I've seen you mention wikipedia a couple of times when talking about building awards and figuring out where airlines fly - what exactly do you use wikipedia for?  Have you done a post about this?

I did write one post that touched on using wikipedia: Book Awards Like a Pro: Routing Ideas. But I'll answer the question of how I use wikipedia more fully.

For me, the two best places to get routing ideas are kayak.com and wikipedia.
