Cheap Flights to Porto Alegre from HK$8,569

Depending on where you're coming from, your trip to Porto Alegre could be completely stress-free or it could go on forever. We've rounded up some useful hints that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

• The trick to having a worry-free flight experience is to plan ahead. Start with the essentials: passport, boarding pass, cash and medications. Next, bring items that'll help pass the time, like some electronic gadgets or a good read. You'll also want to pack your chargers, a neck pillow and a pair of earplugs. Finally, don't forget to toss in toiletries like a toothbrush, cleansing wipes and a spare change of clothes.

Do not pack the following items in your hand luggage:

• Double-check that you don't have a sharp object lurking in one of the compartments of your hand luggage. Other banned items include flammable or explosive goods, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Choose comfort over style. Prepare for changes in temperature by donning layers, and wear closed-toe, flat footwear like slip-ons.
• Deep vein thrombosis (DVT) is a risk on long-distance flights. It results from blood clotting due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

Being organised before your flight can make your trip to Porto Alegre a breeze. Read through our handy tips for a speedy journey through security:

• Be sure to keep your travel documents and passport close by. They're the first items you'll be asked to present to airport security.
• The X-ray machine is up next. Empty your pockets and remove anything that is likely to set off the alarm. This includes things like headphones or earphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
• For just a few minutes, you'll need to unplug from technology. Your phone, laptop and any other electronics will need to be sent through the scanner.
• Want to bring along your favourite cologne or perfume? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can keep it with you in your carry-on luggage.
• There's a chance you'll be asked to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a smart idea.
• Sharp items such as knives and scissors are prohibited in the cabin. They'll be seized at security, so put them in your checked luggage.
