Do you have any tips for my flight to Kusatsu Onsen?
- First and foremost, put in your passport, official ID, bank cards and medications. Next, you'll want some extra in-flight entertainment to while away the hours. A thrilling book and a phone crammed with your favorite shows are good options. If you intend to catch more than just forty winks, a quality neck pillow and a pair of noise-canceling headphones will also be useful. Finally, leave space for a toothbrush and some cleansing wipes to ensure you arrive feeling fresh as a daisy.
- While the list of restricted items can differ between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes screwdrivers, drills, fuels and bleaching agents. Sports equipment like golf clubs, and items that could harm other people, such as firearms and swords, aren't allowed in the cabin either.
- Your top priority is to feel as comfortable as possible. Go for a pair of slip-on shoes, dress in loose, breathable clothing and remember to take a pullover in case you get cold in the cabin.
- Most travelers have heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To minimize your risk on board, stay hydrated, consider wearing compression tights or socks and keep your feet and legs moving.
How to get through airport security fast when flying to Kusatsu Onsen?
- Security personnel first need to check that you have a valid passport and matching boarding pass before you can proceed any further. Have them ready to show.
- Next up, both you and your hand luggage must be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Personal belongings such as your belt, coat and earphones need to go through the machine.
- Electronic devices like laptops and phones will also have to go through the machine for inspection. Don't worry though, you'll be back online soon enough.
- Any liquids or gels, such as toothpaste or perfume, that you want to bring on board must be no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-close bag.
- The right choice of footwear can save you several precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Lightweight sneakers usually aren't.
- Airlines will not allow any sharp objects in your carry-on luggage. If you must bring these kinds of items, check them in.
