Cheap Flights to Olen from HK$477

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

• The secret to having a pain-free flight experience is to be prepared. Start with the essentials: passport, travel documents, credit cards and important medications. Next, take on board items that'll help while away those hours, like your laptop or a juicy novel. It's also a wise idea to pack your chargers, a comfy neck pillow and a pair of headphones. And of course, don't forget to squeeze in toiletries like a toothbrush, deodorant and a spare set of clothes.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between air carriers, the general guide to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, knives, fuel and fireworks. Sports equipment like ski poles, and items that could harm other people, such as firearms and swords, aren't allowed in the cabin either.

What to wear on a flight:

• Go for comfort over style. Prepare for changes in temperature by dressing in layers, and wear easy-to-remove shoes like sneakers.
• Deep vein thrombosis (DVT) is a risk on long-haul flights. It's the result of blood clots forming due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

The answer is simple — be prepared. We've compiled some top tips for a hassle-free trip through airport security. Look out Olen, here you come:

• Your boarding pass and travel ID will need to be shown to airport security personnel. Keep them at hand so you don't have to dig around for them.
• The X-ray machine comes next. Remove anything on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
• All your electronic gadgets, including your laptop and phone, must also be scanned separately.
• Any gels or liquids, such as lip balm or cologne, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
• Slip-on shoes are a clever footwear choice as you're less likely to be asked to remove them when going through security. Boots and other bulky shoes are often subjected to extra screening.
• Knives and other sharp items are prohibited in the cabin. They'll be seized at security, so put them in your checked suitcase.
