Passengers of charter flights are responsible for the majority of extra costs arising from delays in airport security checks, according to scientific research conducted by airport security consulting company, Kirschenbaum Consulting.
The findings are based on a one-year in-depth study held at a regional European airport. The results indicate that while only 10-15% of scheduled passengers carried prohibited items, 33-50% of charter passengers did so.
Moreover, while only 10% of regular flyers were re-examined by security employees, 33% of charter passengers needed another check. The research, which included both an ethnographic and time-motion study, also showed that, while charter passengers accounted for less than 50%of overall traffic, they were responsible for an additional 35% of the overall security costs.
