Aircraft air quality suffered with the ban on smoking.

Cabin air is provided by using engine bleed air and regulating its outflow. Nicotene and soot often fouled the outlet valves and required regular cleaning. Also the bleed air represented a albeit small, decrease in engine efficiency.

With the introduction of smoking ban the cabin air required less circulation (replacement) resulting in better efficiency and reduced fuel costs. The down side is that with less circulation the air became more stale and prolonged passenger exposure to airborne toxins.

Rather than reducing flights or passenger numbers, the solution lies in improving the air circulation methods without adversely affecting fuel efficiency.
