KLM are always ahead of the game when it comes to social media marketing and their latest campaign leverages the current popularity of Airbnb to create some serious buzz. They've converted one of their planes into the ultimate listing and positioned it in Schipol airport. You can't pay to stay there but instead enter to stay on one of three nights as part of a competition. Not going to make them any money but it is going to blow up on social and get them serious branding for a pretty cheap cost. Super creative campaign. Who wouldn't want to stay on their very own plane?
