Airplanes don't have to pull over to fill up on air, nor is air charged at $1/litre or whatever, I assume you refer to fuel saving, which would be extraordinarily insignificant. Regardless, the cabin temperature is not controlled by the pilots, but rather by the cabin supervisor with the touch-screens in the cabin, with each "section" of each cabin being individually controlled. If your request ever gets to the pilot they're certainly having a laugh at it
The quantity of air in the cabin, since you appear to refer to that as well, is static, and very carefully controlled, as this determines the pressure altitude of the cabin, usually 3000-6000ft.
If that's the case then the FA did me a disservice, I complained about the excessive amount of air blowing straight at me and she pointed to the ceiling, said it was the a/c and continued on her way. It was so uncomfortable that I even placed a jacket over my head. I was seated on row 19.
On occasions when I asked to "boost the air", the cabin felt hot with no air coming out of the overhead vents.
