The UK Government has set a new deadline for airports across the UK - including Scotland's main travel hubs - which will see the 100ml liquid rule scrapped.
A deadline of June 2024 is now in place to install high-tech 3D scanners, which gives more detailed images of a passenger's luggage. This will allow for the liquid allowance to be bumped up to two litres, and means that travellers will not have to carry small containers in a clear plastic bag.
New rules will also mean passengers will no longer have to remove electrical appliances such as laptops from their bags when going through security.
The Department for Transport said it will lay new legislation around the changes in Parliament on Thursday.
Edinburgh Airport has confirmed that work is underway to install these scanners ahead of the 2024 deadline.
However, it added that passengers should wait until an official announcement is made before bringing larger two litre bottles with them to the airports.
A spokesman for Edinburgh Airport said: "This move is part of our plans and we are currently modelling work for the installation of the scanners into a renovated security hall.
"Most importantly is the reminder to passengers that the 100ml rules remain and will be in place until any announcement and they should continue to prepare for security by removing liquids and placing them into the clear plastic bags provided."
AGS Airports Ltd, which owns Aberdeen Airport and Glasgow Airport, has also confirmed it will follow the government's new changes.
A spokesman for AGS said: "We will always meet the requirements set by the UK Government to ensure our passengers continue to receive the highest standards in security."
The Department for Transport said major airports will be required to install new technology which gives security staff more detailed images of what is in passengers’ bags.
Current airport security rules were introduced in 2006 following a foiled terror plot to blow up planes flying from London to the US with home-made liquid bombs.
Travellers failing to adhere to them is one of the biggest causes of delays at airport security.
Transport Secretary Mark Harper said: “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.
Of course, this won’t happen straight away – this is going to take two years to be fully implemented. Until then, passengers must continue following the existing rules and check before travelling.”
The deadline of June 2024 is being introduced after several trials at airports.
