Post-9/11 travel security loosens as gateside access expands and screening tech improves

Decades after 9/11, the U.S. is easing some traveler restrictions (shoes can stay on; liquids rules persist) while expanding screening tech and programs. New scanners let travelers leave liquids in their bags, and options like TSA PreCheck and Clear offer expedited screening. TSA also launched a Gateside program allowing eligible travelers to access gate areas without a boarding pass at 13 airports, though not universally available and applications take a few days. The agency scrapped its TSA Gold+ privatization plan in favor of a screening-partnership approach, amid ongoing security challenges from AI, cybersecurity, and drones.
