If Air New Zealand reigns supreme when it comes to viral videos, KLM is leading the way in the development of applications and micro-sites in support of the airline's marketing efforts.

The latest initiative is KLM's Dreamcatcher, a mashup site that aggregates practical travel information about destinations KLM flies to.

This information, that is pulled through APIs from twelve of some top content and travel review sites, such as Frommer's, Wikipedia or Tripadvisor, and is presented in a very visual Pinterest-style format.

According to KLM suggestions are presented by order of popularity (I imagine it is popularity among the users of the source content sites).

You can then pick up your favourites and create your own map of things to do and to see that you can then donwload to your smartphone to use when you are in the city of destination.
