Cheap Flights to Iruka Onsen from HK$655

Depending on where you're coming from, your flight to Iruka Onsen could be a breeze or it could go on forever. Here are some tips that will help you start your unforgettable escape on the right foot. What to pack in your hand luggage:

• A plane trip can be a comfortable experience if you carry the right stuff. First things first, you'll need basic toiletry items, such as lip balm and hand cream, a spare change of clothes and something to read. Next, make room in your carry-on bag for your electronic devices, chargers, medications and maybe a cosy neck pillow too. Lastly, and most importantly, remember to take your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

• While the list of banned items differs between airlines, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like knives, scissors, spray paint and flares. Sports equipment like bows and arrows, and objects that could harm other people, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

• The aisles of an airplane are no place for a fashion parade. Dress in comfortable layers and choose shoes that are flat and easy to remove.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some gentle exercises in your seat to promote better circulation.

It's easy — be prepared. We've rounded up some handy tips and tricks for a fuss-free trip through security. Look out Iruka Onsen, here you come:

• Airport security personnel first need to establish that you have a valid passport and matching travel documents before you can proceed any further. Have them ready to show.
• The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
• 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 gels or liquids, such as lip balm or cologne, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
• There's a chance you'll be asked to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a clever idea.
• Airlines will not allow any sharp objects in the cabin. If you need to bring these kinds of items, pack them safely in your checked baggage.
