Which screening change was implemented to increase screening scope after ATSA 2001?

• A. Screen all checked bags.
• B. Screen all carry on and passengers.
• C. Screen no bags.
• D. Screen only international travelers.

Answer: (B)

Expansion of screening at security checkpoints to include every passenger and all carry-on items. After ATSA 2001, the security focus shifted to universal checkpoint screening, making sure that each traveler and their carry-on belongings go through the screening process to detect prohibited items before boarding. This broadened scope improves threat detection by not limiting screening to certain bags or groups. While screening of checked bags became more stringent over time, the immediate emphasis following ATSA 2001 was on screening all passengers and their carry-ons, which is why the option describing screening all carry-on baggage and all passengers is the best fit. It isn’t about screening only checked bags, no bags, or restricting to international travelers.
