Travellers flying from Bristol Airport are now experiencing a significant change to long-standing airport security rules, as the familiar 100ml liquid restriction begins to disappear at selected UK terminals.
Passengers have traditionally been limited to carrying liquids in containers no larger than 100ml in hand luggage, even if the bottle was only partially full. However, evolving security technology means that guidance now varies depending on the departure airport.
What has changed at Bristol Airport?
Bristol Airport introduced updated security procedures, allowing passengers to carry containers holding up to two litres of liquid within their cabin baggage.
One of the most noticeable changes is that liquids no longer need to be removed from hand luggage or placed inside clear plastic bags when passing through security. Electronic items such as laptops, tablets and mobile phones can also remain packed away.
The change follows the installation of advanced computed tomography (CT) scanners, which produce detailed 3D images of cabin baggage to help security teams identify contents more efficiently.
Rules still vary across the UK
Despite the progress at Bristol and several major airports, many UK terminals continue to enforce the traditional 100ml limit and require liquids to be placed in a transparent resealable bag of around one litre capacity.
Airports including Heathrow, Gatwick, Birmingham, Edinburgh and Bristol have begun relaxing the restrictions, while others — such as Manchester, Luton, Newcastle and several regional hubs — are yet to complete the rollout and still operate under previous rules.
Because of these differences, passengers are advised to confirm the security requirements of their departure airport before travelling.
Exemptions remain in place
Certain items are not affected by the general restrictions. Essential medicines, baby milk and food, along with products required for specific dietary needs, are still permitted in reasonable quantities.
The new scanners use enhanced X-ray imaging to create layered views that can be rotated and analysed, helping security staff assess these items without the need for passengers to unpack their belongings.
Advice for travellers heading abroad
Shaun Jones of Swindon Travel Hub commented: “The easing of liquid restrictions will certainly make the airport experience smoother for many passengers, but the key message is not to assume every airport is operating the same rules just yet. Checking the departure airport’s guidance before packing can prevent delays at security.”
With technology upgrades continuing across the country, travellers can expect a gradual transition away from the long-standing 100ml limit — though preparation remains essential while policies differ between airports.
