The 12 UK airports with 'new' security rules - full details ahead of your holiday

If you're going on holiday soon, make sure you know the new security rules of the airport you're travelling from.

The liquid limit was introduced in 2006 after a failed plot to blow up flights travelling from to America, with terrorists planning to use bottles of liquid to assemble a bomb on board.

Liquids over 100ml were banned from flights, alongside all weapons and soft foods. This was initially intended as a "temporary measure" while technology caught up.

In 2019, vowed to ease restrictions on 100ml liquids and electronics, allowing people to carry more and keep them in their carry-ons during security.

But in 2024, the Department for Transport ordered airports to go back to the old 100ml limit, even if they had installed the new scanning equipment, due to not all airports having them yet.

Despite this, there are a number of airports where passengers can keep their sub-100ml liquids and electronics in their hand luggage during security checks.

Staff use CT machines (like in a hospital) to scan luggage, analyse the molecular structure of its contents, create an X-ray image, and detect potential threats.

The aim of this is to improve security, reduce waiting times, and free up staff from secondary searches so they can focus on assessing passenger behaviour.
