Finding airlines that allow dogs in cabin can be surprisingly confusing. Every airline seems to have different rules for pet fees, carrier sizes, weight limits, route restrictions, and carrier requirements.
One of the most searched airlines is American, so I broke down the American Airlines pet policy in its own guide.

After flying all over the world with my dog Puglo, I’ve learned that there are more options out there than most people realize, but some regions are definitely easier than others. We’ve had smooth experiences on major U.S. airlines like Delta and United, Latin America has been one of my favorite regions to fly from because many airlines still accept emotional support animals, and Europe has been much more limiting because of the strict 8 kg weight limit on many airlines.
United is one of the flexible ones for in-cabin pets. I cover the fees, carrier rules, and booking steps in my full guide to flying with your dog on United.
That said, flying with a dog is absolutely possible with the right planning. In this guide, I’m breaking down the main airlines that allow dogs in cabin by region, including airlines that still accept emotional support animals, which regions are easiest to travel in, and what to know before you book.
Find the right airline faster – I put together a guide with 70+ airlines that allow dogs in cabin, including key details like weight limits, carrier rules, airlines that alloweand international options. It’s designed to save you hours of research and help you quickly narrow down the best fit for your dog.
Do airlines allow dogs in cabin?
Yes, many airlines do allow dogs in cabin, but usually only if they are small enough to fit comfortably in an airline approved carrier under the seat in front of you.
That said, the rules vary a lot. Some airlines have strict weight limits, while others focus more on whether the carrier fits under the seat. Policies can also differ depending on the route, aircraft, and destination country, so an airline that allows dogs on domestic flights may not allow them on international ones.
Most airlines only allow a limited number of pets in cabin per flight, which means it’s important to book early and reserve your dog’s spot as soon as possible. Some also have breed restrictions, and snub nosed dogs like pugs may face extra rules depending on the airline.
If you’re traveling with a larger dog, the options are much more limited, but there are a few airlines that may allow larger dogs in cabin in certain situations, which I’ll cover later in this guide. Emotional support animal policies have also changed a lot in recent years, though a small number of airlines still accept them on select routes.
U.S. airlines that allow dogs in cabin
When it comes to airlines that allow dogs in cabin, the U.S. is one of the most pet-friendly regions, which is great news whether you live there or are traveling through. Most major U.S. airlines do not have a set pet weight limit for in-cabin travel. Instead, the main requirement is that your dog fits comfortably in an approved carrier under the seat in front of you.
Personally, I’ve had good experiences flying with Puglo on major U.S. airlines like Delta and United, and we’ve never had issues. In my experience, U.S. carriers tend to be some of the easiest to fly with as long as your dog is comfortable in the carrier and you’ve prepared everything properly ahead of time.
Your dog should be able to stand up, turn around, and lie down comfortably inside the carrier. Enforcement can still come down to the discretion of the check-in agent, so even if your dog technically meets the requirements, how comfortable they appear in the carrier can matter.
Here are some of the major U.S. airlines that allow dogs in cabin:
- Delta Air Lines
- United Airlines
- American Airlines
- JetBlue
- Alaska Airlines
- Southwest Airlines
- Hawaiian Airlines
- Frontier Airlines
I’d recommend always double checking the airline’s pet policy before booking, since fees, route restrictions, carrier dimensions, and the number of pets allowed per flight can vary.
Canadian airlines that allow dogs in cabin
Canadian airlines are also quite pet-friendly, with most major carriers allowing small dogs in cabin as long as they meet the airline’s carrier requirements. Major airlines like Air Canada and WestJet do not have specified pet weight limits for in-cabin travel, while some smaller airlines, such as Flair, do. Notably, Air Transat is also one of the few airlines that still accepts emotional support animals on some routes, which can make it a useful option for some travelers.
Overall, we’ve had good experiences flying in Canada with Puglo. The one exception was being denied once by Air Canada because they said he was too tall for his carrier, although that actually happened at the Mexico City airport on our way to Canada. That experience was a good reminder that enforcement can still come down to the judgment of the staff at check in.
If you want a more detailed breakdown, including pet fees, carrier rules, and airline-specific notes, you can read my full guide to Canadian airlines that allow dogs in cabin.
Here are some of the main Canadian airlines that allow dogs in cabin:
- Air Canada
- WestJet
- Air Transat
- Porter Airlines
- Flair Airlines
- PAL Airlines
- Pacific Coastal Airlines
- Canadian North
As always, it’s a good idea to double check the airline’s pet policy before booking, since rules around carrier dimensions, fees, route restrictions, and emotional support animals can change.
Latin American airlines that allow dogs in cabin
Latin America is one of the most dog-friendly regions I’ve come across when it comes to flying with pets, and it’s one of my favorite parts about living in Mexico with a dog. Many airlines in this region allow dogs in cabin, often with more generous policies than you’ll find in places like Europe or North America.
Personally, this is the region where I’ve had some of the easiest experiences flying with Puglo. We often fly from Mexico as an emotional support animal, and having access to airlines in this region that still accept ESAs has made a huge difference in how we travel. It opens up a lot more options and makes flying with a dog feel so much less restrictive.
Here are some of the major Latin American airlines that allow dogs in cabin:
As always, make sure to check the latest pet policy before booking since rules around carrier size, documentation, pet fees, and emotional support animals can change.
Caribbean airlines that allow dogs in cabin
There are a few Caribbean airlines that accept pets in cabin, though the rules do tend to be stricter than in regions like the U.S. or Latin America. Weight limits are often lower, and some airlines have more limited routes or fewer pet spots available per flight.
I haven’t traveled around this region with Puglo yet, so I can’t speak from personal experience here, but there are still a few airlines worth checking if you’re planning to island hop with your dog.
Here are a few Caribbean airlines that allow pets in cabin:
European airlines that allow dogs in cabin
Europe tends to have some of the strictest rules when it comes to flying with pets in cabin. Most European airlines have an 8 kg weight limit, including the carrier, which can make it much harder for slightly larger small dogs to qualify. There are a few airlines that allow up to 10 kg, and Italy is notably leading the way with a new policy expected to allow dogs up to 30 kg in cabin starting in summer 2026, which could be a huge step forward for dog owners traveling in Europe.
Because of those stricter weight limits, Europe is one of the regions where flying with Puglo has been more limiting for us. When we’re traveling in Europe, we often take alternative transport like trains instead, which is one of the reasons I love traveling there. Train travel in Europe is generally much easier with a dog and gives us far more flexibility than trying to work around airline restrictions.
If you want a more detailed breakdown, you can read my full guide to European airlines that allow dogs in cabin, where I share more on weight limits, airline rules, and which options may work best for different sized dogs. I also cover this in more detail in my airline guide.
Here are some European airlines that allow dogs in cabin:
- KLM
- Lufthansa
- Air France
- SWISS
- Iberia
- TAP Air Portugal
- Eurowings
- Corendon Airlines
- Vueling
- ITA Airways
- Volotea
- Plus Ultra
- Cyprus Airways
- KM Malta Airlines
Middle Eastern airlines that allow dogs in cabin
The Middle East can be a more challenging region when it comes to flying with dogs in cabin, since many airlines in this part of the world only allow service dogs and do not accept pets in cabin at all. That said, there are still a few airlines that do allow dogs in cabin, so it’s not impossible. You may just have fewer options to work with.
I haven’t traveled around this region with Puglo yet, so I can’t share personal experience here, but based on my research, this is one of the regions where it’s especially important to check the airline’s policy carefully before booking. In some cases, the rules may also vary depending on the route.
Here are a few Middle Eastern airlines that allow dogs in cabin:
Asian airlines that allow dogs in cabin
Asia is one of the trickiest regions to travel with a dog. Many airlines do not allow pets in cabin at all, and the ones that do often have very low weight limits, usually around 6 or 7 kg including the carrier. That can make it especially difficult if your dog is anything other than very small.
This is something I ran into myself when I took Puglo to Thailand. We were able to fly to Bangkok, but after that, I had to arrange a private transfer to Chiang Mai because he couldn’t come in cabin on any of the domestic airlines. It definitely made the trip more complicated and showed me how limited the options can still be in this part of the world.
That said, there are a few airlines in Asia that do allow dogs in cabin, and I do think this region will improve over time as pet culture continues to grow. The Philippines in particular seems to be moving in a more pet-friendly direction, with some airlines now allowing higher weight limits and even emotional support animals.
Here are some Asian airlines that allow dogs in cabin:
Australian airlines that allow dogs in cabin
Australia is by far one of the strictest regions when it comes to flying with pets. Right now, there is only one airline that allows pets in cabin, and that policy was only introduced recently. At the moment, Virgin Australia only allows pets in cabin on select routes, so the options are still very limited.
I haven’t traveled around Australia with Puglo, but compared to other regions, this is definitely one of the hardest places to travel internationally with a dog, especially because of their mandatory 30-day quarantine if you are coming from abroad. That said, I’m hopeful this is a sign that things are starting to improve and that more pet-friendly options may follow in the future.
Here is the airline currently allowing pets in cabin in Australia:
Airlines that allow large dogs in cabin
One of the most encouraging changes in pet travel over the last few years is the rise of airlines and charter services that allow dogs of any size to fly in cabin. These are not traditional commercial airlines. Most are private or public charter style services that make the experience more accessible by selling individual seats, though they are still much more expensive than a regular airline ticket.
Companies like K9 Jets, BARK Air, RetrievAir, and TuscanHound Air all position themselves around in-cabin travel for larger pets, while JSX also allows many pets in cabin and says customers can bring medium to large dogs, subject to its policy.
I think this is a great option for people relocating or anyone who does not want to put their dog in cargo. It is still a premium choice, but it feels like a really positive sign for the future of pet travel, especially as more routes become available and more companies enter the space. BARK Air has already expanded its route network further in 2026, which suggests demand is there.

What to check before flying with a dog in cabin
Before booking a flight with your dog, there are a few important things to check since airline pet policies can vary a lot. Even if an airline says it allows dogs in cabin, the details can make a big difference in whether your dog is actually accepted at check in.
Carrier size requirements
This is one of the biggest things airlines look at. Your dog’s carrier usually needs to fit under the seat in front of you, and your dog should be able to lie down, turn around, and sit or stand comfortably inside.
I always recommend checking the exact carrier dimensions listed by the airline before booking. If you’re looking for one, here is my list of airline approved carriers.
Weight limit
Some airlines have a maximum combined weight for your dog and carrier, while others care more about whether the carrier fits under the seat. In regions like Europe and Asia, weight limits are often much stricter than in the U.S. or Latin America.
Route restrictions
Not every airline allows pets on every route. Some only allow dogs in cabin on domestic flights, while others may restrict pets on certain international routes or to specific countries. Some countries like the United Kingdom and South Africa restrict dogs from flying in cabin into the country.
Breed restrictions
Some airlines have breed restrictions for fighting dogs. Even if they allow these breeds in cabin, it is always worth double checking since the policies can be stricter for checked or cargo travel.
Pet fee
Most airlines charge a pet fee for dogs flying in cabin, and this can vary quite a bit. It is a good idea to check both the fee and whether it is charged per flight segment.
Number of pets allowed per flight
Many airlines only allow a small number of pets in cabin on each flight. That means even if the airline is pet-friendly, your dog may not be accepted unless there is space. Always call to add your dog to the flight as soon as you book your flight.
Check-in agent discretion
This is the part a lot of people do not realize. Even if your dog technically meets the requirements on paper, the final decision often comes down to the check-in staff. If your dog looks too tall, too cramped, or not calm enough in the carrier, you could still run into issues.
Destination country requirements
The airline policy is only one part of the equation. You also need to make sure your destination country allows dogs to enter and that you have the right paperwork, vaccinations, and health certificates.
That’s why I always recommend researching both the airline’s pet policy and the entry requirements for the country before booking anything. I cover how do all of this in my dog travel course.
Tips for getting your dog accepted at check in
Even if your dog technically meets the airline’s pet policy, there is often still some room for discretion at check in. Over the years, I’ve learned that the way you prepare can make a big difference in how smoothly the process goes.
Make sure your dog is comfortable in the carrier
This is one of the biggest things staff will look at. Your dog should be able to lie down, turn around, and look comfortable inside the carrier. If they look cramped, anxious, or too tall, you are more likely to run into issues.
Use the right carrier
A flexible soft sided carrier usually gives you the best chance of fitting under the seat while still keeping your dog comfortable. I also find that carriers with good ventilation and structure tend to look more airline appropriate at check in. These are the carriers I personally recommend.
Know the airline’s rules before you arrive
Do not rely on the check in staff to explain the policy to you. Before heading to the airport, make sure you know the airline’s size requirements, pet fee, and any route specific restrictions. I also like to keep the airline’s pet policy pulled up on my phone just in case.
Reserve your dog’s spot in advance
Many airlines only allow a limited number of pets in cabin on each flight. Even if the airline allows dogs, your pet may not be accepted unless you have added them to your reservation ahead of time.
Keep your dog calm before check in
A calm dog makes a much better impression than one barking, whining, or trying to climb out of the carrier. I try to make sure Puglo has had a chance to go to the bathroom and get some movement before we arrive at the counter so he is more settled.
Do not overpack the carrier
It can be tempting to fill the carrier with blankets, toys, and extras, but too much padding can make the space look smaller and more cramped. I try to keep it simple so there is no question that Puglo has enough room.
Give yourself extra time
Traveling with a dog usually means a few extra steps at the airport, and it is much easier to stay calm when you are not rushed. Getting there early also gives you more breathing room if the staff want to inspect the carrier or ask questions.
Have your documents ready
Have all of your documents ready to go. If your route requires paperwork like a health certificate, import permit, rabies titer test, or vaccine records, keep everything organized and easy to access at check in. Being prepared helps the process go more smoothly and shows the staff that you know what you’re doing.
Be polite and confident
Check in staff have a lot of discretion, and in my experience, being friendly, calm, and prepared goes a long way. If your dog meets the requirements and you know the policy, it helps you handle the interaction with more confidence.
Have a backup plan
Even when you do everything right, things can still be unpredictable. I have personally been denied once because staff said Puglo was too tall for his carrier, even though we had flown many times before. It is frustrating, but it reminded me that having a backup option or flexible mindset is always a good idea when flying with a dog. Your credit card insurance may be able to cover you if you are denied.
The more prepared you are, the better your chances of having a smooth check in experience.
FAQ: Airlines that allow dogs in cabin

Which airline allows you to buy a seat for your dog?
On mainstream airlines, pets usually do not get their own seat and must stay in a carrier under the seat in front of you. Pet-friendly airlines like BARK Air allow you to buy your dog a seat.
Can my pet fly in cabin on United?
Yes, United allows cats and dogs to fly in the cabin if there is space available and your pet is small enough to fit comfortably in an approved carrier.
How can I fly with my dog internationally?
Start by checking both the airline’s pet policy and your destination country’s entry rules, then work with a USDA-accredited vet on any vaccines, tests, and health certificate requirements. If you are returning to the U.S., CDC paperwork may also be required depending on where your dog has been.
Can a 25 lb dog fly in a cabin?
Sometimes, but on most commercial airlines in the U.S. the bigger issue is not the number on the scale, it is whether your dog can fit comfortably in a carrier under the seat. For many 25 lb dogs, commercial in-cabin options are limited.
Which airline is most pet friendly?
Specialty operators like BARK Air or JSX are often more pet-friendly than traditional commericial airlines.
What is the largest size dog that can fly in a cabin?
On most commercial airlines, only small dogs that fit under the seat in a carrier can fly in cabin. For larger dogs, operators like BARK Air and K9 Jets welcome dogs of all sizes and breeds.
Do dogs’ ears hurt when flying?
Some dogs may feel pressure changes during takeoff and landing, just like people do, but it is usually temporary. Keeping your dog calm and giving them a chance to swallow naturally can help.
What dog breeds are not allowed to fly?
It depends on the airline, but brachycephalic breeds like pugs, French bulldogs, and bulldogs are not allowed to fly in cargo, only in cabin.
Can I fly with my dog if I buy them a seat?
Usually not on standard commercial airlines, because most still require pets to travel in a carrier under the seat.
What is the best way to fly with a dog?
For most people, the best option is a direct flight on a pet-friendly airline where your dog can stay in cabin in a comfortable carrier. If your dog is too large for standard in-cabin travel and you want to avoid cargo, a charter or semi-private option is usually the best fit.
Finding airlines that allow dogs in cabin
Flying with a dog can feel overwhelming at first, especially when every airline has different rules and the policies seem to keep changing. But the good news is that there are more options out there than most people realize, and once you understand what to look for, it gets much easier to find an airline that works for both you and your dog.
For me, traveling with Puglo has definitely taken more planning, flexibility, and research, but it has also been so worth it. Whether you’re looking for the best commercial airline, trying to figure out if your dog will fit in cabin, or exploring options for a larger dog, I hope this guide has helped make the process feel a little less overwhelming.
