Final answer:
The consequence of implementing airport security inspections is that airline flights take longer to arrive at their destinations after departure due to the intensive security screening process, resulting in longer flight times. This can cause delays and impact passengers' travel plans and schedules, while also leading to additional waiting time for travelers at the airport.
Step-by-step explanation:
The consequence of implementing airport security inspections is that airline flights took longer to arrive at their destinations after departure. Since the 9/11 attacks, security screening has become more intensive, and the procedure takes longer than in the past. This is due to the increased measures and checks needed to ensure the safety of passengers and prevent any potential threats.
This longer screening process can cause delays in boarding and departures, resulting in longer flight times and potentially impacting passengers' travel plans and schedules.
One example of this is the increase in time spent waiting at the airport. According to the United States Department of Transportation, the average air passenger spends an extra 30 minutes in the airport per trip due to security screening. This additional waiting time is an opportunity cost for travelers, as they could have been using that time for other activities.
