Cheap Flights to St. Johnsbury from HK$1,551

If you're not prepared, traveling can be tough. But there's no need to panic. Follow these tips and tricks for a pleasant start to your getaway in St. Johnsbury.What to pack in your hand luggage:

• The secret to having an amazing travel experience is to plan ahead. So, let's start with the essentials: passport, travel documents, cash and vital medications. Next, bring items that'll help while away those hours, like some electronic gadgets or a good read. It's also a wise idea to bring your chargers, a quality neck pillow and a pair of noise-canceling headphones. And of course, be sure to toss in toiletries like a toothbrush, lip balm and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Pointed or sharp objects, like your beloved pocket knife, and products which are explosive or flammable, such as aerosol cans, flares and strong acids, are also prohibited.

What to wear on a flight:

• The aisles of an aircraft are not the place for a fashion parade. Layer up with comfy clothing and bring a sweater as it can get chilly inside the cabin on long-haul flights. Flat, slightly roomy shoes are also a sensible choice.
• Caused by sustained periods of immobility, DVT (deep vein thrombosis) is a blood clot condition that can affect some passengers during long-haul flights. But the good news is there are numerous ways to reduce the risk of developing it. Stay well hydrated, get up and wander the aisles as much as you can and wear compression socks to help improve your circulation.

The simple answer is — be prepared. We've rounded up some useful tips for a fuss-free trip through airport security. Watch out St. Johnsbury, here you come:

• First things first. Your travel ID and boarding pass will need to be presented to security personnel. Keep them handy so you don't hold up the line.
• Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to beep. This includes items like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
• Electronic devices like laptops and phones will also need to go on a tray for inspection. Don't worry, you'll be back online soon enough.
• Remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-lock bag.
• It's also likely that you'll need to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a smart idea.
• Sharp items like knives can't be taken on board. They'll be seized at security, so put them in your checked luggage.
