The image, snapped on board an American plane, shows a miniature horse in what appears to be an economy cabin on a flight.

The horse’s face is concealed mostly by a blue mask with a star print.

According to the image caption, the pony is a “service animal.”

The caption reads: “THIS IS A LEGITIMATE, HIGHLY-TRAINED SERVICE ANIMAL USED FOR THE BLIND, ETC., it is NOT an Emotional Support Animal."
