Think about all the little bottles you probably shove into your handbag on a normal morning. Your hand cream, that tiny perfume sample from Christmas, and maybe a contact lens solution you meant to refill.
At Heathrow, every single one of those needs to come out of your bag and into a clear plastic bag. Yes, even the travel-sized toothpaste you bought at Boots. The rule is strict: each container must be 100ml or less, and all must fit into a single, see-through bag.
Imagine you’re packing for a picnic. You wouldn’t bring a giant bottle of ketchup that doesn’t fit in your basket, right? Same logic here—your liquids need to be small enough to play nice in that one designated bag.
The Little Disaster You Can Avoid
Picture this: you’re rushing to catch your flight to see your mate in Barcelona. You forgot to prep, so you’re frantically digging through your carry-on while the queue behind you sighs. A security officer hands you a small plastic bag, and you spend two minutes shoving bottles in like puzzle pieces.
If it doesn’t all fit, you have to throw something away. Goodbye, expensive face serum. Hello, regret. Avoiding this tiny drama is why you care—it saves your money, your time, and your dignity.
Nobody wants to be the person holding up the line because they packed a full-size bottle of shampoo. Trust me, I’ve been that person, and the walk of shame to the bin is not a holiday vibe.
