Air Wars?

[HapSmo19]

Like any idea not out of far-left field, I'm sure it's been brought up before but how about a map of airline hubs and overlapping routes of major, national and regional or whatever you call em' airlines(like the NYC trains but more airliney ) Could use a world map or a U.S./N.A. map if that works better.
You probably get the idea so I don't need to get to into detail right away do I?

I could probably help with a little research

It'd probably be a lot like the Rail maps. Look at the airport codes for inspiration (LAX, JFK, PHL, SLC, etc)

But you could probably do dueling airlines (they'd be the bonuses) each airline has hub cities and work an angle like that.
