At VA they are telling us to use CI 10 and 280 kts for descent. To counteract the reduced speed one can go as high as your weight allows.
So the net result SFO/LAX is now flown at FL380 and about .77 or .78. We used to do this leg at FL300 and CI 50. Fuel burns and time are about the same by my observation.
On the transcons, CI 10 means 10 minutes more block time, again flying at max altitude. Again, to me it is a wash. Slightly less fuel flow, for 10 minutes longer equals no real change, again just my personal observation.
BTW, we are supposed to fit the flow on arrivals if ATC asks us. To turn off course instead of speed up is kinda defeating the whole idea to me...
