Several UK airports have installed new scanners allowing passengers to leave liquids and other items in their hand luggage at security, such as laptops.
However, the Department for Transport on Thursday (4 April) confirmed not all airports would meet the 1 June deadline to upgrade their security equipment.
Airports will be offered extensions of up to a year on a case-by-case basis, with the DfT citing factors such as global supply chain issues and logistical challenges for the hold-ups.
