To fly a trained service dog on United you must fill and submit the U.S. DOT service animal air transportation form. United Airlines accepts this federal form — the same across airlines — which confirms your service animals are trained service animals, healthy per vaccination records, and able to behave. Emotional support animals are no longer recognized for the cabin; an emotional support animal and cats travel under United’s pet restrictions, not as a psychiatric service animal.
What is the United service animal form?
It is the DOT service animals attestation. The department of transportation standardized it, so United’s customers traveling with a service dog file the same document as on other airlines. Two following forms may apply: the transportation form, and a relief form for longer flights of 8+ hours. A veterinary health form is not the DOT form, though keeping health and vaccination records helps.
How to fill and submit the forms
Prepare before your upcoming travel: contact United’s accessibility department, request the additional documentation only if United says require additional documentation applies, and fill in the details. Confirming the form is on file before boarding avoids a pass problem at the seat. Submit at least 48 hours ahead; for a December or holiday trip, file earlier. These tips keep the process smooth.
What the form attests
- Your dog is a trained service animals handler’s dog that will assist with tasks.
- Health, including rabies — keep vaccination records ready even though United asks for an attestation, not a veterinary health form documenting every visit.
- The dog will sit on the floor at your seat, not an aisle, and will not anger or disturb other travelers or owners.
- A note: a psychiatric service animal uses the same form — no extra scrutiny.
ESAs, pets, and cabin vs cargo
Since the 2021 rule, an emotional support animal is not recognized as a service animal and flies as a pet — small cats or dogs in a carrier under the seat, never in cargo as a service animal. An ESA letter helps with housing, not flying. Only a dog can be a service animal for air travel.
At the airport
Bring a copy of the completed form. A vest or ID card is optional — federal law requires none. Your trained service animals ride free; there is no pet fee for an accepted service dog.
