Flying with a dog takes more planning than driving. Each airline sets its own rules for pets, and those rules can change. Requirements also depend on your destination, especially for international travel. Before you book, it is worth getting clear answers so there are no surprises at the airport. Always confirm details directly with the airline and with the official government sources for your destination.
Is Your Dog Eligible to Fly?
Start with the basics. Airlines may limit pet travel based on the dog’s size, age, breed and health. Some airlines do not accept certain breeds, such as short-nosed breeds, in some or all travel options because these dogs can have breathing difficulties. Puppies may need to be a minimum age.
- Does the airline accept pets on this route?
- Are there breed, size or age restrictions?
- Does my dog need to fit in a carrier under the seat to travel in the cabin?
- Are there limits on how many pets are allowed on each flight?
Because many airlines limit the number of pets per flight, it is often wise to call and reserve a spot for your dog when you book your own ticket.
Cabin, Cargo or Neither?
Small dogs who fit comfortably in an approved carrier under the seat may be able to fly in the cabin on some airlines. Larger dogs may only be able to travel as checked baggage or cargo, if the airline offers it, and many airlines have reduced or eliminated those options. Some airlines also restrict pet travel in very hot or cold weather.
Talk honestly with your veterinarian about whether flying is a good choice for your dog, especially in cargo. For some dogs, driving or leaving them with a trusted caregiver may be the better option.
Carrier Requirements
Airlines usually specify the size and type of carrier allowed. Ask for exact dimensions and whether soft-sided carriers are acceptable for the cabin. For cargo travel, kennel requirements are often detailed and strict. Your dog should be able to stand, turn around and lie down comfortably in the carrier.
Fees and Paperwork
Pet fees vary by airline and can be significant. Ask what the fee is, whether it is charged each way and what it covers. Then ask about paperwork.
- Does the airline require a health certificate, and how recently must it be issued?
- What vaccinations are required?
- What does my destination require?
For travel within the United States, the airline and your destination state may have requirements. For international travel, rules can be extensive and may require planning months in advance. The USDA Animal and Plant Health Inspection Service maintains pet travel information at aphis.usda.gov, and destination countries have their own official guidance. Bringing a dog into the United States has its own rules too, which the CDC explains at cdc.gov.
Service Dogs and Emotional Support Animals
Rules for service dogs and emotional support animals on flights have changed over the years. If this applies to you, check the airline’s current policy and the U.S. Department of Transportation’s guidance at transportation.gov before you travel.
Once you have answers in writing, keep them with your travel documents. Clear information ahead of time is the best way to make the trip calmer for you and your dog.
