I already know KLM (Royal Dutch Airlines) is pretty, pretty good in creating extra value for their customers. The social media activities of KLM are always spot-on. But this one is my favourite by far: the KLM Must See Map. This social media campaign enables travellers to create a city map that is customized with tips and suggestions from their friends. Ask your friends about the best restaurants and hotspots and receive your own high-quality printed city map at home. (Allow three weeks for delivery.) Oh, and it’s for free! From KLM (with some help of your friends) to you. Check it out!
