UK airlines enforce strict rules about what passengers can carry in their hand luggage, so holidaymakers looking for some winter sun should be aware of the regulations. If you're lucky enough to be travelling abroad for a well deserved break, it's vital to familiarise yourself with key airport rules before setting off. Travellers must adhere to strict hand luggage regulations when flying abroad on any airline, including major operators such as easyJet, Ryanair, TUI, and Jet2. Numerous items are prohibited in your carry-on bags. Passengers must ensure their hand luggage complies with the size requirements stipulated by the airline carrier and refrain from bringing any of the following items on board. Violation of these rules could result in confiscation of the offending items. 1. Liquids Liquid containers exceeding 100ml are not permitted in hand luggage, reports the Express. Any liquids over this limit must be packed in the hold luggage instead, reports Nottinghamshire Live. Travellers carrying liquids up to 100ml in their carry-on must place the items in a transparent, resealable plastic bag, which holds no more than a litre and measures approximately 20cm x 20cm. 2. Exceptions to the 100ml rule Passengers are only allowed to carry liquid containers larger than 100ml through security if they are for essential medical purposes, special dietary requirements, or contain baby food or milk. Duty-free items purchased at an airport or on a plane can also be taken through security, provided they are sealed inside a security bag at the point of purchase and the receipt is visible within the same bag. 3. Lighters Lighters have specific rules too. Travellers are permitted to carry one lighter on board, which must be stored in a resealable plastic bag and kept on their person throughout the flight. It's crucial to remember that lighters cannot be placed in hold luggage or added to hand luggage after screening. 4. Other personal items Items such as corkscrews, knives, large scissors (with blades longer than 6cm), non-safety matches, fireworks, flares and other pyrotechnics, including party poppers and toy caps, cigarette lighters and frozen breast milk, are all banned from being carried in hand luggage. 5. Sports equipment Sports equipment has its own set of rules. Various items, including baseball, softball and cricket bats, golf clubs, darts, walking/hiking poles, catapults, firearms (including replicas), harpoons or spear guns, crossbows, and martial arts equipment, are not permitted to be taken on board flights as carry-on. 6. Work tools Several work tools are not allowed in hand luggage on flights. These include tools with a blade or shaft longer than 6cm, drills and drill bits, Stanley knives, saws, screwdrivers, hammers, pliers, wrenches or spanners, bolt or nail guns, crowbars, and blowtorches. 7. Chemicals and toxic substances Chemical and toxic substances are also prohibited on flights, whether in hand luggage or the hold. This includes oxidisers and organic peroxides, acids and alkalis, corrosives or bleaching agents, vehicle batteries and fuel systems, self-defence sprays, radioactive materials, poisons, biological hazards, materials that could spontaneously combust, and fire extinguishers. 8. Ammunition Ammunition is another item you cannot take as hand luggage. This includes any guns or firearms (including air rifles and starting pistols). You may be able to take them as hold luggage, but it's recommended to check with your airline before travelling. Prohibited items in hand luggage include grenades, fireworks, smoke canisters, smoke cartridges, flares, plastic explosives, and gun cigarette lighters. Each airline has its own set of rules about what items are prohibited in hand luggage on flights. If passengers are unsure about the rules for a specific item, they should contact their airline or travel operator directly for further information.
