Apart from guide dogs and helper dogs who can board airplanes with their human partners, Japanese airlines keep pets in a part of the cargo hold. Star Flyer, based in the Fukuoka Prefecture city of Kitakyushu, is looking to allow small dogs and cats which could fit in a carrier of around 50 centimeters long by 40 cm wide and 40 cm high to be carried into the passenger area. The owner would board while keeping their pet in the carrier. Although giving pets water will be allowed, feeding them or letting them out of the carrier at airports or on board will be prohibited. Owners will also be asked to have their pet wear a diaper to prevent the smell of their droppings spreading. The airline initially plans to offer the new service on the Kitakyushu-Haneda route. For the time being, the offer will be to one human-animal pair per flight. The only designated seat for the animal, one of some 150 seats in the cabin, is by a window and situated all the way at the back. The case carrying the pet is placed in the window seat while the owner sits next to it. Fees for the new service are yet to be decided.
