The service pet doesn't have be in a cage in the hold or under the seat per the usual rules. It is abuse of an ADA law with unintended consequences.

People need to pay for these uncertified emotional support animals the same as airlines have always done for pets. If it is too big to go under the seat, then buy it a ticket. Even if the animal doesn't sit in the seat, it has the floor space to lie down, instead of crowding somebody else's foot space.
