Thank you, remoandiris, for the work you put in to help me on this issue. In practice i go by the general definition of my ESA as a pet except for the very limited coverage allowed by the FHA and FAA. There's room for improvement in laws and policies regarding ESAs however. For instance, i find it absurd that an ESA is not allowed the same privileges on railroads in the United States as they do on airlines. I can't imagine taking Matilda with me on a flight but would sure like to travel with her on a train.
