The Air Carrier Access Act (ACAA) has changed how emotional support animals are handled during air travel. If you rely on an ESA for mental health support, it’s important to understand what airlines allow today—before you book a flight.
In simple terms, ESAs are no longer treated like service animals for flights under current U.S. Department of Transportation rules. Most airlines now allow emotional support animals only under their pet travel policies, which usually means carrier requirements, size limits, and added fees.
This guide explains the current ACAA emotional support animal rules, what changed in 2021, and what you can realistically expect when flying with an ESA.
The Air Carrier Access Act (ACAA) was passed in 1986 to protect passengers with disabilities from discrimination during air travel. It applies to flights operated by U.S. airlines and to foreign airlines flying to, from, or within the United States.
The purpose of the ACAA is to ensure equal access in air transportation. It covers important protections such as boarding assistance, seating accommodations, and the right to travel with necessary disability-related support.
For many years, the ACAA also allowed travelers to bring both service animals and emotional support animals on flights, often with fewer restrictions than today.
In December 2020, the U.S. Department of Transportation (DOT) issued a final rule that significantly revised the ACAA's animal accommodation provisions. This revision, which took effect in January 2021, fundamentally altered how airlines handle emotional support animals.
The key change narrowed the definition of "service animal" under the ACAA to align more closely with the Americans with Disabilities Act (ADA) definition. Under this revised framework, a service animal is specifically defined as a dog that is individually trained to do work or perform tasks for the benefit of a person with a disability, including physical, sensory, psychiatric, intellectual, or other mental disabilities.
The 2021 ACAA revisions fundamentally restructured how airlines handle emotional support animals, creating a new landscape that travelers must navigate.
What Airlines Are Required to Do
Under current ACAA regulations, airlines have no obligation to accommodate emotional support animals as anything other than pets. The DOT's revised rule explicitly states that airlines may treat emotional support animals according to their standard pet policies rather than as service animals.
Airlines must still:
What Airlines Are No Longer Required to Do
Airlines are no longer required to:
Each airline has developed its own approach to emotional support animals following the regulatory changes. While most major U.S. carriers adopted similar policies aligned with the new ACAA framework, subtle differences exist:
Major carriers like American Airlines, Delta Airlines, United Airlines, and Southwest Airlines typically treat all ESAs as pets, requiring them to meet standard pet travel criteria including fitting in an approved carrier that slides under the seat, meeting weight limits (usually 20 pounds or less), and paying applicable pet fees.
Budget carriers like Spirit Airlines, Frontier Airlines, and Allegiant Air often have more restrictive pet policies with limited availability, making travel with an ESA more challenging and potentially requiring planning and early booking.
Regional and international carriers including Alaska Airlines, JetBlue, and Air Canada have also updated their policies to align with current ACAA standards.
Before 2021, many airlines allowed emotional support animals to fly in the cabin if passengers provided an emotional support animal letter from a licensed mental health professional. In most cases, travelers also needed basic confirmation that the ESA was necessary for mental health support during the flight.
However, these ESA documents no longer carry weight under current ACAA rules. Airlines may still allow ESAs, but only under their standard pet policies, meaning carriers, fees, and size limits apply.
For trained psychiatric service dogs, airlines may now require stricter paperwork, including DOT service animal forms confirming the dog’s disability-related role, trained tasks, behavior standards, and health/vaccination records.
If your dog performs task-based support, you may want to explore getting a psychiatric service dog letter to support proper classification and travel documentation.
Despite regulatory changes, many individuals still wish to travel with their emotional support animals. Understanding your options helps you make informed decisions.
When planning air travel with an ESA, consider these approaches:
Pet accommodation: Most airlines allow small pets in cabin carriers for fees ranging from $95-$200 per flight segment. Your ESA must fit comfortably in an approved carrier that slides under the seat, typically restricting animals to 20 pounds or less. The logistics of flying with a dog as a pet differ significantly from the previous ESA accommodations, requiring careful planning and preparation.
Psychiatric service animal pathway: If your animal performs trained tasks that mitigate your psychiatric disability, you may qualify to travel with a psychiatric service animal. This requires documentation of specific trained tasks and may involve working with a professional trainer to develop and document these skills.
The distinction between psychiatric service dogs and ESAs is crucial, only animals with specialized task training qualify for service animal accommodations.
Alternative travel methods: For some routes, driving, train travel, or bus transportation may accommodate your ESA more easily and cost-effectively than air travel. For example, Amtrak allows dogs on many routes with fewer restrictions than airlines, making train travel a viable alternative for shorter distances.
Leaving your ESA at home: Depending on trip duration and the availability of support at your destination, traveling without your ESA while arranging alternative coping strategies may be the most practical option.
If you choose to bring your ESA as a pet, thorough preparation ensures a smoother experience:
Carrier training: Acclimate your animal to their travel carrier weeks before your trip. Practice having them remain calm inside the carrier for extended periods. Investing in appropriate dog crates and carriers designed for air travel makes a significant difference in your animal's comfort and safety.
Behavioral preparation: Ensure your ESA can remain quiet and calm in stressful environments with crowds, loud noises, and unfamiliar smells. Proper emotional support dog training prepares your animal for the unique challenges of airport and cabin environments, reducing stress for both you and your pet.
Health considerations: Verify that your ESA is healthy enough for air travel. Some animals experience significant stress during flights, which may outweigh the benefits of having them present. Airlines typically require current vaccinations, and ensuring your pet has received necessary immunizations like the Bordetella vaccine prevents travel delays and protects other animals.
Airline-specific requirements: Review your airline's pet policy carefully, noting carrier specifications, weight limits, breed restrictions, and documentation requirements.
Booking logistics: Reserve pet space when booking your ticket, as airlines limit the number of pets per flight. Confirm your reservation includes pet accommodation 24-48 hours before departure.
Costs to Anticipate
Traveling with an ESA as a pet involves several expenses that go beyond the typical costs associated with emotional support animals in housing situations:
A roundtrip flight with an ESA can easily cost $300-$500+ beyond standard ticket prices, making it essential to budget appropriately. When comparing pet insurance, pet deposits, and ESA letter investments, it becomes clear that ESA documentation provides the most value for housing accommodations rather than air travel under current regulations.
For some travelers, the costs and logistics of flying with an ESA outweigh the benefits. Consider these alternatives:
Professional pet sitting: Leaving your ESA with a trusted pet sitter or boarding facility may reduce travel stress for both you and your animal.
Temporary support strategies: Work with your mental health provider to develop coping mechanisms for your trip duration, potentially including medication adjustments or therapeutic techniques.
Destination-based support: Arrange for temporary ESA services at your destination through local resources or organizations.
Shorter trips: Limiting travel duration reduces time away from your ESA.
ESA rules may continue to evolve, particularly in areas such as documentation standards and fraud prevention. While the ACAA no longer requires airlines to accommodate emotional support animals, ongoing policy discussions could still influence how ESAs are verified and treated across travel and housing contexts.
What may change next:
Why it matters for air travel:
Some disability advocates support the ACAA changes because they reduce misuse and protect service-dog access. Others worry the shift makes travel harder for people with psychiatric disabilities who rely on ESAs but don’t have task-trained service dogs.
For now, the safest approach is to assume airline policies will remain strict and to check requirements before every trip.
While the ACAA no longer mandates airline accommodation of emotional support animals, other federal protections remain intact, creating a complex legal framework for ESA handlers.
Fair Housing Act Protections
Even though the ACAA no longer requires airlines to accommodate ESAs, the Fair Housing Act (FHA) still protects them in housing. Landlords must make reasonable accommodations for ESAs, even in no-pet properties, and they can’t charge pet deposits or monthly pet rent. To qualify, you’ll need documentation from a licensed healthcare provider confirming your disability-related need.
State and Local Regulations
Many states follow federal ESA standards but may add extra rules, especially around fraud prevention and misrepresentation penalties. Because laws vary, it’s important to review ESA regulations in your specific state before requesting accommodations.
Workplace Accommodations
In some cases, ESAs may be requested at work under the ADA, but approval is not automatic. Employers can deny ESA requests if they create safety issues, disrupt operations, or cause undue hardship.
Educational Institution Policies
Many colleges allow ESAs in student housing through disability services, but they are usually not allowed in classrooms or dining halls. Students typically need proper documentation and must follow campus-specific ESA guidelines.
Misunderstandings about emotional support animal regulations create confusion and unrealistic expectations.
No legitimate ESA registry or certification exists. Websites selling ESA registration certificates, ID cards, or vests provide no legal protection or official status. These items are marketing gimmicks that prey on misunderstanding of ESA regulations.
The only documentation that matters for legal ESA accommodations is a letter from a licensed mental health professional establishing your disability-related need. Registration services and certificates hold no legal weight and may actually undermine your credibility by suggesting unfamiliarity with legitimate accommodation processes.
Similarly, emotional support dog certification programs have no legal standing under federal law.
Emotional support animals do not have public access rights. Unlike service animals, which may accompany their handlers in most public spaces, ESAs are protected only in housing situations under the Fair Housing Act and specific other limited contexts.
Businesses, restaurants, stores, hotels, transportation services, and other public accommodations are not required to allow emotional support animals. Some businesses may permit well-behaved animals at their discretion, but this reflects their policies rather than legal obligations.
For instance, most retail stores and restaurants do not allow ESAs, and major retailers like Walmart have specific ESA policies that restrict access to trained service animals only.
As thoroughly discussed, current ACAA regulations do not require airlines to accommodate emotional support animals beyond their standard pet policies. ESA letters that were once sufficient for cabin access now hold no significance for airline accommodation requirements.
Presenting an ESA letter at the airport will not grant cabin access for an animal that doesn't meet the airline's pet policy. This misconception causes significant problems for travelers who arrive expecting accommodation based on outdated information.
In fact, some poorly behaved animals have been placed on airline no-fly lists, emphasizing the importance of understanding current regulations before attempting to travel.
While some legitimate telehealth services provide quality mental health care, many online ESA letter services lack clinical legitimacy. These services often provide generic letters after minimal evaluation, creating documentation that may not withstand scrutiny from housing providers or legal challenges.
Legitimate mental health care involves comprehensive evaluation, therapeutic relationship development, and ongoing treatment. Quality cannot be replaced by 10-minute questionnaires and automated letter generation.
The question of whether online ESA letters are legitimate depends entirely on whether the service connects you with properly licensed professionals who conduct thorough evaluations and establish genuine therapeutic relationships.
While emotional support animals aren't required to have specialized task training like service animals, responsible ESA ownership includes basic training and socialization. An ESA should respond to basic commands, behave appropriately in various settings, and not pose disturbances to others.
Untrained, poorly socialized ESAs create problems for neighbors in housing situations, damage the credibility of legitimate ESA needs, and may result in loss of accommodation privileges. Investing in basic obedience training benefits both you and your animal.
If you're wondering how to make your dog an ESA, the process involves both obtaining proper documentation and ensuring your animal is well-behaved and socialized.
In conclusion, navigating ACAA emotional support animal regulations in 2026 requires understanding that air travel accommodations have fundamentally changed while housing protections remain strong.
Although airlines no longer must accommodate ESAs as service animals under current regulations, the Fair Housing Act continues to provide robust protections for individuals who rely on ESAs for mental health stability.
The key to successfully advocating for your ESA rights lies in obtaining legitimate documentation from licensed mental health professionals, understanding the distinction between ESAs and psychiatric service animals, and knowing which protections apply in different contexts.
As regulations continue evolving, staying informed about your rights and responsibilities as an ESA owner ensures you can access appropriate accommodations while maintaining the credibility of legitimate emotional support animal needs.
As ESA rules continue to evolve, it’s important to stay informed about your rights and responsibilities. This helps you access the right accommodations and protects the credibility of legitimate ESA needs.
