Cheap Flights to Sao Caetano do Sul from HK$1,431

If you're poorly prepared, airports and flying can be overwhelming. But there's no need to worry. Follow these useful tips and enjoy a hassle-free start to your holiday in Sao Caetano do Sul. What to pack in your hand luggage:

• The trick to having a stress-free travel experience is to pack ahead. So, let's start with the basics: passport, official ID, credit cards and important medications. Next, bring on board items that'll help while away those hours, like your laptop or a thrilling novel. It's also smart to pack your chargers, a quality neck pillow and a pair of earphones. Last but not least, don't forget to squeeze in toiletry items like a toothbrush, cleansing wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between airlines, the general rule to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, knives, spray paint and fireworks. Sports equipment like golf clubs, and items that could harm passengers, such as firearms and swords, can't come on board with you either.

What to wear on a flight:

• Your goal here is to be as comfortable as possible. Choose a pair of flat, closed-toe shoes, dress in loose, natural fibers and remember to bring a sweater in case you get cold in the cabin.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to promote better circulation.

The secret is to be prepared before you reach security. That way, you'll be stepping onto that plane to Sao Caetano do Sul in no time flat. Follow these tips and get your holiday off to a fantastic start:

• First things first. Your passport and boarding pass will need to be presented to airport security. Keep them handy so you don't hold up the queue.
• Next up, both you and your hand luggage must be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Personal belongings such as your jacket, belt and earphones will be required to go through the machine.
• For just a few minutes, you'll need to unplug from technology. Your phone, laptop and any other electronics will also need to go through the scanner.
• Any liquids or gels, such as perfume or toothpaste, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
• It's also likely that you'll need to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a clever idea.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed in the cabin.
