✈ Department of Transportation (DOT) Revised Its Rules: What ESA and Service Animal Owners Need to Know

 

The Department of Transportation (DOT) revised its rules in January 2021, creating a major shift in how airlines handle emotional support animals (ESAs) and service animals. For years, ESA owners could fly with their animals in the cabin without paying extra fees, provided they had proper documentation. However, the revised rules changed that landscape entirely — redefining who qualifies as a service animal and how ESAs are treated under federal travel law.

In this article, we’ll break down what the DOT’s revisions mean, how they impact ESA and psychiatric service dog (PSD) owners, and what steps you can take to travel smoothly in 2025 and beyond.

Why Did the DOT Revise Its Rules?

The DOT updated its Air Carrier Access Act (ACAA) regulations after years of complaints from airlines, passengers, and disability advocates. Some passengers were abusing ESA policies, bringing untrained animals — from peacocks to miniature horses — on planes, creating safety and health concerns. Airlines pushed for clearer guidelines, while disability advocates sought to ensure that legitimate service animal users weren’t unfairly impacted.

The final decision struck a balance: ESAs would no longer be recognized as service animals under federal law, while psychiatric service dogs (PSDs) retained full protections.

Key Changes in the DOT’s Revised Rules

  1. Service Animal Definition Narrowed

    • Only dogs trained to perform tasks for a person with a disability now qualify as service animals.

    • Emotional support animals no longer count as service animals under the ACAA.

  2. Airline Recognition of ESAs Ended

    • Airlines are no longer required to treat ESAs as service animals.

    • ESAs are now considered pets, subject to carrier fees, size restrictions, and airline-specific policies.

  3. Documentation Requirements

    • Passengers traveling with psychiatric service dogs must provide DOT service animal forms attesting to the dog’s training and health.

    • ESAs no longer need letters for airline travel since they’re treated as pets, though documentation may still help in housing contexts.

  4. Airline Discretion

    • Airlines may still choose to allow ESAs in cabins, but they are not obligated to do so.

    • Policies vary widely — some carriers remain ESA-friendly, while others enforce stricter rules.

How the DOT Rule Impacts ESA Owners

For ESA owners, the biggest impact is airline travel costs and logistics. Before 2021, an ESA letter allowed you to bring your animal into the cabin free of charge. Now:

  • You’ll need to pay pet fees, often ranging from $95–$200 per flight.

  • Your ESA must meet airline pet policies (carrier size, weight limits, etc.).

  • Larger ESAs may need to travel in cargo, which can be stressful for both owner and animal.

However, the DOT’s revised rules don’t affect ESA protections in housing. Under the Fair Housing Act (FHA), landlords must still make reasonable accommodations for tenants with valid ESA letters.

How the DOT Rule Impacts Psychiatric Service Dog Owners

For PSD owners, the revisions actually reinforced protections:

  • PSDs are recognized as service animals under the new rules.

  • Airlines must allow PSDs to fly in-cabin at no extra charge.

  • Owners must complete DOT forms confirming their dog is trained to perform disability-related tasks.

This distinction highlights the importance of understanding whether your animal qualifies as an ESA or a PSD.

What Travelers Can Do in 2025

If you’re planning air travel with your support animal, here are some practical steps:

  1. Check Your Status

    • If your animal is a trained psychiatric service dog, you’re protected under DOT rules.

    • If your animal is an ESA, prepare to follow pet travel policies.

  2. Know Your Airline’s Rules

    • Review each airline’s ESA and pet policy before booking. Some carriers may still allow ESAs in the cabin.

  3. Budget for Pet Fees

    • Factor in additional costs for ESA travel, especially for frequent flyers.

  4. Consider PSD Training

    • If your ESA provides disability-related tasks and you pursue PSD training, your dog may qualify for full protections.

  5. Secure Housing Rights Separately

    • Remember that the DOT’s rules only affect air travel. Your ESA letter still protects you under the Fair Housing Act.

Conclusion

The Department of Transportation (DOT) revised its rules to tighten regulations on emotional support animals, removing their special status on flights while reaffirming protections for psychiatric service dogs. While this has added costs and challenges for ESA owners, understanding the distinctions and preparing in advance can make travel far less stressful.

In 2025, the best strategy is to stay informed, use legitimate ESA or PSD documentation, and plan ahead for both housing and travel. By doing so, you’ll navigate the new rules with confidence and ensure that your support animal remains a vital part of your journey.
