Passengers at Aberdeen International Airport no longer need to remove laptops or liquids when passing through security.
The Scottish airport has become the third in the UK to fully install Next Generation Security Checkpoint (NGSC) Scanners, following Teesside, and London City, where queue times have been cut by 50%.
It means that the previous 100ml liquid rule is no longer in force with departing passengers able to carry bottles containing up to two litres in their hand luggage.
Electrical items like laptops will also be able to be remain in carry-on bags when they pass through the new 3D scanners.
Last year more than 2.3 million passengers passed through the terminal.
Aberdeen airport Security Manager William Wallace said: “We are delighted to have the NGSC scanners operational at Aberdeen. We are well ahead of the deadline set by the Government thanks to all the hard work from our staff and contractors.
“This is one of the biggest changes in airport security so we would ask passengers to be prepared for this new process and to have patience as we enter the biggest change in aviation security in nearly two decades.”
Passengers are reminded that different rules may apply at other UK airports.
“It is important to check what the process is at both your departing airport and any other airports you will travel through or from before you set off, as this may be different,” added Aberdeen.
