The way airline security has been organized since 9/11 imposes an enormous burden on passengers both in terms of money and time. The International Air Transport Association (IATA) estimates that the cost of security has risen to at least €6 billion ($7.4 billion) a year.
It takes passengers longer and longer to get through security. Before 9/11, the average throughput of an airport security checkpoint was 355 passengers per hour. By adding ever more bureaucracy this average has more than halved to 149 passengers per hour.
