Do you have any tips for my flight to Kusatsu?
Wherever you're coming from, flying can be an enjoyable experience if you've prepared well enough. Check out these essential travel tips that will get your Kusatsu holiday started on the right note. What to pack in your hand luggage:
  • It's simple — first, pack your passport, important documents, credit cards and vital medications. Next, you'll need some entertainment to help pass the time. A thrilling novel and a tablet crammed with your favourite shows are good options. If you plan to take a short snooze, a quality neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, leave some space for a toothbrush and some cleansing wipes to ensure you step off the plane looking fresh and raring to go.
Do not pack the following items in your hand luggage:
  • Double-check that you don't have sharp objects (like a pocket knife) hiding in one of the zippers of your hand luggage. Other prohibited items include explosive or flammable substances, such as fuel and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your main priority is to feel as comfortable as you can. Opt for shoes that are easy to pull on and off, dress in loose, breathable clothing and don't forget to bring a pullover in case it gets cold in the cabin.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to improve your circulation.
How to get through airport security fast when flying to Kusatsu?
A little pre-planning before you arrive at the airport can make your trip to Kusatsu quick and painless. We've compiled some useful tips for a swift journey past security:
  • First things first. Your ID and travel documents will need to be presented to airport security personnel. Have them close by so you don't hold up the queue.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • Your electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online before you know it.
  • Any liquids or gels, such as hair oil or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a clever footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and other heavy-style shoes are usually subjected to extra screening.
  • Airlines will not allow any sharp objects in your carry-on baggage. If you must bring these kinds of items, pack them safely in your checked baggage.
