"Little Britain" co-stars David Walliams and Matt Lucas turn their comic sensibilities to the world of air travel in this mockumentary series that pokes fun at flying the friendly skies. Walliams and Lucas put the show's makeup artists and costume designers through the wringer as they portray nearly 50 different characters who work at or pass through the fictional airport's imaginary terminal, from pilots, stewardesses and baggage handlers to coffee-kiosk workers and assorted traveling couples.
