Cheap Flights to Kumagawa from HK$399

We've rounded up all the info you need to make your journey as stress-free as possible. Follow our top tips and you'll be zooming through airport security and having a blast in Kumagawa in no time at all. What to pack in your hand luggage:

• It's easy — first, pack in your passport, official ID, cash and medications. Next, you'll want some entertainment to while away the hours. A juicy book and a tablet filled with your favourite movies are good options. If you hope to catch forty winks, a quality neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, make room for a toothbrush and some deodorant to ensure you touchdown feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your Swiss Army knife, and products which are explosive or flammable, such as aerosol cans, spray paint and poisons, are also banned.

What to wear on a flight:

• Go for comfort over style. Prepare for temperature changes by dressing in layers, and wear flat, easy-to-remove footwear like sneakers.
• Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.

Being organised before you get to the airport will make your getaway to Kumagawa a pleasure. Below are some useful tips for a swift journey past security:

• Security personnel first need to check that you have a valid passport and boarding pass before you're allowed to proceed any further. Keep them within easy reach.
• Next up, both you and your hand luggage must be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items like your belt, coat and earphones will be required to go through the machine.
• All electronic devices, including your phone and laptop, will also need to be scanned.
• Any gels or liquids, such as perfume or toothpaste, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
• Lightweight sneakers are a practical footwear choice as you're less likely to have to remove them when going through security. Big boots and other heavy shoes are usually subjected to additional screening.
• Sharp or pointed items can't be taken on board. They'll be seized at security, so pack them safely away in your checked bags.
