<P> The U.S. ban on inflight smoking began with domestic flights of two hours or less in April 1988 , extended to domestic flights of six hours or less in February 1990 , and to all domestic and international flights in 2000 . In March 1995 , the United States , Canada , and Australia banned smoking on international flights traveling between those countries . The 1990 ban applied to the passengers and the cabin of the aircraft , but not the flight deck ; pilots were allowed to continue smoking after the 1990 ban due to concerns over potential flight safety issues caused by nicotine withdrawal in chronic smokers . </P>
