ESA Travel Rules 2026: What Changed & Why

If you rely on an emotional support animal for mental health, navigating air travel has become significantly more complicated in recent years. What was once a straightforward process, present an ESA letter and fly with your animal in the cabin for free, has been transformed by regulatory changes that reclassified how airlines must treat emotional support animals. The confusion is understandable. Regulations have shifted, airline policies vary, and misinformation abounds online. Some websites still claim you can fly with any ESA for free, while others suggest the concept of emotional support animals has been eliminated entirely. The truth, as usual, lies somewhere in between.

This guide cuts through the noise to give you a clear, accurate picture of emotional support animal travel rules as they stand in 2026, including your rights, your options, and how to plan travel with your support animal.

The Regulatory Shift: What Changed and Why

The Old Rules (Pre-2021)

Under the original Air Carrier Access Act (ACAA), airlines were required to allow emotional support animals to fly in the cabin free of charge, provided the passenger had a letter from a licensed mental health professional. This led to a surge in ESA registrations and, controversially, to incidents involving unusual animals (peacocks, pigs, miniature horses) on flights. Airlines argued that the system was being abused, with passengers fraudulently claiming pet status to avoid pet fees. The number of ESA animals on flights increased by over 200 percent between 2016 and 2019, straining airline resources and creating safety concerns.

The DOT Rule Change (January 2021)

In January 2021, the U.S. Department of Transportation published a final rule that fundamentally changed the landscape:

• Only trained psychiatric service dogs are recognized as service animals under the ACAA.
• Airlines are no longer required to treat emotional support animals as service animals.
• Airlines may treat ESAs as pets, subject to standard pet policies including fees, size restrictions, and carrier requirements.
• The rule defines a service animal as “a dog that is individually trained to do work or perform tasks for the benefit of a person with a disability.”

The Impact

This means that emotional support animals, whether dogs, cats, rabbits, or any other species, no longer have guaranteed free access to airplane cabins. Airlines may (and most do) require ESA owners to follow standard pet travel policies.

Current Airline Policies for ESAs in 2026

Each airline sets its own policy regarding emotional support animals. Here is how the major carriers handle ESAs as of 2026:

Airlines That Treat ESAs as Regular Pets

Airline	In-Cabin Pet Fee	Size Limit	Carrier Required
American Airlines	$150 each way	Must fit under seat	Yes
Delta Air Lines	$150 each way (domestic)	Must fit under seat	Yes
United Airlines	$150 each way	Must fit under seat	Yes
Southwest Airlines	No pet fee (ESAs not accommodated; pets not accepted either)	N/A	N/A
JetBlue	$125 each way	Must fit under seat	Yes
Alaska Airlines	$100 each way	Must fit under seat	Yes
Spirit Airlines	$125 each way	Must fit under seat	Yes
Frontier Airlines	$99 each way	Must fit under seat	Yes

Important note about Southwest: Southwest Airlines does not accept pets in the cabin at all. Only trained psychiatric service dogs are allowed to fly, accommodated free of charge with proper documentation.

What This Means Practically

If your emotional support animal is a small dog or cat (under approximately 20 pounds including carrier):

• You can fly with them as a regular pet
• You will pay a pet fee ($75 to $150 each way)
• They must fit in an airline-approved carrier under the seat
• You must book their spot in advance (limited spaces per flight)

If your emotional support animal is larger than what fits under the seat:

• Most airlines will not allow them in the cabin
• Cargo transport is an option for some airlines but involves significant additional cost and stress
• You may need to explore alternative travel arrangements

Psychiatric Service Dogs vs. Emotional Support Animals

Understanding the legal distinction between psychiatric service dogs (PSDs) and emotional support animals (ESAs) is critical:

Psychiatric Service Dogs

A psychiatric service dog is a dog that has been individually trained to perform specific tasks directly related to a person’s psychiatric disability. Examples of trained tasks include:

• Interrupting self-harming behaviors
• Providing deep pressure therapy during panic attacks
• Alerting to oncoming anxiety or PTSD episodes
• Guiding a disoriented handler to safety
• Retrieving medication during a crisis

Air travel rights: PSDs fly in the cabin free of charge under the ACAA. Airlines may require the handler to complete DOT forms attesting to the dog’s training and behavior, but they cannot charge a fee or require the dog to be in a carrier.

Emotional Support Animals

An ESA provides comfort and emotional support through companionship. They do not require specific task training. Their presence alone provides therapeutic benefit, typically documented by a licensed mental health professional.

Air travel rights: ESAs have no special air travel rights under current federal law. They are treated as pets.

The Gray Area

If you currently have an ESA and believe you would benefit from a psychiatric service dog, discuss this with your mental health provider. Some ESAs may be candidates for specific task training that would qualify them as psychiatric service dogs. However, this requires genuine training, not simply relabeling.

Pet Parent Tip: Be wary of online services that offer to “certify” or “register” your pet as a service animal. According to the ADA, there is no official federal registry for service animals in the United States. Legitimate psychiatric service dog designation comes from genuine training and the handler’s documented disability, not a certificate purchased online.

Your Rights Under Current Law

While the landscape has changed, ESA owners still have important protections in certain contexts:

Housing

The Fair Housing Act (FHA) still recognizes emotional support animals and requires landlords to make reasonable accommodations for tenants with ESAs. This includes:

• Waiving no-pet policies
• Waiving pet deposits and pet rent
• Allowing animals that would otherwise be restricted by breed or size

You will need a letter from a licensed mental health professional documenting your need for the ESA. This right is unaffected by the DOT airline rule changes.

State Laws

Some states have additional protections for ESA owners that may extend to travel-related contexts:

• California has strong ESA protections in housing and is exploring expanded public access rights.
• New York requires certain businesses to accommodate ESAs.
• Colorado has passed laws to prevent ESA discrimination in housing.

However, no state law currently overrides the federal DOT rule regarding airline travel.

International Carriers

Some international airlines still accommodate ESAs with proper documentation:

• Volaris (Mexico): May accept ESAs with a letter from a licensed mental health professional.
• LATAM (South America): Has policies accommodating ESAs on some routes.
• Aeroméxico: May accept ESAs with proper documentation.

Always verify current policies directly with the airline before booking, as these policies change frequently.

Planning ESA-Friendly Travel

Flying

If you need to fly with your emotional support animal:

1. Check if your animal qualifies as an in-cabin pet based on size and carrier restrictions.
2. Book early. Airlines limit the number of in-cabin pets per flight. Spots fill up quickly.
3. Budget for pet fees. At $100 to $150 each way, pet fees add $200 to $300 per round trip.
4. Get a health certificate from your veterinarian within 10 days of travel.
5. Have your ESA letter available even though airlines are not required to honor it. Some gate agents may offer courtesy accommodations.
6. Choose direct flights to minimize stress for your animal.

Driving

Road trips are often the best option for ESA owners. You maintain complete control over the environment, there are no fees, and there are no size restrictions.

• Plan pet-friendly stops every two to three hours.
• Book pet-friendly hotels along your route (see our guide to pet-friendly hotel chains).
• Secure your animal in a crate, carrier, or crash-tested harness.
• Bring comfort items like familiar blankets, toys, and treats.

Train Travel

Amtrak allows small dogs and cats (combined weight with carrier under 20 pounds) on trips of seven hours or less for a $35 fee. ESAs receive no special accommodation on Amtrak.

Bus Travel

Greyhound and most intercity bus services do not allow pets other than service animals. ESAs are not accommodated.

Documentation You Should Carry

Even though airlines are not required to honor ESA letters, having proper documentation can help in various travel situations:

ESA Letter

A legitimate ESA letter should:

• Be written on the mental health professional’s letterhead
• Be signed by a licensed mental health professional (psychologist, psychiatrist, licensed clinical social worker, or licensed professional counselor)
• State that you have a diagnosed mental health condition listed in the DSM-5
• State that the animal provides necessary emotional support related to your condition
• Be dated within the last year
• Include the professional’s license number and contact information

Veterinary Records

• Current vaccination records (especially rabies)
• Health certificate (for air travel, issued within 10 days)
• Microchip information
• Any relevant medical records

Identification

• ID tags on your animal’s collar with your cell phone number
• Photos of your animal on your phone
• Microchip registration confirmation

Managing Travel Anxiety Without Your ESA

If you cannot bring your ESA on a trip, here are strategies for managing anxiety:

• Discuss travel-specific coping strategies with your therapist before the trip.
• Consider temporary medication adjustments with your prescribing provider.
• Practice grounding techniques (5-4-3-2-1 sensory exercise, box breathing, progressive muscle relaxation).
• Download calming apps like Calm, Headspace, or Insight Timer.
• Bring comfort items associated with your ESA (a blanket with their scent, photos).
• Arrange for a trusted pet sitter so you are not worrying about your animal’s care while traveling.
• Stay connected through pet cameras like Furbo that let you see and talk to your ESA remotely.

Looking Forward

The ESA travel landscape continues to evolve. Several developments may shape the coming years:

• Airlines may differentiate ESA policies as competitive strategy, with some carriers offering ESA-friendly programs to attract loyal customers.
• Technology solutions like telehealth ESA evaluations and digital documentation may streamline the process.
• Legislative efforts at both state and federal levels may restore some protections for ESA travel.
• Industry self-regulation through organizations like Airlines for America may establish more standardized ESA protocols.

For now, the best approach is to stay informed, plan ahead, and advocate for your needs within the current legal framework. Our guide to managing pet travel anxiety can help keep your companion calm during flights. Your emotional support animal provides genuine therapeutic benefit, and while the rules for air travel have changed, the value of that bond remains unchanged.

Travel may require more planning than it used to, but with the right preparation. Compare your options in our guide to every major airline’s pet policy, you and your emotional support animal can continue to explore the world together.
