The weekend security breach at Pearson International Airport should serve as a warning to anyone concerned about airport security, an airline industry spokesperson says.

 




“We find different procedures at different airports throughout the world,” said Steven Lott of the Montreal-based International Air Transport Association, which consults on airport security internationally.

 




“Why do you have to remove your shoes in the U.S. before you’re screened, but not in other countries? Why do some airlines and some destinations have secondary screening, but not others? What we want is harmonization of security around the world.”

 




Lott raised the questions after knives slipped past Pearson International Airport’s security, 24 hours apart, bound for the same flight. They were caught by Air India’s mandatory screening.
