TG,

While it's not my favorite reference read page 172 of Aerodynamics for Naval Aviators. Aerodynamically, the airframe doesn't care what altitude it's at for endurance. But the jet engine's efficiency is much improved and specific fuel consumption is much less at altitude.

I believe that's where the disconnect lies.
