Airport uses scanners to scrap liquid rules

April 4, 2023


London City Airport has scrapped the 100ml liquid limit by introducing high-tech scanners.

the new kit also allows passengers to keep electronic devices in hand luggage at security.

Air travellers can now carry on up to two litres of liquid and toiletries without having to place them in clear plastic bags prior to scanning.

The government has set a deadline of 2024 for British airports to install machines.

Rules were tightened in 2006 in the wake of the 9/11 attacks when all airports were placed on high alert for fear of a repeat of the 2001 terror attack in New York.

British police were afraid terrorists could contruct bombs using liquids inside the cabinc of aircraft.

Officers had foiled up to 10 attacks where drinks would have been employed.

London City Airport has brought in C3 scanners which takes high-resolution 3D images of bags.


The rules proved massively unpopular with customers and cuased long queues at departures.

Chief operating officer Alison FitzGerald said screening staff had been retrained to use the technology.

She added: “The level of processing now through the X-ray is even more secure than it was previously and the machine has the ability to differentiate to between a non-dangerous and a dangerous liquid.

“The whole process is quicker on the basis that previously you needed to empty your bag and put that in multiple trays whereas now it’s one bag in one tray and you don’t need to take everything out,” she said.

Which? consumer expert Harry Kind told the BBC: “It’s really important passengers actually check what the rules are for the airports they’re flying from and flying to.

“This change will make a massive difference and reduce the number of people missing flights and losing out on their holidays just because they’ve got a too big bottle of shampoo.”

Both Heathrow and Gatwick airports have been trialling 3D scanners – a technology made vastly more complicated because of the volume of passengers they have to deal with each day.
