Cheap Flights to Viana do Castelo from HK$234

We've got the lowdown on how to make your flight an enjoyable experience. Follow our insider tips and you'll be zooming through the airport and exploring Viana do Castelo in no time at all. What to pack in your hand luggage:

• Firstly, and most importantly, pack in your passport, travel documents, bank cards and vital medications. Next, you'll need some in-flight entertainment to while away the hours. A juicy novel and a phone filled with your favourite movies are some fantastic options. If you intend 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 to ensure you arrive at your destination looking fresh and ready to go.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and hair gel in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like your precious Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, bleaching agents and fireworks, are also restricted.

What to wear on a flight:

• Choose comfort over style. Prepare for temperature changes by wearing layers, and opt for flat, closed-toe footwear like slip-ons.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some gentle exercises in your seat to promote better circulation.

The simple answer is — be prepared. We've rounded up some helpful hints for a hassle-free trip through security. Watch out Viana do Castelo, here you come:

• Airport security personnel first need to verify that you have a valid ID and boarding pass before you can proceed any further. Have them close by, ready for inspection.
• After that, both you and your hand luggage must be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Personal belongings like your belt, coat and earphones will be required to go through the machine.
• For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronic gadgets must also go through the scanner.
• Any gels or liquids, such as shampoo or hairspray, 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), zip-lock bag.
• Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when passing through security. Safety boots and heavier-style shoes are usually subjected to additional screening.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked baggage. They won't be allowed on board.
