Ever since 1998, a variety of Japanese airlines have decorated their jet planes with Pokémon designs. Another has just been announced, as reported by Game Watch, and it features quite the eclectic cast.
Starting May 30th, Skymark will be sending a plane to the skies of Japan featuring Pikachu, Wailord, Magikarp, and Sky Forme Shaymin. It will only be flown domestically.
