7 Airlines Allowing Flying with Large ESA Dog [2023]

Flying with a large ESA dog is a little difficult nowadays, for a few reasons. Firstly, many airlines no longer accept emotional support animals as service animals, therefore they will often need to fly as standard pets. Secondly, some airlines that do permit flying with emotional support dogs, will only allow flying with small ESA dogs. Lastly, only a limited number of ESA dogs are permitted on board, per flight. 

The following airlines permit flying with a large ESA dog, with certain restrictions:

In this article we will outline which airlines allow flying with a large ESA dog, and outline the process of taking a ESA dog on a flight.

What are Emotional Support Animals (ESAs)?

In their most basic definition, ESAs are simply animals who provide their owners with therapeutic benefits. An ESA provides emotional support to their human through love and companionship. As anyone who has ever had a pet knows, animals have an incredible ability to connect with humans on a deep level. For many people, a beloved animal friend may be the first one a person goes to when they need someone to comfort them and talk to without judgement. This comes without the training that a service animal or therapy animal must go through.

Though they provide incredibly important services, emotional support animals are considered to be somewhere in between the realms of service or psychiatry animals and standard pets. So, while they don’t generally get the same legal rights as service animals, they do get some. This includes being able to fly with their owners, and being allowed to live in some ‘no-pet’ housing. 

It’s important to note that there is no official registry for ESAs, and no official certificate. Rather, in order to prove your animal is your ESA, you will need an official letter signed by a credited medical health practitioner.

BEWARE OF SCAMS! There are many websites offering ESA certificates for pets, in exchange for a fee. There is not such thing as an ESA certificate so stay clear of these websites.

Airlines Accepting Large Psychiatric Service Dogs

Psychiatric support dogs (PSDs) are not the same as emotional support animals (ESAs), in fact psychiatric animals have more legal rights than ESAs. However, it is possible in the right circumstances and with some effort to train an emotional support animal to become a PSD. 

The main difference between an ESA and a PSD is that a PSD must be trained to perform tasks related to the handler’s disability. These tasks include providing pressure therapy during moments of crisis, retrieving medication, helping the handler maintain daily routines, among many more. On the other hand, ESAs have no specific training requirements and alleviate symptoms of mental illness simply through their companionship. Furthermore, unlike ESAs, only dogs can serve as psychiatric service animals. 

All airlines flying to and from the United States allow psychiatric service dogs on their flights.

PSDs are allowed to board flights in the cabin free of charge. In order to fly with a psychiatric dog, you must submit a DOT’s Service Animal Transportation Form prior to your flight.

On the form, you must self-certify that your dog has been trained to perform tasks relating to your disability. PSD owners have a right to privacy and dignity: airlines are not allowed to ask what the passenger’s specific disability is, and they are now allowed to ask you to demonstrate the task your PSD has been trained to perform.

Furthermore, the form requires the name of the PSD’s trainer, which can be the owner (third-party training is not a requirement for PSDs). 

What is the process of flying with a large ESA dog?

The process of taking emotional support animals on an international flight is as follows:

  1. Obtain a medical assessment letter / ESA letter
  2. Obtain your pet’s pet passport
  3. Book flights and inform your airline you will be bringing an Emotional Support Animal
  4. Complete required forms

Obtain a Medical Assessment Letter / ESA Letter

It’s important to note that there are no official certificates and no official registration database for Emotional Support Animals. In order to fly with a large ESA dog, you will need an ESA letter, an official letter from a medical health professional.

Beware of scams! There are many websites popping up offering ESA Certificates in exchange for a fee – please avoid any websites offering this service. There is no such thing as an official ESA certificate or registry.

An ESA letter is a recommendation letter from a licensed medical professional stating your need for an ESA. Medical professionals include psychologists, therapists, psychiatrists or other duly-licensed and/or certified mental health professionals.

The letter must:

  • Clearly explain your need for an emotional support animal.
  • Be legitimate—i.e., on professional letterhead and written by a qualified physician and/or mental health provider.
  • Include your medical professional’s license number, as well as their signature and the date the letter was signed. 

If you don’t already have a mental health provider, you have two options:

  1. You can either make an appointment with one and get your letter that way, or;
  2. You can use an online ESA letter service, such as Emotional Pet SupportESA Doctors, or CertaPet. These services do charge, and you will be required to undergo a mental health evaluation before receiving your letter.

What qualifies you to own an emotional service animal?

To qualify for an ESA, a licensed medical health care professional will determine whether you have a disability and whether an ESA would help manage your symptoms. A “disability” for purposes of qualifying for an Emotional Support Dog means a mental health condition like depression or severe anxiety, phobias and PTSD that substantially limits one or more major life activities, like the ability to study, work, travel or sleep. 

Obtain your Emotional Support Animal’s pet passport

In order to fly with a large ESA dog, they must have a pet passport. 

The requirements for obtaining your ESA dog’s pet passport will differ depending on where you are travelling to and from. However it is likely that your dog will require the following:

  1. Microchip
  2. Animal health certificate
  3. Rabies vaccination
  4. Rabies titer test
  5. Additional vaccinations
  6. Parasite treatment

This is just a guide on what is required, please check the requirements for the specific country you and your ESA are visiting. 

a) Microchipping your ESA.

A microchip is a electronic chip that’s inserted under the skin of your dog. A microchip holds a number unique, and will be connected to a database with your contact details.

Not only is a microchip usually a requirement when getting a pet passport, it is in your best interest. If your ESA was to go missing, then you are far more likely to be reunited. 

Your ESA dog can get microchipped at your local vet or a charity, such as RSPCA.

Get your ESA microchipped BEFORE getting his/her rabies vaccinations. Often, vaccinations will not be valid if microchipped after.

b) Animal health certificate.

In order to export and import pets most countries will require an official animal health certificate issued by an accredited veterinarian.

Of course, it differs between countries, but most require the animal health certificate to be obtained within 5-10 days of travel. 

In most cases, your health certificate will also need to be endorsed by the country’s authority responsible for the import and export of animals. For example, if you are traveling from the US, you will need your documents endorsed by the USDA. Alternatively, if you are traveling from Canada, you will need to have your documents endorsed by CFIA.

c) Rabies vaccinations.

If you want your take an Emotional Support Animal on an international flight, it is mandatory that he/she has a valid rabies vaccination. This is a requirement for entering most countries.

Most countries require dogs to have their rabies vaccination between 30 days and 12 months prior to importing. However, this differs depending on your destination country. Furthermore, some countries recognise both 1 year and 3 year vaccinations, while others only accept 1 year vaccinations. 

You can get your pet’s rabies vaccination at your local vet, alternatively some charities offer this service for free or for a discounted price. 

d) Rabies titer test.

Some countries require pets to have a rabies titer test before entering, to show that your pet’s rabies vaccination was successful. This is often the case when you are traveling from a country that your destination country considers high risk for rabies.

The process for getting your pet’s rabies titer test is as follows:

  1. Your pet will have a blood sample taken at least 30 days after the rabies vaccination.
  2. Your vet will then send the blood sample to an approved blood testing laboratory.
  3. Your pet’s blood test results must show a rabies antibody level of at least 0.5 IU/ml.
  4. You must wait 3 months from the date the blood sample was taken before you travel.
  5. The vet will give you a copy of the test results.

e) Additional vaccinations.

Depending on where you are flying to, your ESA may also require additional vaccinations or treatments. Common required vaccinations include:

  • bordetella
  • distemper
  • hepatitis
  • leptospirosis
  • parainfluenza
  • parvovirus

f) Parasite treatment.

Many countries require that dogs are treated against internal and/or external parasites before importation. This includes treatment for fleas, tapeworm, ticks, nematodes and cestodes. 

Book flights and inform your airline you will be flying with a large ESA dog

It’s important to check that your airline allows flying with a large ESA dog, as many do not. If your airline does not allow flying with large ESA dogs, you will need to adhere to the airlines standard pet policies, which usually means flying as checked baggage. 

When booking your flight, it’s important to note that you may be restricted to sit in specific seats on the plane. Most airlines require that passengers travelling with ESAs sit in certain seats on the plane, particularly if they are large ESA dogs. Therefore, it is important to check these specific requirements, when booking your flight or reserving your seats. You will need to inform the airline of your dog’s breed, weight, length, height and width, so they can see if they have an appropriate area for you and your dog to travel in. 

Generally, you will need to inform the airline that you will be bringing an ESA, at least 48 hours before the flight. However, it is recommended that you inform them much further in advance. This is because quite often, only one service animal is permitted per flight. You want to ensure you can reserve your large ESA dog a spot. 

As well as providing your ESA letter, some airlines may also require you to complete a form. The document will state the address and jurisdiction of the health professional who approved your use of an ESA. Furthermore, it will state that you have a mental health related disability and are under the care of a health professional.

The amount of notice the airline will need, may differ between airlines. So, again, please check the policies before booking your flight. If you fail to give some airports and airlines sufficient notice, then your ESA may be checked into the kennel compartment of the plane.

Complete required forms

Airlines usually require you or your medical health professional to complete forms before taking emotional support animals on international flights.

Forms are usually required to verify that you have a mental health related disability, and that your ESA is essential for your well-being.  

Furthermore, a sanitation form is often required by airlines, in cases where your flight is over 8 hours long. This form states that during the flight, your service animal or ESA will not defecate or urinate for the duration of the flight. 

Check the airline policy of who you are flying with, to see which forms are required.

Tips for flying with a large ESA dog

1. Train your ESA to stay calm.

Your dog will need to stay calm on the flight otherwise they risk being sent into the cargo area of the plane. Being obedient to orders is a requirement when flying with a large ESA. Your large ESA dog will need to sit at your feet for the duration of the flight, so work on a strong sit-stay or lie down-stay. 

2. Exhaust your ESA before the flight.

Try to exhaust your dog by increasing the level of activity before your trip. A sleepy animal will be less prone to getting stressed out on the flight, and will be less likely to cause trouble on the flight.

3. Limit access to food and water before the flight.

Limit your dog’s access to food prior to the flight. Therefore, it’ll be less likely that they will need to ‘defecate or urinate’ on the flight.

Furthermore, some animals are more likely to experience motion sickness if they eat just before a flight. 

4. Familiarise yourself with the airport that you are departing from and arriving to.

Most airports will have a dedicated area for dogs and service animals to rest. In the U.S, it is actually a legal requirement for airports have pet-relief areas available for working animals and pets to rest. Take some photos of the airport maps, so you don’t have to wander around on the day trying to find a resting place.
