Cheap Flights to Tonga from HK$1,281

No matter where you're coming from, flying can be an enjoyable experience if you're well prepared. We've put together a list of handy hints that will get your Tonga escape started on the right foot. What to pack in your hand luggage:

• The trick to having a worry-free flight experience is to be prepared. Start with the essentials: passport, boarding pass, cash and medications. Next, bring on board items that'll help keep you occupied, like some electronic devices or a good book. You'll also want to bring your chargers, a neck pillow and a pair of earphones. And of course, be sure to squeeze in toiletries like a toothbrush, lip balm and a clean 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 tools, metal cutlery, fuel and fireworks. Sporting equipment like bows and arrows, and items that could harm other people, such as firearms and swords, won't be allowed on board either.

What to wear on a flight:

• Your aim here is to feel as comfortable as you can. Choose flat, closed-toe shoes, dress in loose, natural-fibre clothing and remember to bring a jacket in case it gets chilly in the cabin.
• Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some gentle exercises in your seat to promote better circulation.

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

• Your travel documents and passport will need to be inspected by security personnel. Keep them someplace accessible to avoid fumbling around for them.
• Time to strip down. Well sort of. Your belt, jacket, keys and other small items, like coins, will be required to go through the X-ray machine. Make your life easier by removing them before your turn.
• Your electronic devices like phones and laptops will also have to go through the machine for inspection. No need to worry though, you'll be back online before you know it.
• Remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-close bag.
• The right choice of footwear can save you a few precious minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on shoes are usually not.
• Airlines will not allow any sharp objects in your carry-on luggage. If you must bring these kinds of items, put them in your checked baggage.
