Which London airport is scrapping 100ml bottles?

London City Airport is the first in the UK to scrap the 100ml liquid rule. What's the worst thing about flying? For many, it's having to cram mini-bottles of shampoo, toothpaste and shower gel into an undignified clear plastic bag.



As of January 23, 2026, London Heathrow (LHR) became the latest and largest UK airport to officially abolish the 100ml liquid limit. Following a £1 billion investment in high-definition CT scanners across all four terminals, passengers can now carry liquids, gels, and pastes in containers of up to two liters in their carry-on luggage. LHR joins several other UK airports that have already fully transitioned, including London Gatwick (LGW), Edinburgh (EDI), and Birmingham (BHX). However, travelers should be cautious: many London-area airports, such as London Stansted (STN) and Luton (LTN), still enforce the old 100ml rule as they finalize their equipment upgrades. Always check the specific rules for your return journey as well, as many international airports outside the UK still require the traditional "tiny toiletries" in a clear plastic bag.

You can carry sunscreen in your cabin bags. You will need to limit the volume to equal or less than 100 ml and place them inside a resealable plastic bag. In case travel-friendly containers do not offer you enough sunscreen, it is fine to bring large amounts if you pack them inside your hold luggage.

Pack items that are in containers larger than 3.4 ounces or 100 milliliters in checked baggage.
