The Ultimate Guide to Navigating Airline Pet Policies for Emotional Support Animals in 2026

The 2026 DOT Airline Rules for Support Animals

Flying with a pet can be incredibly stressful and expensive, with airlines charging upwards of $125 each way just to keep your pet stuffed under a seat. However, the Department of Transportation (DOT) has updated its guidelines regarding assistance animals.

While standard Emotional Support Animals (ESAs) are no longer guaranteed free flights, Psychiatric Service Dogs (PSDs) are federally protected. A PSD can fly in the cabin with you completely free of charge, and they are not required to stay in a carrier.

How to Qualify for a PSD Letter

To fly with your dog as a Psychiatric Service Dog, you need two things: a dog that is trained to perform a specific task to aid with a mental health disability (like deep pressure therapy for panic attacks), and a legal letter from a licensed mental health professional.

At PetCerts, our licensed therapists specialize in evaluating passengers for PSD travel letters. We ensure your documentation meets all airline requirements so you can travel without harassment or illegal fees.
