“Pilots don’t control the airflow to save on costs, they control the air temperature to save fuel costs.”

I don’t understand your statement. In the jets I fly there is a thermostat that controls cabin temperature. The range is from about 65 to 85 degrees. It modulates a valve that controls the cooling effect on the air used for pressurization. The fuel flow meters do not change in the slightest as I change the temperature.

What is the basis for your statement?

I recall reading stories (perhaps a myth) that pilots were not running the air conditioners in order to save fuel.

I just did a short Google search, and found some articles on older Boeing 747s where this was possible.
