Cheap Flights to Helena from HK$6,549

If you're poorly prepared, travelling can be testing. But there's no need to hit the panic button just yet. Follow these useful tips for a hassle-free start to your time in Helena. What to pack in your hand luggage:

• The secret to having a worry-free flight experience is to be prepared. So, let's start with the essentials: passport, official ID, credit cards and any vital medications. Next, bring on board items that'll help keep you occupied, like your laptop or a magazine. You'll also want to bring your chargers, a quality neck pillow and a pair of earplugs. Finally, don't forget to toss in toiletry items like a toothbrush, cleansing wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Pointed or sharp objects, like your trusty Swiss Army knife, and products which are explosive or flammable, such as flares, chemicals agents and poisons, are also restricted.

What to wear on a flight:

• The aisles of an aircraft aren't the place for a fashion parade. Don comfortable layers and choose shoes that are flat, roomy and easy to remove.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some simple exercises in your seat to improve your circulation.

The simple answer is — be prepared. We've compiled some handy tips and tricks for a speedy trip through security. Watch out Helena, here you come:

• First things first. Your boarding pass and travel ID will need to be shown to airport security. Keep them within easy reach to avoid fumbling around for them.
• Next up, both you and your hand luggage must be X-rayed. To speed things up, take off anything that might trigger the alarms. Personal belongings like your belt, jacket and headphones will be required to go through the machine.
• All your electronics, including your laptop and phone, must also be scanned.
• Any gels or liquids, such as perfume or hand cream, 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 passing through security. Hiking boots and other heavy shoes are usually subjected to additional screening.
• Pocket knives and other sharp items are not allowed in the cabin. They'll be seized at security, so pack them in your checked luggage.
