Flying with Your Service Dog
Last updated March 2026
Below we've compiled a list of service dog policies from popular air carriers in the US for your convenience. As these policies may change from time to time, we encourage you to double check with your airline before departure to avoid any last-minute surprises.
Important: As of January 2021, under the U.S. Department of Transportation's final rule on service animals, all major US airlines only accept trained service dogs — emotional support animals (ESAs) are no longer recognized as service animals for air travel and are subject to standard pet fees and restrictions.
In general, service dogs that accompany you on the aircraft in the cabin are expected to be well-behaved, quiet, and may not encroach on the space of another passenger. Please also be mindful of other passengers who may be allergic to dogs and be ready to switch seats should airline staff make such a request. Very large service dogs may have to fly in a kennel and checked, so if you are in that situation we encourage you to check with your airline before you book a ticket.
Required DOT Forms
The U.S. Department of Transportation requires the following forms for all service dog air travel (updated September 2024):
DOT Service Animal Air Transportation Form (PDF)
DOT Service Animal Relief Attestation Form (PDF) (required for flights scheduled for 8 hours or more)
American Airlines
Fully-trained service dogs may fly in the cabin at no charge if they meet the requirements.
A service animal is defined as a dog that's individually trained to do work or perform tasks for the benefit of a qualified individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability, including but not limited to:
- Visual impairments
- Deafness
- Seizures
- Mobility impairments
- Post-traumatic stress disorder
Please note, service animals in training, emotional support animals, and comfort animals may travel as pets, not as service animals. All requirements and applicable fees will apply.
Forms and advance notice
To travel with a service animal on flights operated by American, you must submit the U.S. Department of Transportation (DOT) Service Animal Air Transportation Form attesting to the animal's health, training, and behavior to the Special Assistance Desk at least 48 hours before your flight. We'll notify you upon document approval.
You can complete the form at the airport if you bought your ticket within 48 hours before the flight. Be sure to arrive early.

On Delta flights, trained service animals are expected to be seated in the floor space below a customer's seat or seated in a customer's lap — they are not permitted to occupy seats. Trained service animals and their associated items travel for free. The size of the animal must not exceed the "footprint" of the passenger's seat.

NOTE: If you encounter any issues with your trained service animal while at the airport or on board, please ask to speak to a Complaint Resolution Official (CRO). These trained Delta representatives are ready to assist passengers with accessibility needs and protect your rights when you travel by air.
Trained Service Animals
Trained service animals are defined as only dogs specifically trained to assist a person with a disability. Customers may travel with up to two trained service animals. Trained service animals must be properly cleaned and must not have a foul odor.
Customers must submit the U.S. DOT Service Animal Air Travel Form for validation prior to their flight attesting to the animal's health, training and behavior.
To protect public health, Delta Air Lines requires all dogs including service animals to be current on all vaccinations. Dogs can be vaccinated against rabies at a minimum of 12 weeks (three months) of age and must wait an additional 30 days for the vaccine to become effective.
For travel booked 48 hours or more prior to departure, customers must submit this documentation in advance for validation through the Accessibility Service Request Form located in My Trips.
For travel booked less than 48 hours prior to departure, customers may present the U.S. DOT Service Animal Air Travel Form at the check-in counter or departure gate.
For flights scheduled for 8 hours or more, customers must also submit a DOT Relief Attestation Form, attesting that the dog will not relieve itself in the aircraft or can do so in a sanitary manner.

International Travel
International destinations, even on US based carriers, may have different policies and may not always conform to the guidelines set forth by the ADA. Some countries require proof of vaccination, specialized vet forms and documentation, or may forbid service dogs from entering at all due to quarantine or other policies. We strongly encourage you to call your airline in advance to check their policy before attempting to board your international flight with a service dog.
