlines, exempt from the pet fees other animals must pay
• No carrier required – properly trained service dogs can sit at their handler's feet or on their lap (if small enough)
• Size restrictions don't apply – airlines must accommodate service dogs regardless of breed or size
• Documentation requirements vary by airline and destination, but typically include: Verification of training/certification and veterinary health certificates

Important Note: Since 2021, most US airlines no longer recognize emotional support animals (ESAs) as service animals. Emotional support animals now generally fall under standard pet policies, including size restrictions and fees. Only dogs that have been specifically trained to perform tasks for a person with a disability qualify as service animals under Department of Transportation rules.

Documentation Timing: For international travel with service dogs, begin preparing documentation at least 30 days before your trip, as some countries have strict entry requirements and quarantine procedures.

Which US Airlines Allow Dogs in Cabin?

When it comes to flying with your furry friend as carry-on pets domestically and in North America, US carriers offer a range of pet-friendly options. Most major airlines welcome small dogs in the cabin, though policies, prices, and restrictions vary significantly.

According to our Sniffspot research with real dog owners, 82% of respondents had no airline preference when traveling with dogs, suggesting that many pet parents either don't fly frequently with their dogs or find the experience similar across carriers. However, those who do fly with their pets shared some valuable insights about their preferred airlines.

Plus the flight attendant helping us board was so nice!" This airline also appears in our list of airlines that accommodate large dogs in-cabin, making it a versatile choice for many Canadian dog owners.

Which European Airlines Allow Dogs in Cabin?

Planning a European vacation with your canine companion? European airlines tend to have some distinct differences from their North American counterparts when it comes to pet travel. 

Our Sniffspot research revealed that 88% of respondents found traveling with dogs to European destinations either "somewhat more difficult" or "much more difficult" than traveling without pets. The main challenges cited were documentation requirements and finding accommodations that accept pets once they arrived. However, many noted that European destinations tend to be more dog-friendly overall once you're there.

Airlines that Allow Large Dogs in Cabin

If your pup is on the larger side (generally over 17 lbs), your options are more limited when it comes to which airlines allow dogs in cabin. However, they're not non-existent. These airlines offer accommodations for larger dogs in the cabin:

• JSX Airlines
• La Compagnie Airlines
• Elite Airways
• WestJet Airlines

Many of these carriers require purchasing an additional seat for your pet, with prices varying based on domestic vs. international travel and your dog's weight. In other cases, your pet acts as your personal item under the seat in front of you. For the largest breeds, cargo may still be the only option on many airlines.

According to our Sniffspot survey, 41% of respondents have large dogs, making this information particularly valuable. One large dog owner shared, "Finding an airline that would accommodate my 70-pound Lab was the most challenging part of trip planning. We eventually chose JSX and it was worth every penny to have her with us rather than in cargo." 

Another respondent with a German Shepherd mentioned, "We specifically chose WestJet for our cross-country move because they were the only mainstream airline willing to work with us on accommodating our large dog in the cabin."

Alternatives to Flying Commercial Airlines

Not thrilled about navigating commercial airline pet policies or worried your furry friend is too large for the cabin but you don't want them in cargo? 

There are several alternatives that might be more comfortable for both you and your dog—though they typically come with a higher price tag.

Charter Flights

Private charter flights offer the ultimate flexibility for flying with dogs of any size:

• No size or weight restrictions for your dog
• No carrier requirements – your dog can often sit with you or move around the cabin
• No sharing space with strangers who might be allergic or uncomfortable around dogs
• Custom scheduling that works with your timing, not an airline's fixed schedule
• Direct routes to your destination, minimizing travel time and stress

Charter companies like NetJets, VistaJet, and Wheels Up welcome pets aboard with minimal restrictions. While charter flights are significantly more expensive than commercial flights (typically starting at $5,000-$15,000 depending on distance), they offer an unparalleled experience for those who can afford it.

According to our Sniffspot survey, several respondents with large or reactive dogs mentioned charter options as their preferred method when cost wasn't a concern. One dog owner shared: "After a stressful experience trying to fly my Great Dane commercially, we saved up for a charter flight for our next vacation. It was expensive but absolutely worth it—he could sit next to me, get up and stretch, and there was zero stress for either of us."

Another respondent said: "My dog doesn't do well with crowds or loud noises, so we chartered a small plane through JSX for our family reunion. The pilot even let my dog visit the cockpit before takeoff, which made for an amazing experience. A pet-friendly airline made a big difference!"

Pet-Specific Airlines

A few companies specialize exclusively in pet transport:

• Pet Airways (currently not operating but planning to resume service)
• Pet Jets (charter service specifically for pet transport)

These services are designed with animal comfort as the priority, with staff trained in pet handling and care.

Other Transport Options

As you can see, it's not always clear which airlines allow dogs in cabin, and these policies are often restrictive. If flying isn't a necessity, consider these alternatives:

• Car travel – The most flexible option, allowing complete control over your schedule and frequent breaks for your dog
• Train travel – Amtrak allows small dogs (up to 20 pounds) for trips up to seven hours for a $26 fee
• Cruise ships – Select cruise lines like Cunard's Queen Mary 2 offer kennel facilities for transatlantic crossings
• Professional pet transport services – Companies that specialize in safely moving pets domestically or internationally

Our survey revealed that 15% of respondents cited transportation as their biggest challenge when traveling with dogs. For many, driving became the preferred option. "We've changed all our vacations to road trips since getting our dog," shared one Sniffspot user. "We can control the environment, take breaks when needed, and our Border Collie actually loves car rides now. We've discovered so many amazing places we would have never seen if we were flying everywhere."

Another respondent who frequently travels with their reactive dog mentioned: "After researching all options, we bought an RV specifically for traveling with our dogs. We're like home but traveling. They have their beds, toys, and routine, plus we never have to worry about pet policies or disrupting other travelers."

When to Consider Alternatives

Alternative transportation methods may be particularly worth considering if:

• Your dog is extremely large
• Your dog experiences severe anxiety when confined
• You have a dog that falls under airline breed restrictions
• You're traveling with multiple pets
• You're concerned about cargo hold conditions
• Your dog has health issues that make traditional air travel risky
• You're relocating internationally with complex pet import requirements

"My best travel advice is to know your dog and be realistic about their needs," advised one dog owner from our survey. "We chose to drive 14 hours rather than fly 2 hours because our Aussie would have been miserable in a carrier under a seat. The drive was actually enjoyable for all of us, and it was a lot easier than arranging a domestic airline flight."

A German Shepherd owner shared: "After calculating all the added costs of flying with my dog—the fees, the special carrier, potential hotel stays due to limited flight options—I realized that driving was actually less expensive and infinitely less stressful for both of us."

Remember that while these alternatives often provide a more comfortable experience for your pet, they typically require more planning, time, and financial investment than standard commercial flights.
