Heathrow Airport, the UK’s biggest airport, has finally completed the installation of a new high-tech CT scanner, allowing passengers to carry up to two liters of liquid in containers while going through security in their bags.

Electronic devices such as laptops can also be kept in luggage, eliminating the need to use clear plastic bags for liquids.

Heathrow Airport says it is now the world’s largest airport, with all terminals fully equipped with new equipment.

but Although it has become the biggest airport to introduce the new high-tech scanner, it is far from the first in the UK, as Gatwick, Edinburgh and Birmingham airports have all been upgraded in recent years, increasing the limit to two liters.

Heathrow Airport said the scanner, which provides a better image of carry-on baggage, will “allow us to serve thousands of passengers per hour significantly more efficiently, while maintaining high safety and security standards”.

The rollout of new high-tech scanners across the UK has suffered a series of setbacks over the past few years.

Prime Minister Boris Johnson pledged in 2019 to abolish rules on liquids being passed through security checkpoints in plastic bags in containers smaller than 100ml by the end of 2022. The pandemic ultimately took its toll.

In December 2022, the Conservative government promised to install state-of-the-art scanning equipment in security lanes by June 2024 in the “biggest overhaul of airport security regulations in decades”.

Then-Secretary of Transport Mark Harper said the reign of “small toiletries” was all but over.

But as it turns out, in June 2024 Deadline not met The largest airports have fewer lanes to sort, and many smaller airports had scanners installed before that date.

And on Friday night, June 13, 2024, the government announced that small airports that have already installed new scanners and scrapped the 100ml liquid rule will need to reinstate those rules. This was the trigger anger between airports operator.

The EU also announced: Return to 100ml rule in July of that year.

Since then, there has been a period of instability. Last summer, the Transport Secretary told passengers: Assuming the 100ml rule is still applied.

Heathrow chief executive Thomas Waldby said the £1 billion upgrade package would allow passengers to “spend less time preparing for security and more time enjoying their journey”.

Passengers should note that this rule change only applies to flights departing from Heathrow Airport and that they should check the airport’s baggage restrictions before boarding their return flight to the UK.
