The Department for Transport said the reintroducing restrictions was not in response to a specific threat and would "enable further improvements to be made to the new checkpoint systems"
The change came into effect on Sunday morning and affects regional airports around the UK including including London Southend, Newcastle, Leeds Bradford, London City, and Aberdeen. It has also been introduced at Jersey Airport in the Channel Islands.
The larger and busier airports, including London Heathrow, Gatwick and Manchester are not affected by the change as they still have the restrictions on liquids in place as the new scanners have not yet been installed there.
London Southend Airport stated "passengers travelling through London Southend Airport can still keep everything, including all liquids and large electrical items, in their cabin baggage when passing through security. Any liquids above 100ml will not be permitted to travel and must be voluntarily abandoned. Water bottles can be refilled after Security."
Ports of Jersey advised passengers would need to put all liquids, aerosols, gels and pastes carried in their hand luggage into the security trays for screening, adding that there was "no need" to place them in a plastic bag.
Nick Barton, the chief executive of Birmingham Airport condemned the temporary reinstatement of restrictions saying he was "very disappointed" by the news. He also blamed passengers for the long queues at the airport, telling local media "A non-compliant bag with liquids over 100ml can add up to 20 minutes to each passenger's journey through security."
