A trained service dog can travel with you almost everywhere: hotels, Uber and Lyft, taxis, Amtrak, Greyhound, city buses and cruise ships all have to accept it, and none of them may charge you a pet fee for it. An emotional support animal is different. Outside a few state and company exceptions, it travels as a pet, under pet rules and pet fees. No vest, ID card or registration changes either answer.
Which law covers which kind of trip?
Travel is covered by several federal rules at once, and each one uses slightly different words. That is why the answer to "can my dog come?" changes depending on how you are getting there:
- Hotels, restaurants, attractions and theme parks are public accommodations under Title III of the Americans with Disabilities Act (ADA). The service dog rules are in 28 CFR 36.302(c).
- Taxis, rideshare, buses and trains fall under the ADA's transportation rules. 49 CFR 37.167(d) says: "The entity shall permit service animals to accompany individuals with disabilities in vehicles and facilities." Amtrak is covered as intercity rail under ADA Title II.
- Cruise ships that pick up passengers at a U.S. port are covered by the Department of Transportation's passenger vessel rule, 49 CFR Part 39, and the Supreme Court held in Spector v. Norwegian Cruise Line (2005) that cruise ships are public accommodations.
- Planes have their own law, the Air Carrier Access Act. See flying with a service dog.
One wrinkle: the ground-transport definition of a service animal in 49 CFR 37.3 is not limited to dogs, while the Title III definition that hotels and parks follow is dogs only (with a separate rule for miniature horses).
What can staff ask on a trip?
Almost everywhere you travel, the same two questions apply when it is not obvious what your dog does:
- Is the dog a service animal required because of a disability?
- What work or task has the dog been trained to perform?
Staff may not ask about your disability, ask for documents, or ask the dog to demonstrate its task. Uber, Lyft and Airbnb repeat those limits in their own published policies, and the Federal Transit Administration says transit agencies "cannot have a policy requiring riders to provide documentation for their service animal before boarding". Amtrak says its personnel "may ask what active task(s) the service animal performs". The full rules are in what businesses can ask about a service dog.
Two exceptions to the "no documents" rule: airlines may require the DOT Service Animal Air Transportation Form, and cruise lines ask for health and vaccination records because ports of call set their own animal entry rules.
Can you be charged extra for a service dog when you travel?
No surcharge, but you can be charged for real damage. The ADA rule for public accommodations says a business may not charge a "surcharge, even if people accompanied by pets are required to pay fees", and that "if a public accommodation normally charges individuals for the damage they cause, an individual with a disability may be charged for damage caused by his or her service animal." The DOJ FAQ applies this to hotels directly: no cleaning fees for hair or dander. Uber and Lyft both say no cleaning or extra fees for a service animal, and Airbnb hosts may not charge pet or cleaning fees for one.
Can an emotional support animal travel with you?
Usually as a pet, not as a service animal. The ADA does not cover emotional support animals, so hotels, rideshare drivers, trains and parks can apply their normal pet rules. What that means in practice, from each company's own policy:
- Hotels: the hotel's pet policy applies, including pet fees and pet-room limits.
- Airbnb: hosts may decline or charge pet fees, except that hosts in California and New York must accommodate ESAs for Homes reservations.
- Lyft: pets can use a Pet ride for an additional fee.
- Amtrak: an ESA "is subject to the same requirements as a pet": 20 pounds including the carrier, trips up to 7 hours on most routes, and a fee.
- Greyhound: no ESAs. FlixBus, its sister brand, does allow them.
- Cruises: Carnival, Royal Caribbean and Norwegian all say they do not accept emotional support dogs.
- Disney parks: ESAs are not allowed in the parks; at Walt Disney World they are allowed only at designated pet-friendly resort hotels.

Can a service dog in training travel?
Not under federal law. The ADA covers only dogs that are already trained, and the DOT air travel form says "service animals in training are not service animals" for flights. Cruise lines such as Carnival say dogs in training are not allowed aboard, and Amtrak lists "animals in training" among the animals that may not be passed off as service animals. Some states protect trainers on the ground: Nevada, for example, bars public conveyances from charging a fee or deposit for a "service animal in training" (NRS 706.366). See service dogs in training for the state picture.
What to pack: documents and gear
For a trip within the United States, the list is short:
- The DOT form, if any leg is a flight.
- Your dog's rabies certificate and local license, since service dogs follow the same licensing and vaccination rules as every other dog (DOJ FAQ, questions 18 and 19).
- For cruises and trips abroad: the vaccination records, microchip details, health certificates and CDC Dog Import Form receipt the cruise line or country asks for. See international travel with a service dog.
A vest, a patch or a wallet card is optional. Some handlers carry wallet cards that quote the two questions so a driver or front desk clerk can read the rule instead of arguing about it. None of that is a travel document, and no one is required to accept it.
What to do if you are refused
Stay calm, state the two questions and your answers, and ask for a manager or supervisor. If you are still refused, write down the date, time, place, names and what was said. Then use the right channel: the company's own reporting process (Uber, Lyft and Airbnb all publish one), your state civil rights agency, or a complaint to the U.S. Department of Justice at ADA.gov. Rideshare refusals are taken seriously: the Justice Department sued Uber in 2025 over refused rides for passengers with service dogs, and that case is still pending.

Common questions
Do hotels, trains and rideshare have to accept my service dog?
Yes, if your dog is individually trained to do a task related to your disability. Hotels are public accommodations under the ADA, and taxis, rideshare, buses and trains are covered by the ADA's transportation rules.
Can I travel with my emotional support animal?
Usually only as a pet, under each company's pet rules and fees. Airbnb homes in California and New York are one exception; see Airbnb and Vrbo rules.
Do I need a vest or ID card for my service dog to travel?
No. The DOJ says the ADA does not require a vest, ID tag or specific harness. The only travel paperwork an airline may require is the DOT form.
Can a service dog in training travel with me?
Not under federal law. Some states protect trainers on buses, taxis and in public places, so check your state's rules.
Can I be charged for my service dog on a trip?
Not a fee or deposit for having the dog. You can be charged for actual damage the dog causes if other guests or riders pay for damage too.
