Many airline passengers say the worst a part of any journey is the airport security verify. Worldwide in regular instances, half 1,000,000 folks cross by means of airport security each hour. Travellers resent the restrict on LAGs (liquids, aerosols and gels) in cabin baggage, in addition to the duty to extract electronics akin to laptops and tablets from hand baggage.

The liquids guidelines had been launched unexpectedly in 2006 as “a temporary measure” to guard towards explosives. Despite repeated guarantees they continue to be in place.

In 2019 Boris Johnson vowed the foundations could be eased at main UK airports by 2022, permitting bigger portions and eliminating the necessity to have liquids individually scanned. Rishi Sunak’s authorities then prolonged that deadline to June 2024.

New scanners are being put in at checkpoints in any respect the UK’s primary airports – however not quick sufficient to satisfy the June deadline. The greatest UK hubs say they won’t be prepared in time. The transport secretary, Mark Harper, has given airports an extension, however warned that they may very well be fined in the event that they additional delay the roll-out of smoother security.

Simon Calder, former security officer at Gatwick airport and present Independent journey correspondent, explains extra.

Cabin baggage: what are the foundations?

The listing of things that can’t be taken by means of an airport security checkpoints in carry-on baggage has elevated over the many years, evolving in response to terrorist assaults – profitable and in any other case.

All weapons, whether or not firearms, knives or explosives, are banned from hand baggage. But there are additionally strict guidelines about bigger portions of liquids, aerosols, gels, pastes, lotions and cosmetics, extending even to yoghurt, delicate cheese and Creme Eggs.

No container for any LAG could be above 100ml, and so they have to be carried inside a resealable clear plastic bag with a most quantity of 1 litre.

How did the liquids rule come about?

In August 2006 the aviation business – and baffled passengers – awoke to seek out security guidelines for passengers had tightened in a single day. The authorities introduced that it had uncovered a terror plot to explode transatlantic jets from Heathrow to North America.

The perpetrators aimed to take the elements for improvised explosive units on board numerous plane. The elements, derived from hydrogen peroxide, had been supposed to be disguised in delicate drink containers. The plotters aimed to assemble the bombs on board earlier than detonating them and destroying the airplane. They had been later convicted of offences together with conspiracy to homicide and conspiracy to trigger explosions.

The bosses of Britain’s airways had been referred to as within the early hours of 10 August 2006 to be advised their passengers could be banned from carrying something greater than a handbag or pockets into an plane cabin. Even pens had been banned from transatlantic flights, on the grounds that the ink they contained was a liquid.

One concession was made, for nursing moms: they may take milk for his or her child by means of the checkpoint, however provided that they tasted it first in entrance of security workers to display it was the true factor.

Baggage techniques couldn’t deal with two or 3 times the traditional variety of gadgets, and Heathrow airport floor nearly to a standstill. Flight networks elsewhere within the UK and Europe had been additionally affected.

Three months later, the foundations had been eased – however with strict limits that prevail in the present day at nearly all UK and abroad airports. The limits had been launched as a “temporary measure” whereas airport security know-how caught up. But progress has been painfully sluggish.

Even a really modest leisure of the foundations – to permit airport purchases of drinks to be taken by means of checkpoints in a sealed “security tamper-evident bag” (Steb) – took years to be carried out.

Many passengers are nonetheless being caught out, shedding their costly airport purchases, as a result of duty-free drinks should not allowed by means of the airport the place they modify planes.

Is there a technological resolution?

Yes. Modern scanners use computed tomography (CT) – the identical know-how as medical scanners – to analyse the molecular construction of the contents of a passenger’s bag. The nachines can detect any potential risk and current security officers with a three-dimensional picture of the contents.

They may analyse whether or not laptops and different digital tools current a hazard.

At airports the place the know-how is used, liquids and laptops not need to be eliminated. The equipment was first utilized in Europe at Shannon within the west of Ireland, the place “liquids, gels, pastes, lotions and cosmetics in containers of any size” have been allowed by means of security since March 2022.

Teesside airport and London City airport are additionally now totally up to date.

Travellers have a a lot simpler expertise: they not want deconstruct their cabin baggage, and the entire airport course of feels a lot simpler.

Security is additionally enhanced, with extra refined evaluation of potential threats. The quantity of workers time consumed in “secondary searches” is lowered, permitting officers to spend extra time assessing passenger behaviour.

To scale back stress for passengers and enhance security, in 2019 the federal government advised all main UK airports to have superior CT scanners at security checkpoints by 1 December 2022. But the deadline was missed.

During the Covid pandemic, airports confronted catastrophic losses as passenger numbers collapsed. The obligation to make the multi-million pound funding required was lifted.

But smoother journeys at the moment are again on the desk?

Yes. In 2022, the transport secretary Mark Harper mentioned the airport expertise would change into simpler from June 2024: “The tiny toiletry has become a staple of airport security checkpoints, but that’s all set to change. I’m streamlining cabin bag rules at airports while enhancing security.

“By 2024, major airports across the UK will have the latest security tech installed, reducing queuing times, improving the passenger experience, and most importantly detecting potential threats.”

Some airports, together with Luton and Birmingham, are heading in the right direction to satisfy the June 2024 deadline. But the UK’s 4 greatest airports is not going to be prepared.

When everybody is prepared, will that be the top of issues?

Not essentially: passenger confusion is a relentless drawback for aviation security. Nothing has modified but, although some travellers could infer that it has.

Worldwide, lack of conformity is a key problem for aviation security professionals – and passengers.

At many airports liquids are restricted however can keep within the traveller’s bag. Laptops and tablets akin to iPads have to be eliminated within the UK and plenty of different international locations, however in some nations they needn’t be.

In Israel, procedures are completely completely different. The authorities say: “Passengers should arrive three hours prior to departure for the security check procedure.” There is generally intense questioning by officers, and laptops have to be eliminated. But liquids are permitted with out restriction.

The primary problem: passengers mustn’t count on aviation security to be the identical worldwide – and even UK-wide. At some small Scottish airports together with Barra, Campbeltown and Tiree there have been no security checks since 2017.

Is this going to value me extra?

The airports which can be collectively investing a whole lot of hundreds of thousands of kilos will likely be looking for a return – and that might embody elevating charges. But the brand new tech ought to reduce workers prices, representing financial savings for airports.

Willie Walsh, director-general of the International Air Transport Association (Iata) – representing airways worldwide – mentioned: “Implementing this technology should not come with a big bill. In fact, simplified processes should deliver significant efficiencies.”

“Speedy deployment should be possible. The technology has already been used successfully and for a long time at various airports across the world with measurable improvements to the passenger experience.”

Will aviation security stay a everlasting ache?

No. In 2019 Iata described the prevailing security state of affairs as “no longer sustainable”. It has been working with airports for over a decade on a mission referred to as “Smart Security”.

Ultimately walk-through metallic detectors and security pat-down of many passengers needs to be eradicated, with know-how assessing potential threats extra successfully than people watching screens.

The passenger ought to be capable of stroll unchallenged alongside a hall flanked by detectors, barely conscious that they’re being checked.

Checkpoints will nonetheless be staffed, however security personnel will likely be freed as much as do what folks do greatest, which is to check the behaviour of passengers and establish “persons of interest” for additional investigation.
