• Firstly, and most importantly, pack in your passport, official ID, bank cards and vital medications. Next, you'll need some entertainment to help pass the time. A juicy book and a tablet filled with your favourite shows are always good options. If you plan to catch up on some sleep, a comfy neck pillow and some noise-cancelling headphones will also come in handy. Finally, leave some space for a toothbrush and some facial wipes to ensure you step off the plane feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

• While the list of prohibited items can differ between airlines, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, drills, aerosol cans and bleaching agents. Sports equipment like baseball bats, and items that could injure passengers, such as guns and swords, won't be allowed on board either.

What to wear on a flight:

• You'll want to choose comfort over style. Prepare for temperature changes in the cabin by wearing layers, and pick flat, slightly roomy footwear like sneakers.
• It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. To lessen your risk on board, drink plenty of water, consider wearing compression socks or tights and keep your feet and legs moving.

It's simple — be prepared. We've rounded up some handy tips and tricks for a speedy trip through security. Watch out Doai Onsen, here you come:

• Your boarding pass and travel ID will need to be shown to airport security. Keep them at hand so you don't have to dig around for them.
• Next up, both you and your hand luggage must be X-rayed. To make the process quick and painless, take off anything that might set the alarms off. Personal belongings such as your jacket, belt and earphones will be required to go through the machine.
• Electronic devices like phones and laptops will also have to go on a tray for inspection. Don't worry, you'll be back online before you know it.
• Any gels or liquids, such as lip balm or cologne, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
• Lightweight sneakers are a great footwear choice as you're less likely to have to remove them when passing through security. Hiking boots and other bulky shoes are usually subjected to additional screening.
• Airlines will not allow any sharp or pointed objects in your hand luggage. If you must bring these kinds of items, pack them in your checked luggage.
