UPDATED 30/04/2024:

It has been announced that the deadline for airports to install the new security scanners, that would see an end to the 100ml liquid rule, will not be met. Earlier this month, the Department for Transport allowed a 12 months’ extension for airports across the UK.

While it has not been confirmed, it can be assumed that Heathrow, Stansted, Gatwick and Manchester will not be ready by this year’s summer deadline. However, London City and Luton Airport are believed to have the scanners in place.

Confusion on the liquid rule could cause delays over the summer if travellers are not aware of the extension and try to pass through security with the incorrect liquid limit. Peter Campbell, head of public affairs at Airports UK, has advised ‘stick to the 100ml liquid rules and you can’t go wrong’.

Gone are the days where you cram your toiletries into a clear plastic bag and sacrifice those that are over 100ml at security. Well, almost. Last year London City Airport ditched the 100ml liquid rule and this year both Luton Airport and London’s Heathrow are planning to follow suit.

New high-tech scanners are expected to be installed in the two London airports in time for the summer holidays. The CT scanners means passengers will be able to carry over 100ml of each liquid in their hand luggage.

According to The Standard, Gatwick and Stansted Airport will miss the summer deadline with Gatwick not expected to have the new security measures in place until spring 2025. If you are travelling from either airport, you will still need to stick to the 100ml rule.

While you will be able to leave the country with over 100ml of each liquid, this may not be the case for your return journey. Amsterdam Airport Schiphol and LaGuardia Airport in the US already have the scanners in place but other international airports may still require you to adhere to the limit.

The new measures are expected to streamline queuing times and improve the airport experience. In addition, security will be enhanced and having the latest technology in place will detect potential threats more effectively.

Delays at security have been known, previously, to cause people to miss their flights despite them arriving at the airport in plenty of time. With costs relating to this not being covered by travel insurance, the reduced queuing times will be welcomed by many, if not all, travellers.
