Dear Aquadalte

I'll try and explain this in another way. My first comment refers. Flying above (or below) Opt will lead to a higher burn. Therefore flying around at Max (which is perfectly safe due to your 0.3g buffet margin) has nothing to do with economics. No one operates at Max Alt to save the company money. They fly at Opt to do that.

Thanks for the lecture though.
