Twenty-five years after 9/11 transformed American air travel, the US is cautiously restoring freedoms once considered routine. TSA airport security is moving towards a more technology-led model, with vetted visitors now able to reach gates without boarding passes at 13 airports. The Transportation Security Administration has launched Gateside by TSA PreCheck, allowing eligible PreCheck members to accompany relatives, meet arriving passengers and use post-security facilities. At the same time, the agency is considering whether some travellers could carry full bottles of water through checkpoints. The potential liquids change would mark another major reversal of a restriction introduced after the 2006 liquid-explosives plot. Crucially, the changes retain security screening while relying more heavily on trusted-traveller vetting and advanced detection technology.

A Post-9/11 Restriction Starts To Retreat

The biggest immediate change concerns who can enter an airport’s secure area. Under Gateside by TSA PreCheck, eligible people without flights can apply for permission to cross the checkpoint and enter participating airport terminals.

The programme is free for eligible TSA PreCheck members and other travellers with qualifying Known Traveler Numbers. Applicants must apply online one to three days before their planned visit, receive approval and present acceptable identification at the checkpoint.

Visitors must still pass through TSA screening before entering the secure area. The programme therefore does not remove the security barrier; instead, it expands controlled access beyond it.

The move has particular significance because airports once functioned differently for families and visitors. Relatives could walk departing passengers towards the gate, while friends could wait for arriving travellers inside the terminal.

That experience largely disappeared after 9/11 as airport security became more restrictive. The latest programme represents a carefully controlled attempt to restore part of that atmosphere without abandoning the security architecture built since then.

TSA says Gateside can also support passengers during layovers and encourage visitors to use airport restaurants and shops. That gives the initiative a commercial dimension alongside its family-friendly appeal.

Thirteen Airports Open Their Gates

The programme has begun with 13 airports across the United States. The initial locations combine major international gateways with large regional airports, giving TSA a broad operational sample.

The participating airports include some of America’s busiest and most internationally significant gateways. Los Angeles, Dallas-Fort Worth and Las Vegas could give the programme particularly strong visibility because of their large leisure and connecting passenger markets.

TSA has described the rollout as a phased initiative and expects to add more airports. However, travellers should not assume that every US airport currently offers the facility.

The distinction is important because several airports already operate their own visitor-pass schemes. Gateside by TSA PreCheck is different because eligibility is tied to trusted-traveller status and the programme uses TSA’s screening infrastructure.

PreCheck Takes On A New Role

TSA PreCheck has traditionally been associated with faster and simpler airport screening. Its growing membership base now gives the agency another way to distinguish travellers whose identities and backgrounds have already undergone government vetting.

TSA reported 20 million PreCheck members in 2024, while approximately 3.3 million new members joined during that year. The agency also reported screening 904 million travellers nationally during 2024.

Those numbers underline the scale of the US aviation system. They also explain why even small changes to checkpoint procedures can affect millions of journeys.

The Gateside model effectively extends the value of trusted-traveller status beyond the passenger journey itself. A PreCheck member can now use that status to obtain access to a secure terminal area despite not holding a flight ticket.

That could prove particularly useful for families travelling with children. It may also help relatives assisting elderly passengers or people who need additional support navigating large airport terminals.

For airports, the potential commercial benefit is equally notable. Visitors who would previously have remained landside could now spend money at restaurants, cafés and retailers located beyond the checkpoint.

Water Rules Could Change Next

The second potential policy shift concerns one of the most recognisable features of modern airport security: the liquids restriction. TSA currently requires most liquids, aerosols, gels, creams and pastes in carry-on baggage to comply with the 3-1-1 rule.

Under the existing rule, containers must generally hold no more than 3.4 ounces or 100 millilitres. Travellers must place them in a single quart-sized transparent bag, with one bag permitted per passenger.

Full bottles of ordinary drinking water therefore remain prohibited through the standard checkpoint. Travellers can, however, carry an empty bottle through security and refill it afterwards.

Reports indicate that TSA is examining whether some PreCheck travellers could eventually carry full water bottles through security. The proposal has not replaced the existing nationwide rule, so travellers should continue following the current liquids restrictions unless TSA formally announces a change.

The potential reform is significant because the liquids restriction traces its modern history to a serious security threat. Authorities disrupted a 2006 plot involving plans to conceal liquid chemical explosives inside beverage containers, prompting major restrictions on liquids carried through airport checkpoints.

Any relaxation would therefore send a powerful message about the changing balance between security and convenience. It would suggest that technological improvements could eventually allow screening agencies to assess certain liquids more effectively than they could two decades ago.

CT Technology Changes The Equation

Modern airport security increasingly depends on what machines can detect rather than what passengers are forbidden to carry. Computed tomography technology can generate detailed three-dimensional images of baggage contents, providing screening officers with substantially more information than traditional two-dimensional X-ray images.

TSA has been expanding the use of advanced checkpoint technologies as part of its broader security modernisation programme. The agency’s technology portfolio includes computed tomography systems, explosives detection equipment, identity-verification technology and other screening tools.

That shift could gradually change the logic behind blanket restrictions.

The traditional model often imposed the same inconvenience on almost every traveller because screening technology had limitations. A technology-led system can instead differentiate between risks and apply additional scrutiny where necessary.

This does not mean machines replace security officers. Instead, technology gives officers more information and potentially allows them to focus their attention more effectively.

The trend is already visible in identity screening. TSA reported that facial-recognition technology had been added to 1,407 Credential Authentication Technology units by the end of 2024.

For passengers, the long-term objective is straightforward. Security should remain robust while the physical process becomes less intrusive, less repetitive and easier to navigate.

The Shoes-Off Era Has Already Ended

The latest Gateside initiative does not stand alone. It follows another highly visible change in American airport screening: the end of the nationwide shoes-off requirement for passengers travelling through domestic TSA checkpoints.

The Department of Homeland Security announced the change in July 2025. TSA said the new policy allowed passengers to keep their shoes on while passing through security checkpoints.

That decision ended a practice that had become one of the defining symbols of post-9/11 airport travel. For years, passengers routinely removed footwear before entering screening machines, regardless of whether they represented a specific security concern.

The comparison with today’s approach is revealing.

The pattern suggests a gradual redesign rather than a retreat from security. TSA appears increasingly willing to remove inconveniences when technology, identity vetting or operational controls can provide an alternative layer of protection.

What Travellers Should Do Now

Travellers should treat the new rules as selective changes rather than a nationwide relaxation. Gateside currently operates at participating airports, while the existing liquids restrictions remain applicable unless TSA announces otherwise.

People planning to use Gateside should apply within the required one-to-three-day window. They should also carry acceptable identification and be prepared to undergo the same fundamental security screening applied at the checkpoint.

The programme can be especially useful for families. Someone accompanying a child, helping an older relative or meeting an arriving traveller may no longer need to remain outside the secure area at participating airports.

International visitors should take particular care when planning US connections. Rules can differ between countries, airports and transit arrangements, while airline requirements may also apply independently of TSA procedures.

Travellers should therefore verify the latest rules before departure rather than relying on social-media posts or older airport advice. TSA’s official travel guidance continues to state that standard carry-on liquids must comply with the 3-1-1 requirements.

Airports Could Gain A Commercial Lift

The implications extend beyond passenger convenience. Airports increasingly treat post-security areas as commercial destinations, with restaurants, shops, lounges and other services generating substantial non-aeronautical revenue.

Allowing a controlled number of additional visitors into these areas could therefore create incremental spending opportunities. The effect may be modest at first, but the experiment gives airports another mechanism for increasing engagement with their terminals.

Families could represent one of the clearest beneficiaries. A relative can potentially accompany a traveller closer to the gate, reducing the emotional and practical friction associated with airport departures.

The programme may also benefit airports seeking to create a more welcoming passenger environment. Large terminals can feel intimidating, particularly for first-time travellers, children and passengers requiring assistance.

However, operational capacity will remain crucial. If additional visitors increase checkpoint queues or congest terminal areas, airports may need to introduce tighter controls during peak periods.

That makes the initial 13-airport rollout particularly important. TSA can assess how visitor access affects screening volumes, passenger flows and terminal operations before expanding the programme nationally.

Security Standards Remain The Critical Test

The nostalgia surrounding pre-9/11 aviation is understandable, but nostalgia cannot become the basis for security policy. The more important question is whether modern technology can deliver the same or stronger threat detection with fewer unnecessary restrictions.

Aviation security expert Jeff Price, a professor at Metro State University Denver, told the BBC that improved technology could support such changes without compromising core security standards. He also cautioned against removing valid protections simply to recreate a pre-9/11 experience.

That distinction should remain central as the US reshapes airport screening. Convenience can return only where security remains credible, measurable and enforceable.

The new approach also reflects the changing nature of aviation threats. Security agencies now have access to technologies and identity systems that were unavailable when many of today’s rules were introduced.

The result could be a more targeted security environment. Instead of imposing maximum inconvenience on every traveller, authorities can increasingly combine trusted identities, advanced screening and risk-based intervention.

A Controlled Return To Airport Life

The Gateside programme marks a symbolic moment for American aviation because it restores something that many travellers assumed had disappeared permanently. Selected non-ticketed visitors can once again move beyond security, meet loved ones at gates and experience the airport without holding a flight ticket.

Yet this is not a return to unrestricted pre-9/11 travel. Applicants require approval, visitors must pass through screening and the programme remains limited to participating airports.

The potential water-bottle reform follows the same philosophy. Rather than simply dismantling restrictions, TSA is examining whether better technology can safely replace some blanket rules.

For travellers, the result could eventually mean a smoother and less intrusive journey. For airports, it could create a more welcoming terminal environment and additional commercial opportunities.

For the wider aviation industry, however, the bigger significance lies in what comes next. If the 13-airport experiment demonstrates that trusted travellers and advanced screening can coexist safely, the US could enter a new phase of aviation security.

The goal is not to recreate the airport of 2001. It is to build a safer, smarter and more convenient airport for the decades ahead.
