Many airline passengers say the worst a part of any journey is the airport safety examine. Worldwide, a median of half one million folks cross by way of airport safety each hour. Travellers resent the restrict on LAGs (liquids, aerosols and gels) in cabin baggage, in addition to the duty to extract electronics reminiscent of laptops and tablets from hand baggage.

The liquids guidelines have been launched unexpectedly in 2006 as “a brief measure” to guard in opposition to explosives. Regardless of repeated guarantees they continue to be in place.

In 2019 Boris Johnson vowed the principles 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 1 June 2024. Whereas new scanners are being put in at checkpoints in any respect the UK’s foremost airports – the work was not quick sufficient to fulfill the June deadline.

The large 4 UK hubs – Heathrow, Gatwick, Manchester and Stansted – mentioned some months in the past they might not be prepared in time. The transport secretary, Mark Harper, granted airports an extension, however warned that they could possibly be fined in the event that they additional delay the roll-out of smoother safety.

Every week afterthe deadline, progress in aviation safety really went into reverse, with the Division for Transport (DfT) ordering airports with the brand new tools to revive the outdated 100ml restrict on LAGs.

Simon Calder, former safety officer at Gatwick airport and present Unbiased journey correspondent, explains extra.

Cabin baggage: what are the principles?

The record of things that can not be taken by way of an airport safety checkpoints in carry-on baggage has elevated over the many years. Prohibitions have advanced 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. However there are additionally strict guidelines about bigger portions of liquids, aerosols, gels, pastes, lotions and cosmetics, extending even to yoghurt, smooth cheese and Creme Eggs.

No container for any LAG might be above 100ml. At most airports they have to be carried inside a resealable clear plastic bag with a most quantity of 1 litre, and eliminated for the safety examine, however at seven the liquids might be left within the passenger’s baggage.

How did the liquids rule come about?

In August 2006 the aviation business – and baffled passengers – awoke to seek out safety guidelines for passengers had tightened in a single day. The federal government 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 gadgets on board a variety of plane. The elements, derived from hydrogen peroxide, have been meant to be smuggled aboard in smooth drink containers. The plotters aimed to assemble the bombs on board earlier than detonating them and destroying the aircraft. They have been later convicted of offences together with conspiracy to homicide and conspiracy to trigger explosions.

The bosses of Britain’s airways have 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 have 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 way of the checkpoint, however provided that they tasted it first in entrance of safety employees to display it was the actual factor.

Baggage programs couldn’t deal with two or thrice the conventional variety of gadgets, and Heathrow airport floor nearly to a standstill. Flight networks elsewhere within the UK and Europe have been additionally affected.

Three months later, the principles have been eased – however with strict limits that prevail as we speak at nearly all UK and abroad airports.

Have been they all the time meant to be everlasting?

No. The bounds have been launched as a “non permanent measure” whereas airport safety know-how caught up. However progress has been painfully gradual.

Even a really modest leisure of the principles – to permit airport purchases of drinks to be taken by way of checkpoints in a sealed “safety tamper-evident bag” (Steb) – took years to be applied. Many passengers are nonetheless being caught out, dropping their costly airport purchases, as a result of duty-free drinks will not be allowed by way of the airport the place they alter planes.

Is there a technological resolution?

Sure. Trendy 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 machines can detect potential threats and current safety officers with a three-dimensional picture of the contents.

They’ll additionally analyse whether or not laptops and different digital tools current a hazard.

At airports the place the know-how is put in, liquids and laptops not must be eliminated.

The purpose is that safety needs to be enhanced, with extra subtle evaluation of potential threats. The quantity of employees time consumed in “secondary searches” needs to be decreased, permitting officers to spend extra time assessing passenger behaviour.

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

That sounds nice – so what are we ready for?

The brand new equipment was first utilized in Europe at Shannon within the west of Eire, the place “liquids, gels, pastes, lotions and cosmetics in containers of any measurement” have been allowed by way of safety since March 2022.

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

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

In 2022, the transport secretary Mark Harper mentioned the airport expertise would develop into simpler from 1 June 2024: “The tiny toiletry has develop into a staple of airport safety checkpoints, however that’s all set to vary. I’m streamlining cabin bag guidelines at airports whereas enhancing safety.

“By 2024, main airports throughout the UK can have the newest safety tech put in, lowering queuing instances, bettering the passenger expertise, and most significantly detecting potential threats.”

How did that prove?

Very badly, with the overwhelming majority of airports failing to fulfill the deadline. They embody the UK’s 4 largest airports, which deal with many of the nation’s passengers: Heathrow, Gatwick, Manchester and Stansted.

A senior aviation determine, Jonathan Hinkles, advised Airliner World: “For airports – many nonetheless battling to restore their monetary steadiness sheets after the pandemic – the large price of this new tools is an unwelcome burden.

“The federal government-imposed deadline date disadvantaged them of any actual capability to barter costs with suppliers of the brand new tools, and far of the brand new equipment is popping up late too.”

In April 2024, the federal government mentioned: “We recognise that putting in the brand new safety tools at busy airports has been a logistical problem, with some airports having to undertake vital building work to permit the brand new, extraordinarily heavy tools to be fitted. In some instances, airports have been required to assemble completely new screening halls.”

Mr Harper mentioned: “It’s essential we give these airports but to fulfill the deadline a second probability to get the job achieved.”

The transport secretary mentioned aviation safety regulation could be modified so non-compliant airports could possibly be fined – although that laws was scuppered by the election being referred to as.

Some complied, although?

Sure. Seven airports met the 1 June 2024 deadline: Aberdeen, Newcastle, Teesside, Leeds Bradford, Birmingham, Southend and London Metropolis. As well as, Bristol airport says it’ll have the brand new tools totally in place by 14 June 2024.

They noticed having the equipment in place as a aggressive benefit, with the promise of an nearly full leisure of the liquids rule – with as much as 2 litres being allowed by way of.

However in a shock transfer, from 9 June 2024 they have been ordered to revive the 100ml restrict. It was not a whole reversal; passengers will nonetheless be capable to depart liquids, aerosols, gels, and so forth, of their cabin baggage. They have to, although, be in containers of 100ml or much less.

Why did that occur?

It was not the airports’ selection. At London Metropolis and Teesside, for instance, the brand new scanners have been working nicely for over a yr.

A Division for Transport spokesperson mentioned: “This non permanent transfer is to allow additional enhancements to be made to the brand new checkpoint programs.”

The transport secretary, Mark Harper, was later questioned by the printed media however didn’t reveal rather more. He advised BBC Breakfast: “We’ve reintroduced that rule whereas updates, modifications are made to the scanning tools on the airport to verify we will proceed delivering our world-leading ranges of aviation safety.”

The Unbiased understands the transfer has nothing to do with fears of weaker aviation safety. As a substitute, it outcomes from issues about lengthy queues at UK airports because the summer season rush – amplified by soccer followers departing for Euro 2024 in Germany.

Ministers worry that delays at safety checkpoints might construct up as a result of the brand new tools is mis-identifying many innocuous gadgets in passengers’ baggage as posing a risk.

Sources have advised The Unbiased that innocent liquids reminiscent of sunscreen have been misidentified as high-threat substances.

Whereas safety has by no means been compromised, a variety of airports utilizing the brand new scanners have skilled lengthy queues as a consequence of a higher-than-expected rejection fee, with safety officers obliged to hold out hand searches of cabin baggage.

On a number of events whereas passing by way of checkpoints at non-fully compliant airports with the brand new equipment, I’ve witnessed the system snarling up because of the massive variety of baggage required to bear a hand search – and gone from imagining I had loads of time for a espresso earlier than the flight to sprinting to the gate.

If sunscreen reveals up as a attainable risk, why does the amount matter?

As a result of the 100ml restrict was chosen as a sufficiently low quantity to keep away from an on-board risk. Successfully, the airports with new scanners can cross baggage that may in any other case be rejected. The purpose is to hurry up the method and scale back queues.

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

Not essentially: passenger confusion is a continuing drawback for aviation safety. It was tough sufficient conveying the 2 units of guidelines, “outdated” and “new”, for gadgets carried in cabin baggage. Due to the publicity surrounding light-touch safety at a handful of airports, there are fears that travellers might infer guidelines have modified all over the place.

Worldwide, lack of conformity is a key subject for aviation safety professionals – and passengers.

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

In Israel, procedures are completely completely different. The authorities say: “Passengers ought to arrive three hours previous to departure for the safety examine process.” There’s typically intense questioning by officers, and laptops have to be eliminated. However liquids are permitted with out restriction.

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

Is that this going to price me extra?

The airports which might be collectively investing a whole bunch of tens of millions of kilos will probably be in search of a return – and that might embody elevating charges. However the long-term purpose is that new tech ought to reduce employees prices, representing financial savings for airports.

Willie Walsh, director-general of the Worldwide Air Transport Affiliation (Iata) – representing airways worldwide – mentioned: “Implementing this know-how mustn’t include an enormous invoice. In truth, simplified processes ought to ship vital efficiencies.”

“Speedy deployment needs to be attainable. The know-how has already been used efficiently and for a very long time at numerous airports the world over with measurable enhancements to the passenger expertise.”

Will aviation safety stay a everlasting ache?

No. In 2019 Iata described the prevailing safety state of affairs as “not sustainable”. It has been working with airports for over a decade on a challenge referred to as “Good Safety”.

In the end walk-through steel detectors and safety pat-down of many passengers needs to be eradicated, with know-how assessing attainable threats extra successfully than people watching screens.

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

Checkpoints will nonetheless be staffed, however safety personnel will probably be freed as much as do what folks do finest, which is to check the behaviour of passengers and determine “individuals of curiosity” for additional investigation.

Nonetheless, because the reversal at UK airports present, there’s a lengthy solution to go.
