Cardiff Airport passengers can now carry some liquids in their hand luggage while going through security.
The Rhoose airport has introduced Next Generation Security scanners in the terminal building.
It means up to 100ml of liquid can now be kept inside bags and cases, along with all electronics.
The scanners were meant to be introduced by 1st June under a UK Government deadline, but that was missed by a number of airports - including Cardiff - who blamed supply chain issues and applied for an extension.
Airport chiefs it will make the scanning process quicker and provide "an enhanced customer experience".

Spencer Birns, Cardiff Airport's chief executive, said: "I would like to say a special thank you to our teams for working tirelessly to deliver this project."
"This state-of-the-art facility is a significant investment for the growth and future development of our national airport. Safety and security is our number one priority. We have worked closely with our suppliers, who I also want to thank for their hard work and support."
