London Heathrow is now the largest airport in the world to fully roll out next-generation CT security scanners.
Thanks to a £1billion upgrade, passenger security lanes across all four of Heathrow’s terminals have been replaced.
The updated technology means that passengers will no longer have to take liquids or electronics out of their hand luggage before heading through security.
The 100ml rule has been scrapped too so travellers can leave liquids in containers up to 2 litres in cabin bags.
