Full Disclosure: I'd like to see a monthly chart of seats flown between each direct (non-stop) city-pair. How many of those seats were used by 'regular priced' frequent flyers. I'm not sure it's possible to show all connection possibilities.

Then I can see if it's worth trying to stay on one airline to earn miles.

I've done numerous tests of award seat availability on NW and posted it on the "comparisons" section of my web site.
