Whereables is a Google Map of the world's airports. Using the map it is possible to find out which airline flies where and how people rate them. Users of the map can comment and rate individual airports, airlines, the food, the facilities, the queues, the crew...the security or the other passengers.
If you click on one of the mapped airports you can view where you can fly to from that location. All the possible destinations are shown by connecting the airports, as seen in the screenshot above.
Hidden away in the blog (click on the 'b' in the side panel) on Wherables is a link to a fun little airport map game. The game involves clicking on the location of a given airport on a Google Map. This is definitely a game for frequent fliers.
