Solid toiletries
Avoid packing liquid toiletries of any sort. First, they take up a lot of space and have the potential to spill. Anything in powder form may arouse customs officials’ suspicions that you may be carrying drugs so their investigations may delay your departure or entry at airports. Solid shampoo bars, soaps, and even solid perfume, makeup removers, bug balm, and sunscreen are readily available at most pharmacies or online to purchase. Place plastic wrap under the cap of your toothpaste tube to minimise leakage.
Keep all your personal toiletries in their own bag
If you don’t want to go the solid route, keep your toiletries together in a toiletry bag and decant large bottles into travel-sized ones to limit the amount of space they take up (not to mention adding weight to your luggage). Pop them into a Ziplock bag to ensure they don't leak during your flight. If you wish to take some with you in your hand luggage familiarise yourself with the policy around LAG’s.
Draw up a packing list
Draw up a packing list and cross off each item as you load it into your suitcase. There are also packing lists you can download from the Internet to make this tedious, but essential, task simple for you.
Wear your bulkiest clothing while embarking on the aircraft
Wear your bulky item like a coat, jacket, windbreaker, anorak etc. onto the plane. You can usually make room for it in the overhead locker when you reach your seat. Use its pockets to stow your camera or techno items and their chargers. Wear sneakers or boots with thick socks. You can always take off your footwear on a long-haul flight and since you’ll be seated most of the time this will keep your feet comfortable for the duration of the flight.
Foldable day pack
Include a collapsible day backpack that can fold up small and will take up virtually no space in your luggage. Carrying a small, light backpack allows you to tote a few essential items with you during your day out in your chosen destination while at the same time keeping your hands free.
