Cheap Flights to Helena from HK$4,633

If you're not prepared, travelling can be overwhelming. But there's no need to worry. Follow these handy tips and enjoy a stress-free start to your time in Helena. What to pack in your hand luggage:

• The trick to having a stress-free flight experience is to be prepared. So, let's start with the essentials: passport, travel docs, credit cards and vital medications. Next, take on board items that'll help while away those hours, like your laptop or a thrilling book. You'll also want to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, be sure to pop in toiletry items like a toothbrush, deodorant and a spare change of clothes.

Do not pack the following items in your hand luggage:

• Double-check that you don't have sharp objects (like a knife or scissors) lurking in the bottom of your hand luggage. Other prohibited items include flammable or explosive goods, such as aerosol cans and fuel, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Your aim here is to feel as comfortable as possible. Pick easy-to-remove footwear, dress in loose, breathable clothing and don't forget to take a pullover in case you get chilly in the cabin.
• Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-haul flights. Lower your risks by drinking water, keeping your ankles and legs moving and wearing compression tights or socks.

It's simple — be prepared. We've put together some top tips for a speedy trip through security. Look out Helena, here you come:

• Have your boarding pass and passport close by. They're the first things you'll be asked to present to security.
• Time to strip down. Well kind of. Your belt, jacket, keys and other contents of your pockets, like coins, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
• All your electronic devices, including your phone and laptop, are also required to be scanned separately.
• Any liquids or gels, such as shampoo or hand cream, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
• Choosing your footwear wisely can save you several valuable minutes. Boots are often required to be removed and separately scanned. Lightweight sneakers are usually not.
• Sharp items can't be taken on board. They'll be confiscated at security, so pack them in your checked luggage.
