Do you have any tips for my flight to Kusatsu?
We've rounded up all the info you need to make your flight as enjoyable as possible. Follow our tips and you'll be zooming through airport security and having a ball in Kusatsu in no time flat. What to pack in your hand luggage:

  • First and foremost, put in your passport, travel documents, bank cards and daily medications. Next, you'll want some extra in-flight entertainment to while away the hours. A juicy book and a phone crammed with your favorite movies are some terrific options. If you plan to catch up on some sleep, a comfy neck pillow and some earplugs will also come in handy. Finally, find room for a few toiletry items to ensure you hop off the plane feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a Swiss Army knife hiding in your hand luggage. Other restricted items include explosive or flammable products, like aerosols and matches, and gels and liquids in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your top priority is to be as comfortable as possible. Go for slip-on footwear, dress in loose, breathable clothing and don't forget to bring a sweater in case you get cold in the cabin.
  • The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-distance flights. Lower your risks by staying hydrated, keeping your legs moving and wearing compression tights or socks.

How to get through airport security fast when flying to Kusatsu?
The answer is simple — be prepared. We've put together some tips and tricks for a fuss-free trip through security. Watch out Kusatsu, here you come:

  • Your boarding pass and passport will need to be presented to airport security personnel. Have them close by to avoid fumbling around for them.
  • The X-ray machine comes next. Empty your pockets and remove anything that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Your 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.
  • Can't travel without your favorite hand and nail cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, you can bring it with you in your carry-on luggage.
  • There's a possibility that you'll be asked to remove your shoes for scanning, so wearing lightweight sneakers is always a smart idea.
  • Sharp items like knives are not allowed in the cabin. They'll be seized at security, so pack them safely away in your checked bags.
