United Airlines Service Animal Policy Overview
Does United Airlines Accept Psychiatric Service Dogs?
Documentation Required for Service Dogs on United Airlines
To travel with a psychiatric service dog, United Airlines requires passengers to submit the following forms:
- Department of Transportation (DOT) Service Animal Air Transportation Form
- Service Animal Relief Attestation Form (for flights over 8 hours)
- Psychiatric Service Dog (PSD) Letter from a licensed mental health professional, confirming the need for a PSD.
You can complete and submit these forms through your MileagePlus account or bring them for verification at the airport.
What Is a PSD Letter, and How Can You Get One?
To obtain a PSD letter, you’ll first need to consult a qualified healthcare professional who can assess your situation and determine if a service animal would benefit you. If your condition warrants a service dog, the professional will issue a PSD letter.
Fast ESA Letter offers a straightforward way to obtain a PSD letter through online consultations with licensed mental health professionals. They provide convenient, legally compliant PSD letters that meet federal regulations, ensuring you have the documentation you need to travel with your psychiatric service dog on United Airlines.
How Can I Fly With My Psychiatric Service Dog On United Airlines?
You have two options for adding a service animal to your travel with United Airlines:
- When booking your ticket, check the service animal option when entering your traveler information.
- After booking your ticket, select the option to add a service animal when viewing your trip.
You need to call the Airlines for
- International flights
- Hawaii flights
- Guam flights
Why Is a PSD Letter Important During Your Travel?
A PSD letter from a licensed mental health professional also gives you added confidence and peace of mind throughout your journey. While the required DOT forms confirm your service dog’s eligibility for air travel, a PSD letter serves as additional verification of your need for the animal.
CDC Regulations for High-Risk Rabies Countries
- Be at least 6 months old
- Have an ISO-compatible microchip implanted before rabies vaccination
- Have a completed CDC Dog Import Form receipt that matches the arrival airport listed for entry into the U.S.
- Present a valid Certification of U.S.-Issued Rabies Vaccination form endorsed by the USDA before departure if previously vaccinated in the U.S.
If the service dog received its rabies vaccination outside the U.S., it must enter through an approved airport with a CDC-registered Animal Care Facility and may require a pre-booked reservation for inspection or quarantine procedures.
Because international animal import rules can change, travelers should review the latest CDC requirements and United Airlines guidelines before departure.
United Airlines Emotional Support Animal Policy
United Airlines Pet Travel Fees
Because United Airlines no longer recognizes emotional support animals (ESAs) as service animals, ESAs must travel under the airline’s standard pet policy and follow all applicable pet travel rules.
- Fee: $150 each way, plus an additional $125 fee for domestic layovers longer than 4 hours
- Eligible Species: Limited to domesticated dogs and cats only
- Cabin Requirement: Pets must remain fully inside an airline-approved hard-sided or soft-sided carrier that fits underneath the seat in front of you throughout the flight
Passengers traveling with ESAs should also review United Airlines’ carrier size requirements, pet capacity limits, and route restrictions before booking, as availability for in-cabin pets may be limited.
Do I Need To Provide United Airlines Health Certificate For Pets?
When flying abroad, you have to present rabies and health certifications in accordance with United Airlines’ pet policy. The vaccines against rabies must be finished at least 28 days prior to travel to the United States.
You need to have a pet health certificate with the following details if you’re going inside the United States:
- Name, phone number, and address.
- Specifics about your animal companion, like breed, color, age, sex, and patterns.
- Names, dates of issuance, and expiration dates of recent vaccines are mentioned.
Pet carrier requirements on United Airlines
- Hard-sided carriers: Length 17.5” x Width 12” x Height 9” (44 cm x 30 cm x 22 cm).
- Soft-sided carriers: Length 18” x Width 11” x Height 11” (45 cm x 27 cm x 27 cm).
Your pet must remain inside the carrier, secured under the seat in front of you.
