Cheap Flights to Entroncamento from HK$342

If you're poorly prepared, air travel can be tough. But there's no need to worry. Follow these handy hints and enjoy a trouble-free start to your holiday in Entroncamento. What to pack in your hand luggage:

• The trick to having a stress-free flight experience is to plan ahead. So, let's start with the essentials: passport, travel documents, credit cards and important medications. Next, take on board items that'll help keep you entertained, like some electronic devices or a magazine. It's also smart to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to toss in toiletry items like a toothbrush, deodorant and a spare set of clothes.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your precious pocket knife, and dangerous goods which are explosive or flammable, such as aerosol cans, spray paint and strong acids, are also restricted.

What to wear on a flight:

• The aisles of an aircraft aren't the place for a fashion parade. Wear layers and go for shoes that are flat, enclosed and easy to pull on and off.
• Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-distance flights. Reduce the risks by staying hydrated, keeping your ankles and legs moving and wearing compression tights or socks.

As savvy travellers know, the secret is to be well organised before you arrive at the airport security gate. That way, you'll be stepping onto that plane to Entroncamento in no time at all. Follow these tips and get your holiday off to a fantastic start:

• Keep your boarding pass and passport handy. They're the first things you'll be asked for by airport security.
• Your belt, coat, keys and other items in your pocket, like your headphones, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
• For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronic devices must also be sent through the scanner.
• Any gels or liquids, such as perfume or toothpaste, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
• The right choice of footwear can save you several valuable minutes. Boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
• Sharp or pointed objects (like knives and scissors) are not allowed in the cabin. They'll be seized at security, so pack them in your checked suitcase.
