Cheap Flights to Buenos Aires from HK$1,663

If you're poorly prepared, air travel can be testing. But there's no need to worry. Follow these handy hints for a worry-free start to your getaway in Buenos Aires. What to pack in your hand luggage:

• The trick to having an amazing travel experience is to plan ahead. So, let's start with the essentials: passport, travel documents, credit cards and daily medications. Next, take on board items that'll help keep you occupied, like your laptop or a magazine. It's also a wise idea to pack 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, deodorant and a spare set of clothes.

Do not pack the following items in your hand luggage:

• Put all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your beloved pocket knife, and dangerous products which are explosive or flammable, such as aerosol cans, spray paint and strong acids, are also not allowed.

What to wear on a flight:

• The aisles of an aircraft aren't the place for a fashion parade. Dress in comfortable layers and go for shoes that are roomy, flat and easy to pull on and off.
• Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of 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 improve your circulation.

As seasoned travellers know, the secret is to be prepared before you get to airport security. That way, you'll be hopping onto that plane to Buenos Aires in the blink of an eye. Follow these tips and get your trip off to a fantastic start:

• Security personnel first need to check that you have a valid passport and matching boarding pass before you're allowed to proceed any further. Keep them within easy reach.
• After that, both you and your hand luggage must be X-rayed. To speed things up, remove anything that might trigger the alarms. Items like your belt, jacket and headphones need to go through the machine.
• For just a few minutes, you'll need to unplug from technology. Your phone, tablet and any other electronic devices must also go through the scanner.
• Any liquids or gels, such as lip balm or cologne, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
• Lightweight sneakers are a great footwear choice as you're less likely to be asked to remove them when going through security. Safety boots and other bulky shoes are usually subjected to extra screening.
• Sharp items are not allowed on board. They'll be confiscated at security, so put them in your checked suitcase.
