If you have read my previous post on the differences between service dogs, therapy dogs, and emotional support animals, you already know that these three categories are not the same thing legally. That distinction matters every day, but it matters most when you travel.
The rules change depending on where you are going, how you are getting there, and what kind of animal you have. I have worked with handlers preparing dogs for public access for over 25 years, and the travel piece is where I see the most confusion and the most avoidable conflict. So let's go through it clearly.
Flying: The Rules Have Changed
Air travel is governed by the Air Carrier Access Act (ACAA), not the ADA. That is an important distinction because the ACAA has its own definitions and its own documentation requirements.
Here is the current state of things for each category:
Service Dogs: Airlines are required to recognize dogs as service animals and accept them for transport on flights to, within, and from the United States at no additional charge. U.S. Department of Transportation Before your flight, you will need to complete the DOT's Service Animal Air Transportation Form and submit it to the airline in advance. Most airlines have a link on their website. If you booked within 48 hours of departure, you can bring the form to the airport counter.
Airlines may deny transport to a service dog if it is too large or heavy to be accommodated in the cabin, poses a direct threat to the health or safety of others, causes a significant disruption, or violates health requirements for a destination country. U.S. Department of Transportation
Breed restrictions do not apply. A service dog cannot be denied simply because of its size or breed under federal law.
Therapy Dogs: Therapy dogs have no special status under the ACAA. They travel as pets. That means standard airline pet fees apply, carriers are required for in-cabin travel if the dog is small enough, and larger dogs may need to travel in cargo. If you do therapy dog work and travel to your facilities, plan accordingly and check each airline's pet policy before booking.
Emotional Support Animals: As of January 2021, the Department of Transportation revised its regulations to remove ESA protections under the ACAA. Most major U.S. airlines now only recognize trained service animals for free cabin access. ESAs may still fly but typically as pets, subject to each airline's pet policies. Service Dog Certifications This usually means paying pet transportation fees, often $95 to $125 each way, and following carrier size restrictions. Service Dog Certifications
This was a significant change that many ESA owners still do not know about. If your dog qualifies as a psychiatric service dog because it is trained to perform a specific task related to your mental health condition, that is a different classification and still carries full ACAA protections.

Hotels and Accommodations
Service Dogs: Under the ADA, hotels cannot require any documentation, certification, or papers for a service dog. If it is not immediately obvious that the dog is a service animal, hotel staff are limited to asking only two specific questions: Is the animal required because of a disability? What work or task has the animal been trained to perform? ESA Pet No pet fees can be charged for a legitimate service dog. Hotels can charge for actual damage caused by the animal, but not for its presence.
Therapy Dogs: No special hotel protections exist for therapy dogs. They are treated as pets. Some hotels are pet friendly and will accommodate them, but that is a policy decision by the property, not a legal requirement. Always call ahead.
Emotional Support Animals: Unlike service animals, ESAs do not have guaranteed public access rights in hotels. The Fair Housing Act applies to housing, not short-term hotel stays, which is why hotels are legally permitted to deny access to ESAs, charge fees, or impose restrictions. ESA Pet Many pet-friendly hotels will voluntarily accommodate ESAs, but verify the policy before you arrive.

Public Transportation: Ground Travel
For trains, buses, rideshares, and local transit, the rules differ from air travel:
Service Dogs: A person traveling with a service animal cannot be denied access to transportation, even if there is a no-pets policy. No additional fees can be charged, and the person does not have to provide advance notice that they will be traveling with a service animal. The laws apply to both public and private transportation providers and include subways, fixed-route buses, paratransit, rail, light-rail, taxicabs, shuttles, and limousine services. ADA National Network
This includes Uber and Lyft. Both companies' policies require drivers to accommodate service animals, though refusals still happen. If you are denied, document it and report it.
Therapy Dogs and ESAs: No federal public access protections apply on ground transportation. Access is at the discretion of the provider. Some will accommodate, some will not. Again, call ahead.

International Travel: A Different Rulebook
If you are traveling internationally with a service dog, U.S. law stops at the border. Every country has its own rules.
Some things to know:
- Many countries require health certificates, proof of vaccination, and advance documentation before a service dog can enter
- Some countries have quarantine requirements
- U.S. airlines traveling to foreign countries are subject to the requirements of that foreign country regarding acceptance of service animals. Not all countries permit service animals from other foreign countries. Check to ensure whether your destination country permits your animal and any other requirements to enter and exit legally. U.S. Department of Transportation
- Research your destination country's specific requirements well in advance. Do not assume U.S. protections follow you overseas.

How to Prepare Your Dog for Travel
This is the part most people skip, and it is the part that matters most.
A dog can have full legal access and still not be ready to travel. Travel is high stimulation — airports, crowds, unfamiliar smells, confined spaces, irregular schedules. A dog that is solid in its training at home or in a controlled environment may respond differently in those conditions.
Before traveling with any dog, service, therapy, or ESA, I recommend working on:
- Calm, neutral behavior in crowded and unfamiliar environments
- Sustained focus on the handler under distraction
- Comfort in confined spaces for extended periods
- Reliable response to commands even when the handler is stressed
- A solid foundation of public access exposure before the trip, not during it
The goal is a dog that the handler does not have to manage. When you are navigating a busy airport, dealing with check-in, security, and boarding, your attention is split. Your dog needs to carry itself.
If you are not sure whether your dog is ready for travel, that is exactly the kind of question I work through with clients here at Must Love Dogs™ in Weatherford, Texas. Public access preparation is one of my core training areas, and honest assessment is part of what I bring to every session.
Being Prepared Matters, Because Your Dog Being With You Matters
Support animals exist because the bond between a person and their dog is real, documented, and powerful. We know that. You know that. And if you are someone who relies on a service dog, a therapy dog, or an emotional support animal to navigate the world, that relationship is worth protecting and preparing for.
Travel should not be the thing that gets in the way of that. We hope this guide helps you show up prepared, know your rights, and focus on what matters — you and your dog, wherever you are going.
If you are heading into a hard season and your dog is part of how you get through it, you are not alone in that.
