US airport security weighs major changes 25 years after 9/11

After the 9/11 attacks, American airports underwent significant changes in security procedures. The Transportation Security Administration (TSA) recently announced it will allow individuals without tickets to pass through security and reach airport gates with their loved ones. Additionally, the TSA is considering permitting some US passengers to bring full water bottles through security, reversing a policy enacted following a thwarted 2006 terror plot.

These policy shifts represent some of the most substantial changes in aviation security in decades, according to an aviation expert speaking to the BBC. The changes are primarily driven by advancements in technology rather than a decline in security standards, the expert noted. Passengers who are part of TSA PreCheck or possess a known traveler number will be the first to benefit from these new policies.

These travelers undergo a pre-approval process with the US government to receive expedited security screening at US airports. Individuals with TSA PreCheck who wish to proceed to an airport gate without a ticket can apply online one to three days prior to their intended visit. The Gateside TSA PreCheck program, offering this flexibility, will be available at 13 airports nationwide.

TSA explained that this new initiative aims to facilitate reunions and farewells, allow travelers to enjoy airport amenities, and enhance the overall air travel experience. Aviation security expert and professor at Metro State University Denver, Jeff Price, suggested that the post-9/11 policy modifications were aimed at decreasing the workload of security officers by screening fewer individuals.

However, recent technological advancements have made it possible to reconsider these policies. Apart from reinstating gate visitors, the Trump administration is reportedly exploring the possibility of allowing TSA PreCheck holders to carry water through airport security. This would overturn a ban implemented in response to failed terrorist attacks in the UK in 2006, where individuals sought to smuggle liquid chemical mixtures concealed in soft drink and sports drink bottles.

Price indicated that newer security machines installed by TSA, featuring computed tomography capabilities, can more effectively detect liquid-based explosives. These updates to security protocols come after TSA eliminated the requirement for passengers to remove their shoes during security screenings last year. This unpopular policy had been in place for two decades.

Social media reactions to these announcements were mixed, with some older users expressing nostalgia for a pre-9/11 world while younger users questioned whether the changes signaled a potential decline in safety. Price acknowledged the appeal of returning to a pre-9/11 era but emphasized that these modifications will not compromise passenger safety, provided that core security measures remain intact and standards continue to be maintained at a high level.
