Cheap Flights to Porto Istana from HK$540

If you're not prepared, airports and flying can be challenging. But there's no need to worry. Follow these tips and tricks and enjoy a worry-free start to your getaway in Porto Istana. What to pack in your hand luggage:

• Firstly, and most importantly, put in your passport, travel docs, wallet and daily medications. Next, you'll want some in-flight entertainment to help pass the time. A thrilling novel and a laptop crammed with your favourite movies are some fantastic options. If you plan to take a short nap, a quality neck pillow and some noise-cancelling headphones will also come in handy. Finally, make room for a few toiletry items so you'll step off the plane looking fresh and ready to go.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of shampoo and conditioner in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like your pocket knife, and dangerous goods which are explosive or flammable, such as aerosol cans, spray paint and fuels, are also banned.

What to wear on a flight:

• Comfort should be your highest priority when deciding what to wear on board. Loose clothing is a smart option, as are flat, enclosed shoes.
• Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.

The answer is simple — be prepared. We've rounded up some useful tips for a speedy trip through security. Look out Porto Istana, here you come:

• Airport security personnel first need to see 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 carry-on bag will be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items like your coat, belt and earphones need to go through the machine.
• Electronic devices like laptops and phones will also need to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
• Travelling with a new hand cream? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you can keep it with you in your carry-on bag.
• The right choice of footwear can save you a few precious minutes. Boots are often required to be removed and separately scanned. Slip-on sneakers are usually not.
• Sharp items such as knives and scissors are not allowed on board. They'll be seized at security, so put them in your checked bags.
