If you're not prepared, travelling can be challenging. But there's no need to hit the panic button just yet. Follow these helpful hints and enjoy a trouble-free start to your getaway in Tonga. What to pack in your hand luggage:

• The secret to having a pain-free flight experience is to pack ahead. Start with the essentials: passport, travel docs, credit cards and any vital medications. Next, bring on board items that'll help while away those hours, like your laptop or a good book. It's also wise to bring your chargers, a comfy neck pillow and a pair of earphones. Last but not least, don't forget to toss 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 restricted items can differ between air carriers, the general rule of thumb is nothing flammable, sharp or explosive. This includes screwdrivers, drills, spray paint and flares. Sports equipment like baseball bats, and objects that could harm other people, such as pepper spray and firearms, won't be allowed on board either.

What to wear on a flight:

• Your top priority is to feel as comfortable as possible. Go for shoes that are easy to pull on and off, dress in loose, breathable clothing and remember to bring a jacket in case it gets cold in the cabin.
• Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some gentle exercises in your seat to promote better circulation.

The secret is to be organised before you reach security. That way, you'll be hopping onto that plane to Tonga before you know it. Follow these helpful tips and get your trip off to a terrific start:

• Have your travel documents and ID within close reach. They'll be the first things you'll be asked for by security.
• The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
• Your electronic gadgets like phones and laptops will also have to go on a tray to be scanned. 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 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.
• It's also possible you'll be asked to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a clever idea.
• Airlines will not allow any pocket knives or other sharp items in your carry-on baggage. If you must bring these kinds of items, pack them in your checked baggage.
