The air pressure inside an aircraft is supplied from the bleed air from the engine's compressor, thus the air inside the cabin is the same air that the engine is breathing. Older aircraft cabins leak profusley and so a constant supply of fresh air flows through the plane. Airbus decided that if the cabin was sealed better and the air recirculated, the engine would work less hard to keep the the cabin pressurized and result in a fuel savings. This spurred complaints about cigarett smoke and the FAA ruled that all domestic flights would be nonsmoking. Consider what might have been the result if the FAA had ruled nosmoking on the Airbus only!
