By keeping these tips in mind, you’re setting the stage for a smooth and enjoyable travel experience with your favorite companion.

United Airlines Pet Travel Rules

Traveling with your furry friend on United Airlines? Here’s what you need to know:

If you’re bringing a pet, it must travel in either a hard-sided or soft-sided carrier that fits under the seat in front of you. Service animals are the only exception, and they can travel without a carrier.

While pets have no weight or breed restrictions, they must adhere to specific carrier dimensions.

  • Hard-sided carriers must have a height of 9 inches, a length of 17.5 inches, and a width of 12 inches.
  • Soft-sided carriers should have a height of 11 inches, length of 18 inches, and width of 11 inches.

United Airlines doesn’t allow pets in cargo except under rare circumstances, such as for active duty U.S. military personnel on permanent change of station orders traveling between Honolulu and Guam or for Foreign Service Personnel on current reassignment.

The PetSafe program, which allowed pets to travel as cargo, has been suspended since 2018.

TL;DR: Pets must travel in carriers that fit under the seat. No cargo travel except for specific military or foreign service circumstances. The PetSafe program has been suspended since 2018.

United Airlines Fees for Pet Travels

If you purchased your ticket before April 26, 2024, there’s a fee of $125 each way for bringing your pet along. This means your pet can ride with you, making your journey together smoother.

However, if you have a layover that extends more than four hours on domestic flights or 24 hours on international flights, there’s an extra $125 fee per stop.

Unfortunately, travel credits can’t cover these specific fees. Keeping that in mind, you’ll want to plan your payment.

For those booking their tickets on or after April 26, 2024, the fee for pet travel is $150 each way. This updated fee structure reflects the ongoing commitment to providing a comfortable and safe journey for both you and your pet.

Reviewing your travel itinerary and budget for these costs is always a good idea. It ensures a hassle-free experience when flying with your beloved companion.

Remember: Traveling with pets might come with extra costs. But the joy of having them by your side is worth every penny!

United Airlines and the ACAA

Under the framework of the Air Carrier Access Act (ACAA), United Airlines ensures compliance by accommodating passengers with disabilities. It includes those who rely on emotional support animals (ESAs) and a service animal like a service dog. 

The airline strictly adheres to guidelines that prevent discrimination based on disabilities. It allows for the inclusion of service dogs on flights.

  • Crate Comfort: If your ESA needs to be in a crate, ensure it’s comfortable and familiar with the crate before the journey. This can help reduce stress.
  • Direct Flights: Whenever possible, book direct flights to minimize the stress on your animal and reduce the complexity of managing multiple flights.

By following these tips, you and your ESA or service animal can have a smoother and more enjoyable travel experience with United Airlines.

Required Forms and Documents for ESAs

When traveling with Emotional Support Animals (ESAs) or Psychiatric Service Dogs (PSDs) on United Airlines, passengers are required to provide specific documentation to ensure compliance with airline policies and federal regulations.

ESA Letter or PSD Letter

Traveling with an ESA or PSD on United Airlines can significantly impact fees, permits, and restrictions, primarily by providing an ESA or PSD Letter. 

An ESA Letter issued by a licensed mental health professional states the need for an emotional support animal to help mitigate the owner’s psychological or emotional disability. This letter exempts the owner from pet fees and allows the animal to travel in the cabin without extra charges. 

In contrast, a PSD Letter pertains specifically to service dogs trained to perform tasks for individuals with psychiatric disabilities. The rights afforded by a PSD are broader under the Americans with Disabilities Act, allowing these animals in more public areas and not just in airline cabins or housing. 

Obtaining either letter requires certification from a healthcare provider attesting to the individual’s need for the animal due to their disability.

Behavior Form

United Airlines requires a Behavior Form to ensure that ESAs and PSDs are well-behaved and can safely interact with the public and other animals. This form typically confirms that the animal has not displayed aggressive behaviors and can remain under control in a busy environment such as an airport or airplane. 

ESA Pet offers to assist in acquiring this form as part of their ESA Letter service packages. The Behavior Form is crucial as it helps the airline maintain safety and comfort for all passengers.

Health Form

A Health Form is also mandatory for ESAs and PSDs flying on United Airlines. This form generally includes details about the animal’s recent vaccinations, overall health status, and fitness to travel. A veterinarian must sign the form, indicating that the animal is free from diseases that could pose a risk to others.

ESA Pet assists in obtaining these health forms during the ESA Letter acquisition process, ensuring that all paperwork is complete and up to date before travel.

Getting an Official ESA Letter and Additional Documentation

The process to acquire an ESA letter through ESA Pet is designed to be straightforward and consists of three main steps:

Step 1: Initial Quick Assessment

You’ll begin by completing a quick online questionnaire offered by ESA Pet. This survey contains several important questions regarding your mental health, which you can fill out confidentially. This step aims to gather initial information to assist the evaluating mental health professionals in understanding your situation better.

Step 2: Consultation with a Mental Health Professional

Once you complete the initial assessment and your payment is processed, ESA Pet will arrange a consultation with a licensed mental health professional in your state. This expert will conduct a more detailed evaluation of your mental and emotional condition to ascertain whether an emotional support animal could benefit you.

Step 3: Receiving Your ESA Letter

If the mental health professional determines that an ESA could aid your treatment, they will issue an ESA letter for you. This letter, which confirms the need for your emotional support animal, will be sent to you digitally by ESA Pet within three business days of the approval.

Prepping the ESA to Fly

When planning to travel with an Emotional Support Animal (ESA), preparing adequately is essential to ensure a smooth and stress-free journey for you and your pet. Here are some best practices:

  1. Training: Ensure your ESA is well-trained to handle public settings and large crowds, which you’ll likely encounter at the airport and on the plane.
  2. Health Check: Visit your vet for a check-up before traveling to ensure your ESA is healthy and fit for travel. Make sure all vaccinations are up to date.
  3. Familiarization with the Pet Carrier: If your ESA isn’t used to a pet carrier, familiarize them with it to reduce anxiety during the flight.
  4. Exercise Before the Flight: A well-exercised animal is typically calmer. Try to let your ESA have some exercise before heading to the airport.
  5. Comfort Items: Bring items familiar to your ESA, like a favorite blanket or toy, to help soothe and comfort them during the flight.
  6. Hydration and Feeding: Feed your ESA a light meal a few hours before the flight, and bring a collapsible water dish to keep them hydrated.
