Safety concerns hang over global airlines conference in Mexico

CANCUN, Mexico - A deadly attack in London and debate over travel restrictions in the United States put safety concerns high on the agenda as global airline executives gathered on Sunday for the industry's largest meeting of the year.

Alexandre de Juniac, director general of the International Air Transport Association, said the weekend's violence in London could discourage potential visitors as similar attacks did in Europe last year.

"In previous events, in Brussels or in Paris, the traffic has reduced coming from certain regions of the world," de Juniac said in an interview. "So it's possible that there is an impact, but it's a bit early to know how big this impact will be."
