Cheap Flights to Dorogawa Onsen from HK$709

Depending on where you're coming from, your trip to Dorogawa Onsen could be simple and straightforward or it could go on forever. We've rounded up some handy tips that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:

• Firstly, and most importantly, pack in your passport, official ID, wallet and daily medications. Next, you'll want some in-flight entertainment to help pass the time. A thrilling book and a phone crammed with your favourite shows are some fantastic options. If you intend to catch forty winks, a quality neck pillow and some earplugs will also be useful. Finally, find room for a few toiletry items to ensure you touchdown feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

• Put all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your trusty pocket knife, and dangerous products which are explosive or flammable, such as flares, bleaching agents and strong acids, are also restricted.

What to wear on a flight:

• Comfort should be your number one priority when choosing what to wear during your flight. Loose clothing is a wise option, as are flat, slip-on shoes.
• Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It results from blood clotting due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

A little pre-planning before your flight will make your trip to Dorogawa Onsen easy and painless. Check out our useful tips for a speedy journey through security:

• Security personnel first need to make sure that you have a valid passport and matching boarding pass before anything else. Have them close by, ready for inspection.
• After that, both you and your carry-on bag must be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Personal belongings such as your belt, coat and earphones need to go through the machine.
• All your electronic gadgets, including your phone and laptop, will also need to be scanned separately.
• Remove all liquids and gels from your carry-on bag. They often need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
• It's also possible you'll be asked to remove your shoes for scanning, so wearing slip-on shoes is always a clever idea.
• Airlines won't allow any pocket knives or other sharp items to come on board with you. If you must bring these kinds of items, pack them safely in your checked baggage.
