Gatwick follows the same UK and EU rule as almost every other airport: liquids in your hand luggage must be in containers of 100ml or less. That’s about the size of a small yogurt pot or a travel-sized mouthwash. And all those little bottles need to fit into one clear, resealable plastic bag—no bigger than 20cm x 20cm (roughly the size of a sandwich bag). Sound strict? It is—but think of it as a game: How much joy can you squeeze into one bag?
You might be wondering, “What counts as a liquid?” Great question! The answer includes everything from water, juice, and shampoo to toothpaste, mascara, sunscreen, and even peanut butter (yes, it’s a liquid in airport logic). The rule is simple: if it can be poured, sprayed, or smeared, it goes in the bag. But here’s the twist—medicines and baby food are exempt, so no stress if you need a life-saving inhaler or a pouch of puree for your little one.
