Airlines That Allow Large Dogs in the Cabin for International Travel

Last Updated: October 16, 2025

Flying internationally with a large dog in the cabin is highly restrictive on major commercial airlines. It is typically possible with specialty pet charter services. The vast majority of airlines allow passengers to travel with their small vaccinated dogs under a certain weight limit so that they can fit in the carrier under the seat in front of them. 

However, there are exceptions for service animals, and a few specialized airlines such as BARK Air, K9 Jets, Tradewind Aviation, JSX (JetSuiteX), and Aero Airlines cater to larger pets. So, if you’re wondering which airline to book so that you can fly stress-free with your large dogs, then we’ve got you covered. In this guide, we break down the specific pet-friendly charters and private airlines, their specific commercial airline policies, and the necessary steps that you need to know. 

Pet-Friendly Airlines That Allow Large Dogs in the Cabin

Traveling with your furry companion can be fun but tricky-especially when your dog is too large for a typical under-seat carrier. While most airlines allow small pets, there are some exceptions where large dogs are allowed, not in the in-cargo but in the cabin. These pet-friendly airlines are:

  • BARK Air: This new airline allows dogs of all sizes and breeds in the cabin. BARK Air aims to make the flying experience comfortable for your dogs in the air and on the ground. It is the only dog-first travel service that currently offers flights on specific routes between the New York City area, Los Angeles, and London.    
  • K9 Jets: K9 Jets allows large dogs as they have no size, weight, or breed restrictions. One large dog over 51 lbs is permitted per purchased seat by the passengers. Dogs fly in the cabin with their owners, with assigned seats to ensure a stress-free environment.  
  • Aero Airlines: Aero Airlines allows large dogs to fly in the cabin, but you must purchase an extra seat for the pet. It has a limit of two large dogs over 65 pounds per flight, with a total of five pets allowed per flight. 
  • Tradewind Aviation: Tradewind Aviation allows large dogs in the cabin. But, unlike the others, they have some specifications, like your dog must be booked in advance, in a healthy and well-groomed manner, and be in an airline-approved carrier. The weight limit of the dog should not exceed 21 lbs in the cabin, and the overall weight (including the dog and its carrier) should be under 100 lbs. 
  • JSX (JetSuiteX): JSX permits medium-to-large dogs to be transported by customers in-cabin. It allows dogs weighing up to 79 pounds to fly in the cabin by purchasing an extra seat for them, which is leashed and remains on the floor in front of their owners’ seats. However, you need to submit a printed pet acceptance form at the time of check-in, confirming that your dogs are well-behaved and non-aggressive.

Essential Tips for Flying Large Dogs Internationally

Flying with a large dog across borders can be smooth and stress-free if planned the right way. Unlike small pets, big dogs require a bit more prep, paperwork, and patience. These tips will make your international journey comfortable and compliant for both you and your dog. 

  • Check breed and destination country rules
  • Get your dog’s up-to-date vaccinations and certificates.  
  • Train your dog for cabin calmness.
  • Book your pet’s seats early and confirm the same with the Airline. 
  • Always carry a small travel kit with all the essentials for your pet (water, treats, waste bags, and wet wipes).  

Once you tick all the checklists given above, you’re ready to fly with your large furry companion by your side.

Estimated costs and what you can expect when traveling on these flights with large dogs. 

Last but not the least, when it comes to flying internationally with large dogs, cost is one of the massive factors to look out for. Prices vary very widely depending on the airline, travel route, and whether your dog is flying as a cabin companior, or carrier and their size. 

Knowing what to expect helps you budget realistically and avoid hidden surprises. Let’s understand how each of the international flights have different budgets and what you can expect:

  • BARK Air: Domestic flights start around $6000 and flying in international flights cost approximately $8,000 for a one-way trip for one human and a dog. This flight offered international routes like New York to London, Paris & Lisbon for your large dogs. 
  • Tradewind Aviation: Prices differ depending on the date and the season, but when flying with large dog, the one-way flights will cost you between $9000 and $15000. Tradewind Aviation does not currently offer international flights. 
  • K9 Jets: The base cost is approximate $8,000 to $10,000 per seat for a large dog on popular routes like US to Europe. Some international flights may cost you up to $25,000. This includes one seat typically accommodating one large dog. 
  • Aero Airlines: It allows large dogs over 65 lbs to fly in cargo. Although there is no fixed fares for large dogs but that depends on their specific policies, but you can expect to pay between $2000 and $10,000 and for international flights, it can increase, ranging from $ 10,000 to $ 50,000.   
  • JSX (JetSuiteX): For this flight, a large dog must occupy a second seat which costs you around the price of a second ticket, ranging from $500 and up one-way plus the cost of the ticket for yourself. 

This proves that you can expect very high fares when flying with large dogs, plus the more you ask for pampering and pet centric services, the more you pay. 

It is therefore advised that you should always book early as there are limited seats (except for BARK Air as it is solely pet-focused airline). But still you should book in advance if you want your dog to fly in cabin.
