Cheap Flights to Caldas da Rainha from HK$297

Depending on where you're coming from, your trip to Caldas da Rainha could be a piece of cake or it could go on forever. Here are some useful travel tips that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:

• The trick to having a worry-free flight experience is to plan ahead. So, let's start with the basics: passport, boarding pass, credit cards and any vital medications. Next, take on board items that'll help keep you busy, like some electronic gadgets or a thrilling novel. It's also smart to bring your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. And of course, don't forget to toss in toiletry items like a toothbrush, cleansing wipes and a spare change of clothes.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes screwdrivers, drills, spray paint and flares. Sporting equipment like bows and arrows, and items that could harm other people, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

• The aisles of an airplane aren't the place for a fashion parade. Layer up with comfy clothing and opt for shoes that are roomy, flat and easy to slip on and off.
• Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It's the result of blood clots forming due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.

As savvy travellers know, the secret is to be well organised before you get to the security gate. That way, you'll be boarding that plane to Caldas da Rainha in next to no time. Follow these helpful tips and get your holiday off to a flying start:

• Airport security personnel first need to make sure that you have a valid ID and travel documents before you can proceed any further. Keep them close by.
• After that, both you and your carry-on bag will be X-rayed. To make the process quick and painless, take off anything that might trigger the alarms. Personal belongings like your belt, jacket 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 though, you'll be back online in no time.
• Any liquids or gels, such as lip balm or cologne, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must 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. Boots and other bulky shoes are often subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed on board and will be confiscated.
