Engines TBOs are based on hours flown. If a flight is flown faster, there is less time placed on the engine/airframe. As long as the engines are run at M/C or less (temps etc), there is no harm to the engines. Especially on the engines that are derated so much. Trust me, those AE3007s love flying above .91m
And fuel flows above FL410 are less than 1000pph/each.
Slowing to .84 is like doing 45mph on the interstate.
I agree, you're not going to save much time between .74-.80, you just burn a little more gas. Where if we slow from .90 to .82 it adds substantial flight time.
For the record, our flight crews share operational control of each flight.
