Airports throughout the United States and Canada are increasingly becoming smoke-free, according to a new survey.
Airports Council International-North America said that of the 59 airports that responded to its latest survey, 18 had banned smoking. The results of the survey were released last month.
In a survey conducted in 1993, only five had adopted such a policy. Among other airports responding to the new survey, 37 had established designated smoking areas, and four had no policy on smoking.
At Baltimore-Washington International Airport, as well as the three major airports in the New York area -- Kennedy International, La Guardia and Newark International -- smoking is permitted in designated areas.
