Slowing speeds to save on fuel costs

[cezzna]

A big benefit to flying higher mostly and slower is the eventual harm to the enginges. I've talked to several mechanics who say there is a big difference at overhauls in what needs to be replaced. The higher and slower you go the lower the ITT's and it can make a big difference. I know of companies that extend their TBO's based on proof of this. i'm not saying it's right but it does add to the equation.
