It’s that simple:
KLM encouraged people in Amsterdam to high five strangers in New York for a chance to win flights.
Nice use of technology for marketing.
Touch-(or slap-)screens in Amsterdam and New York allowed perfect strangers – 3,600 miles apart – to challenge KLM game and win (both) an economy-class ticket towards the opposite city.
Dutch-based advertising agency Eigen Fabrikaat (DDB Group) used this seemingly easy gesture to send people around the world.
Note: no touch-screens were hurt during this campaign!
