I just found this great tool Airline route mapper that maps the routes taken by many (but not all) airlines around the world. If you ever wanted to see all the destinations that Continental, sky team or Ural Airlines fly, or which airline flies into Khartoum and from where this tool will help. It's lacking a few things (like some smaller airlines and the newest routes) but I've been looking for a tool such as this for a long time.

Wait a little longer and there'll be a new version coming out.

Great tool. I have been looking for something like this myself. Too bad it is missing everything. I just get pissed trying to figure out what airlines serve a particular airport let alone finding their routes.

THank you

dead link.

this one is ok though.

again, it does not have everything, but a good starting point.
