As summer travel approaches, UK airlines including Jet2, British Airways, easyJet, Ryanair, and TUI are reminding passengers of strict alcohol regulations. Under UK aviation rules, passengers cannot carry alcoholic beverages with an alcohol by volume (ABV) exceeding 70% in either hand or checked baggage. Alcoholic drinks with an ABV between 24% and 70% are permitted, but limited to a maximum of five litres per passenger in retail packaging. Some high-proof spirits, such as certain overproof rums and grain alcohols, can exceed the 70% limit, posing a risk of confiscation at security. The UK Civil Aviation Authority has implemented these rules due to the increased flammability of high-strength alcohol. Airlines explicitly state that compliance with these regulations is essential for safety. Passengers are urged to check the ABV on labels of spirits purchased abroad to prevent issues during travel. This precaution is particularly important for holidaymakers returning to the UK with local spirits.
