Airport security screening, and the amount of time it costs travelers, has been a persistent concern to travelers. Airport authorities, and airlines particularly in recent years with the prosper of cheap flight which cost extra fees for baggage, there’s been a 27% increase in roller-bag carry-on at checkpoints that have caused great uncertainty relating to security transit times, which could cause delays and inconveniences for travelers and for airport operators. During holidays and summer periods, airports will have to reduce sophisticated electronic screening and resort to less sophisticated screening to avoid causing operation delays.
