Hmm... I don't think they own the right to the Braniff airline
name. They have the right to name their production company Braniff for the same reason that one of our local plant nurserys is called "McDonald's Nursery" - no one is going to confuse a nursery with a fast-food restaurant, and no one is going to call Trey Parker and Matt Stone looking for airfare to Honolulu. That brings up an interesting point, though - they play that little Braniff commercial at the end. They had to go to SOMEBODY to get the right to run that. Maybe I should have asked this at the South Park forum rather than airliners.net.
