ESA Flight Letter + Assessment.

An ESA travel letter written and signed by a licensed mental health professional after a short online assessment. Please read before you buy: since the 2021 U.S. Department of Transportation rule, U.S. airlines may treat emotional support animals as pets, so pet fees and carrier rules apply on U.S. flights. A few airlines outside the U.S., mainly in Latin America, still accept ESAs on some routes. Policies change often, so confirm with your airline first. If your dog is trained to perform tasks for a psychiatric disability, U.S. airlines accept psychiatric service dogs with the DOT service animal forms.
