My company only used trip winds. All this is assuming you can top it across and not go above mtow of the day.

Thanks.
I should have included that: Hawker, but any turbofan will do for this quiery.
I was probably not clear enough though. Not seeking procedural,
just the general “differences” in fuel totals people have observed over the years for their own turbofans after having flown westbound trans-cons both high & low.
Fuel consumption % differences observed between the two altitudes, after having done so many over the years. Ballpark....
