On the page that displays all the current flights between, say, JFK and LAX, it would be neat if there was a link to a map that displayed all the current flights between those two airports, and only those planes. Just an idea. 
I kinda said the same thing but I put that with the fleet tracking that way you can track all the flights of that fleet. But I also like your idea.
Right, it’s a similar idea, except instead of mapping all CO planes, you map all planes going between airport A and airport B, of any operator.
