Know that rules are in flux
For many years, the standard approach at European airports was simple: small containers of liquids, gels and pastes in a single clear, resealable bag, taken out at security. New-generation scanners are now being rolled out at a growing number of airports, and some of them allow larger containers or let you leave liquids in your bag. The catch is that the rules are not the same everywhere, and they can change at short notice.
The safest approach is to check the website of your departure airport, and of your return airport, a few days before you travel. If you are unsure, pack as if the traditional small-container rule applies. That way you will not lose a favourite product at the checkpoint on the way home.
Decant, do not buy duplicates
Refillable travel bottles are inexpensive and save you from buying a new set of miniatures every trip. Silicone squeeze bottles are good for shampoo and conditioner, while small pots with screw lids suit creams. Label each one, because two unlabelled white bottles will eventually lead to conditioner in your hair twice.
Fill bottles only about three quarters full. Pressure changes in the cabin can push liquid out of a full container, and a little air space gives the contents room to expand.
Switch to solids
Solid shampoo bars, conditioner bars, solid deodorant, bar soap and toothpaste tablets are increasingly easy to find. They do not count as liquids at security, they cannot leak, and they last a surprisingly long time. A small tin or a cut-down soap box keeps them tidy.
Powder sunscreen, stick sunscreen and solid perfume are other useful swaps if you are travelling somewhere sunny with only hand luggage.
Leak-proofing and placement
Put a small square of cling film under the lid of any bottle before screwing it shut, then place everything inside the clear bag. Keep that bag at the very top of your cabin luggage or in an outside pocket, so you can pull it out quickly if asked. Medication in liquid form and baby food are normally treated differently from general liquids, but you may need to show them separately and carry proof that you need them.
Remember that duty-free liquids bought after security usually come in sealed bags; keep them sealed with the receipt if you have a connection.
Good to know
- Check both your outbound and return airport's liquids rules before you pack.
- Leave a little air in each bottle to reduce leaks from pressure changes.
- If your hotel provides basics like shampoo, you may not need to pack them at all.
