Frontier Airlines knew that the woman, who was bound for Cleveland, Ohio, would be travelling with an emotional support animal, but they claim they were unaware that it would be a squirrel.

Squirrels, which are not allowed in Frontier Airlines's guidelines, are considered dangerous as they can be quite aggressive, and would put other passengers on the flight in an uncomfortable situation.
