737-800 climb to FL410

Today I flew the 737-800 From KMCO-KMHT and getting to FL410 was tough from FL380-FL410 I had to climb at 700-1000 FPM climb rate the load percent was Load 70% at Mach.78

I wouldn’t suggest going that high with that load. I would go at FL390 at the most.

Been a while since have seen a plane that high.
