Cheap Flights to Puerto Iguazú from HK$2,497

If you're not prepared, air travel can be testing. But there's no need to worry. Follow these handy hints for a hassle-free start to your holiday in Puerto Iguazú. What to pack in your hand luggage:

• The secret to having an awesome flight experience is to be prepared. So, let's start with the basics: passport, boarding pass, cash and daily medications. Next, take on board items that'll help pass the time, like some electronic gadgets or a magazine. It's also smart to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. And of course, don't forget to pop in toiletries like a toothbrush, cleansing wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your Swiss Army knife, and dangerous goods which are explosive or flammable, such as aerosol cans, spray paint and poisons, are also not allowed.

What to wear on a flight:

• Comfort should be your main priority when choosing what to wear during your flight. Loose clothing is a sensible option, as are roomy, closed-toe shoes.
• Deep vein thrombosis (DVT) is a risk on long-haul flights. It's the result of blood clotting due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

As seasoned travellers know, the secret is to be prepared before you reach the security gate. That way, you'll be boarding that plane to Puerto Iguazú in no time flat. Follow these helpful tips and get your trip off to a great start:

• Security personnel first need to know that you have a valid passport and matching boarding pass before you can proceed any further. Keep them within easy reach.
• Next up, both you and your carry-on luggage must be X-rayed. To speed things up, take off anything that might trigger the alarms. Items such as your jacket, belt and headphones need to go through the machine.
• For just a few moments, you'll need to unplug from the digital world. Your laptop, phone and any other electronics will also need to go through the scanner.
• Any liquids or gels, such as shampoo or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
• Slip-on shoes are a great footwear choice as you're less likely to have to remove them when going through security. Big boots and other bulky shoes are often subjected to additional screening.
• Airlines will not allow any sharp items or pocket knives in your carry-on luggage. If you must bring these kinds of items, put them in your checked luggage.
