Airline Pet Policies in 2026

Current airline pet policies classify Emotional Support Animals as pets rather than service animals. Whether you're flying with American Airlines, Delta, United, Southwest, JetBlue, Alaska Airlines, Spirit, Frontier, or Allegiant, your ESA must usually travel under each airline's pet program. That typically means paying a pet fee, using an airline-approved carrier that fits beneath the seat, and reserving your pet's space before departure because airlines limit the number of pets allowed in the cabin.

Although an ESA Letter no longer provides free air travel, it remains the legal documentation that protects your housing rights under the Fair Housing Act, allowing many renters to live with their emotional support animal in no-pet housing without pet fees.

Unlike Emotional Support Animals, Psychiatric Service Dogs (PSDs) continue to qualify as service animals under the Air Carrier Access Act (ACAA). A properly trained Psychiatric Service Dog may travel in the aircraft cabin without additional pet fees and does not need to remain inside a carrier during the flight.

Most airlines require passengers traveling with a PSD to complete the official DOT Service Animal Air Transportation Form before departure. If your disability requires a task-trained service dog, obtaining a legitimate PSD Letter and completing the necessary documentation provides the strongest support for housing, workplace accommodations, and airline travel.

Many websites continue advertising airline ESA certificates, ESA registrations, or ESA IDs that claim to restore free airline travel. These products have no legal value under current DOT regulations. No certificate, registration, or identification card can allow an Emotional Support Animal to fly as a service animal.

Travelers should also avoid falsely representing a pet as a Psychiatric Service Dog, as many airlines and states have strengthened penalties for service animal misrepresentation. The safest approach is to travel honestly, reserve your pet in advance, and understand your airline's current pet travel policy before booking your flight.

Major legacy carriers

American Airlines, Delta Air Lines, United Airlines

Most major airlines allow Emotional Support Animals to travel through their in-cabin pet programs. Pet fees commonly range from $95–$150 each way, depending on the airline and route. Your pet must remain inside an approved carrier beneath the seat during the flight, while Psychiatric Service Dogs travel free when accompanied by the required DOT documentation.

Low-cost carriers

Southwest Airlines, JetBlue Airways, Alaska Airlines

These airlines also classify ESAs as pets and generally charge pet travel fees between $95 and $125. Space for pets is limited on every flight, making early reservations highly recommended. Task-trained Psychiatric Service Dogs continue receiving free cabin access under federal DOT rules.

Ultra-low-cost carriers

Spirit Airlines, Frontier Airlines, Allegiant Air

Ultra-low-cost airlines generally maintain stricter size, weight, and carrier requirements for pets. International travel options may also be more limited. However, Psychiatric Service Dogs remain protected under the Air Carrier Access Act, allowing qualified handlers to travel without standard pet fees.

International routes

All airlines

International travel requires much more planning than domestic flights. Depending on your destination, you may need health certificates, vaccination records, ISO microchips, import permits, or quarantine documentation. Hawaii also maintains unique animal entry requirements despite being a domestic destination. Whenever possible, begin planning your international trip 60 days or more before departure.

Airline pet policies and travel fees frequently change, always review your airline's latest pet travel guidelines before booking. For a complete explanation of the current regulations, read our guide on Do ESAs Fly Free in 2026?

Although Emotional Support Animals no longer receive free airline travel, a legitimate ESA Letter continues to provide valuable housing protections under the Fair Housing Act. If you're seeking accommodation in pet-restricted housing, start with a clinical evaluation from a licensed mental health professional and receive documentation that landlords can verify with confidence.
