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!
