It looks like a great scheme, but in aeronautical engineering they have something called lift induced drag.
Basicly if you want to exploit the lift of a wing, you'll have to live with its drag as well.


But airplanes are often hypermiling, with flight crew incentives to do so.

Reducing fresh air to the cabine is like switching the car's AC off.
If you're getting a headache aboard, this is often why.

Changes in traffic control have the effect of coasting.
Rather than having approaching aircraft fly stepped approaches where they repeatedly descent and level out in horizontal flight (using fuel and causing noise), ATC improvements are now allowing for continuous descent approaches - "engine on coasting" down to the runway.
