This is such a hard thing to judge. I've seen data where NYC-FLL route has the most traffic of any domestic market (closely followed by NYC-LAX). Then there are the gillion flights that both UA and AA have ORD-LGA/EWR. And HNL-OGG has a ton of flights as well!
I just tried doing some research on this and stats are hard to come by that answer my questions; however, when looking at congestion maps...the East Coast is much more saturated than the West Coast.
That being said, I do know that the specific LA-SF "market" has a ton of O&D traffic.
