Can my ESA Be a Psychiatric Trained Service Dog for Flying?

Yes, with proper training your ESA can become a Trained Service animal allowing your animal to travel in cabin free of charge. There are no certification requirements. Airlines cannot deny your service animal based on breed but they are allowed to restrict service animals to Dogs and deny boarding based on behavior.
Airlines recognize only Dogs as Service Animals.
