The rule could be scrapped by 2024, the boss of Heathrow Airport has said.
Currently, liquids must not exceed 100ml and have to be carried in a clear plastic bag.
The upcoming change to the rule has been described as ‘a game-changer’ by airport insiders.
New 3D scanning equipment will be deployed across UK airports to negate the need for the over 100ml-ban.
Major UK airports have reportedly been given a deadline of mid-2024 to install the high-tech devices.
As well as liquids, laptops would no longer have to be removed from hand luggage under the new plans.
John Holland-Kaye, the chief executive of Heathrow, told The Times: ‘We are slowly rolling them [the 3D scanners] out.
‘We have just started the expansion of the security area in Terminal 3 which will have more CT scanners and have a deadline of mid-2024 from the DfT. By then the normal passenger experience will be that liquids stay in bags.’
