Looking for maps

Hello,
I am a professor of digital media and am currently working with
students on techniques for visualizing information systems. I was
hoping that someone could help me find out if there are maps out there
somewhere that might notate the following information:

-Airlanes (skylanes...is that the correct name?) or typical routes of
travel within the US
-Locations or names of air traffic centers in the US

We are attempting to notate and visualize "graphically" the actual
paths of travel of aircraft moving from the west coast to east coast
and vise versa in relationship to the locations of the air traffic
control centers, essentially looking at how an aircraft moves from one
coast to another, where it deviates from a straight line, etc.

Any help you all can offer would be GREATLY appreciated.

Thanks in advance,

Bob Trempe
