Emotional Support Peacock Not Allowed On Flight

I have an Emotional Support Animal - my Cavalier King Charles Spaniel, Emma.  I obviously get the need to have the comfort of your animal in life, especially when travelling. That said, a PEACOCK?!? C'mon!

One of the rules of flying with your ESA is they must be able to fit in your lap or under the seat in front of you. This peacock's tail needs 3 seats just for the tail not to mention, aren't peacocks aggressive?
