What is a Psychiatric Services Animal (PSA) Letter for Travel?

A PSA Letter for Travel, certified by a licensed health professional, allows a service dog to accompany its owner on flights at no additional charge. It is created by a certified mental health professional after a therapy session to assess applicability. It confirms that you have a disability or condition that a properly trained animal will service. 

This means you can legally travel with a psychiatric service animal in the cabin at no extra cost.

How Do I Get a PSA Letter for Travel?

Obtaining a Free My Paws PSA letter for travel through Felicitails is simple. Start with our short questionnaire to be matched with one of our in-house certified therapists. If you qualify, you'll typically receive your letter within 24 hours.

What Conditions Qualify for a PSA Letter for Travel?

To qualify for a PSA letter, a licensed mental health professional will need to assess your needs and create a prescribed treatment plan for a relevant mental or emotional health disability such as depression, ADHD, autism, or an anxiety disorder of which requires physical assistance of an animal such as tactile pressure.

Can I use a Free My Paws Travel Letter to fly with my Emotional Support Animal (ESA)?

No, you can’t use an ESA Travel Letter from Free My Paws to fly free of charge with your ESA on Allegiant Air under the same conditions as a service animal. This is due to recent changes which mean that virtually no airline will accept ESAs. However, you may be able to fly with your ESA subject to the same terms and fees applied to regular pets.

What's the Difference Between an Emotional Support Animal and a Psychiatric Service Animal?

ESAs and PSAs (Psychiatric Service Animals) help their human companions similarly. Both help reduce stress in anxiety-causing situations. 

While the qualifying processes for an ESA and a PSA are similar, service animal training focuses on specific tasks. Depending on your needs, your PSA may perform a few critical tasks, for example: 

  • Detecting early signs of a panic attack 
  • Applying calming tactile pressure 
  • Fetching medication
  • Signaling to others that you need space
  • Seeking outside assistance if you're in danger

Your PSA will need to be trained to meet the required standard. The effective and affordable Basic Obedience Program from Free My Paws is a great starting point. Click here to find out more.

How to Fly With a PSA on Allegiant Air

It’s essential to obtain and submit all the required documentation in advance of your flight.

You must comply with Air Canada’s  service dog policy and submit a completed US DOT Service Animal Air Transportation Form

While the US DOT Service Animal Air Transportation Form is the essential requirement, and you will need to submit it to the airline in advance - generally at least 48 hours before your flight, you'll also need to complete the airline's application to fly with your PSA.

The Free My Paws therapist-certified Psychiatric Service Animal letter for travel verifies that you'll need your service animal on your flight.

The three documents you'll need to complete and submit to the airline to fly with a PSA:


U.S. DOT Service Animal Transport Form

Air Canada's Service Animal / Dog Policies

Each passenger may have up to two Service Animals on flights to and from the United States. Within Canada and to other destinations, each passenger may take only one Service Animal. 

Your service animal cannot sit on your knee during an Air Canada flight. Service Animals must be on a leash, wear a harness, or be tethered throughout the journey.

You're good to go if your animal companion is a PSA (Psychiatric Service Animal) and you have the proper DOT documentation.

The DOT form requires you to accept responsibility for any damages the animal may cause.

Allegiant Air’s PSA Travel Letter Policies

Allegiant Air requires that all passengers accompanied by a PSA present three fully completed forms at least one hour prior to departure.

These are: 

  • Veterinary Health Form
  • Letter from a certified Mental Health Professional
  • Animal Behavior and Responsibility Form

All three forms can be found here. 

Allegiant Air, in common with other airlines, has the right to ask questions about what tasks the PSD performs to support your disability. The easiest way to prove that your psychiatric service dog is a service animal is to provide the airline with an official PSD letter from Free My Paws, through Felicitails.

How Much Advance Notice Does Allegiant Air Require?

Allegiant Air requires 48 hours advance notice before you fly with an animal.

Contact the Allegiant Air Medical Assistance Desk about your PSA at least 48 hours before your flight departs. Notify them that you have a service dog and ask for additional floor space for the dog if required. 

You can call the Medical Assistance Desk at 702-505-8888.

What About Longer Flights with a PSA?

If your flight lasts eight hours or longer, you must complete the US DOT's Service Animal Relief Attestation Form.

You certify that your PSA will either not urinate or defecate on the plane, or that it can do so hygienically. 

Allegiant Air’s Breed Restrictions

While Allegiant Air doesn’t specify any restricted breeds on its website, the airline may deny boarding to an animal on the grounds of safety, size or behavior.

Air Canada has size requirements for pet carriers. The airline mandates that pet carriers are stored underneath the seats, so these requirements vary by aircraft type. 

Your pet carrier must not exceed these dimensions:


Are Pet Carriers Part of  Allegiant Air’s Baggage Allowance?

Bringing a pet carrier will count as one of the two allowable items for passengers. In other words, if you have a pet carrier, you can bring either a personal item or a paid carry-on bag, but not both.

Additional useful advice for flying with your Psychiatric Service Animal

  • If they’ve never flown before, don't just assume your PSA dog can handle airline travel. Check with your dog's veterinarian and trainer to discuss travel suitability and options
  • US DOT and airline service animal rules can change anytime, so check for any updates before booking your ticket.
  • Confirm any quarantines, restrictions, or embargoes before your flight.
  • Have ready access to your documents to make it easy for airline staff to check them. You'll save time and hassles during the check-in process.
  •  Have written descriptions of the tasks performed by your service dog ready for checking.
  • Exercise your dog before heading to the airport.
  • Inform airport security that your dog is a service dog.
  • Cooperate with airport staff and keep your dog under control at all times.
  • Avoid overfeeding and overwatering your dog before your flight - offer them food and water as soon as possible after you land.

The ACAA and Your Right to Fly with a PSA

What Is the Effect of the ACAA (Air Carrier Access Act)? 

The ACAA prohibits discrimination based on passengers' disabilities and mandates airlines to offer accessibility features and facilities. These accommodations include ramps and mechanical lifts, adjustable armrests, easy-access restrooms, and facilities for mobility aids and service animals. 


Emotional Support Animals and the ACAA

The ACAA originally defined service animals as those trained to assist people with disabilities. However, a 2003 DOT policy update permitted ESAs inside airplane cabins. This change allowed eligible passengers to be accompanied by an emotional support dog, cat, or other animal in the cabin.

ESAs do not have to be trained to perform specific tasks. Their presence alone supports people dealing with anxiety, PTSD, OCD, depression, and other mental health conditions, but the animal does not provide a physical service to treat the ailment.

The 2003 DOT policy change didn't limit the species that could serve as ESAs. However, air carriers faced unique challenges as passengers brought animals they claimed were ESAs without legitimate documentation. 

This is one of the reasons that most airlines, including Allegiant Air, no longer allow Emotional Support Animals to fly with their owner in the cabin.

An ESA letter will not enable you to avoid the airline’s rules and fees for pet travel.

However, complying with the ADA, they permit Psychiatric Service Animals / Dogs (PSAs), which carry out functions similar to ESAs for people with mental and emotional support needs. 

Check out the ACAA guidelines here.

Service Animals / Dogs and the ACAA

As per the ACAA guidelines:

  • Your service animal must be allowed to accompany you in the space under the seat in front of you.
  • Your service animal must not block a space that must be clear for safety reasons (e.g. an aisle or access to an emergency exit).
  • Airlines do not have to upgrade you to a different class to accommodate your service animal.
  • Airlines do not have the right to refuse your service animal onboard because it makes other passengers or flight crew uncomfortable.
  • Your service animal must behave appropriately. An animal that displays disruptive behavior (ex. barking, snarling, running around, and/or jumping onto others etc.) will not be accepted as a service animal.


Contact the Felicitails Team at to discuss how our PSA Training Academy can assist in training your animal. Learn from the service animal experts and ensure your companion will behave nicely on their travels.
