Jasfoup loved aircraft flights. He loved the panic among the passengers during take-off, the panic when they hit turbulence and the panic when just one passenger in business class saw him in his true form. Once in a while he got Devious to sit on the aircraft wing, though to be fair he got the idea from an old Twilight zone.
His number one reason for loving aircraft flights, though, was the baggage claim. He would instruct Devious to steal one or two expensive looking suitcases and marvel at how red-faced some people could become. Redder than the fires of... well, not Hell but a good wood-burning stove.
