U.K. Airports Imposing Restrictions on Liquids Once Again, Leading to Confusion

The United Kingdom has updated regulations regarding liquids in carry-on baggage at airports nationwide — and during the peak travel season, to boot.

Let’s take a look at the details of what’s going on and what you need to know if you plan on visiting.

U.K. Tightening Liquids Policies Again at Several Airports

Liquids in carry-on baggage have long been a thorn in travelers’ sides on both sides of the Pond. In the U.S., we’ve gotten accustomed to removing liquids that are greater than 3.4 ounces in volume (as well as laptops) when going through “regular” security checkpoints.

The U.K., on the other hand, has long had the so-called “100ml Rule,” which barred liquids in excess of 100 ml (~3.4 ounces) from carry-on baggage when traveling through the nation’s airports. The country made attempts at loosening these rules by allowing travelers to carry up to 2 liters (~68 ounces) and to keep laptops inside carry-on bags.

However, the entire operation hinged on whether airports could successfully implement new, Next Generation Security Checkpoints. Back in 2019, then-Prime Minister Boris Johnson set a deadline of 2022 for the implementation and usage of these new scanners. However, that deadline came and went and was then extended to June 1, 2024.

As of the June 1, 2024, deadline, 6 airports were up and running with the new scanners: Leeds Bradford (LBA), London City (LCY), Aberdeen (ABZ), Southend (SEN), Teesside (MME), and Birmingham (BHX).

While these airports were able to get their new scanners up and running — and thus scrapped the 100ml Rule — others, including Gatwick (LGW) and Heathrow (LHR) Airports in London and Manchester Airport (MAN), still do not have the new equipment operational, according to BBC reporting.

This led to traveler confusion across the country because some airports didn’t have the rule in place while others did.

Last month, in June 2024, the U.K. Department for Transport made a sweeping decision that all airports would once again have to abide by the original 100ml restriction, with practically no advance notice. And reporting from The Guardian suggests that these rules will remain in place at least until June 2025 to give all airports more time to implement the appropriate scanning equipment.

Predictably, this led to airports scrambling to adjust their protocols and even more confusion among flyers. Major delays occurred at airports across the U.K., all while travel to Europe is reaching record highs during the summer season. Details remain sparse, with the latest from government officials saying the new restrictions will be in place at least through the summer.

Mark Harper, Secretary of State for Transport, said on June 8, 2024, that the snap decision “only affect[ed] 6 regional airports and about 6% of those traveling. For most passengers, actually, the rules haven’t changed at all yet and won’t therefore change tonight. People should just check what the rules are or the processes are at a particular airport.”

What To Do if You’re Heading to the U.K.

For the time being, if you travel through airports in the United Kingdom, you’ll need to abide by the 100ml Rule. Clearly, these regulations are in flux, so we advise staying as up-to-date as possible by checking the official social media accounts of the airports you’ll be flying to, from, or through. For example, Birmingham Airport has posted numerous times on X (formerly Twitter) advising passengers that they must check or dispose of liquids in excess of 100ml.

Final Thoughts

If you’re planning to visit the U.K. this summer, it’s safe to assume that you’ll be limited to 100ml containers of liquids in your carry-on baggage. If you must travel with amounts in excess of that, you’ll want to check your luggage.

Stay tuned for more updates on this unfolding story — we’re sure there will be plenty more in the near future.
