Cheap Flights to Teresina from HK$4,038

If you're poorly prepared, airports and flying can be tough. But there's no need to worry. Follow these helpful hints and enjoy a worry-free start to your time in Teresina. What to pack in your hand luggage:

• A plane ride can be a great experience if you pack the right stuff. Firstly, you'll want some toiletry items, such as deodorant and a toothbrush, a spare pair of socks and a magazine or two. Secondly, leave space in your hand luggage for your mobile phone, a charger, medications and perhaps a cosy neck pillow as well. Lastly, be sure to bring your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

• While the list of banned items differs between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like tools, metal cutlery, fuels and bleaching agents. Sporting equipment like ski poles, and objects that could injure passengers, such as firearms and swords, are also banned from the cabin.

What to wear on a flight:

• Comfort should be your main priority when deciding what to wear during your flight. Loose, breathable clothing is a sensible choice, as are flat, slip-on shoes.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some simple exercises in your seat to promote better circulation.

It's all about being prepared. We've pulled together some useful tips for a stress-free trip through airport security. Look out Teresina, here you come:

• Be sure to keep your passport and boarding pass at hand. They'll be the first things you'll be asked for by airport security.
• After that, both you and your carry-on bag will be X-rayed. To make the process quick and painless, take off anything that might set the alarms off. Personal belongings such as your belt, coat and headphones need to go through the machine.
• All electronic gadgets, including your phone and tablet, are also required to be scanned separately.
• Remember to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag.
• Slip-on shoes are a good footwear choice as you're less likely to have to remove them when passing through security. Safety boots and heavier-style shoes are usually subjected to extra screening.
• Sharp items such as knives and scissors can't be taken on board. They'll be confiscated at security, so put them in your checked luggage.
