Cheap Flights to Sintra from CA $422

Depending on where you're coming from, your flight to Sintra could be a breeze or it could go on forever. We've rounded up some useful hints that will help you start your next big adventure on the right foot. What to pack in your hand luggage:

• First of all, pack your passport, travel documents, wallet and vital medications. Next, you'll need some entertainment to while away the time. A juicy book and a phone filled with your favourite movies are some terrific options. If you plan to take a short snooze, a neck pillow and a pair of earplugs will also come in handy. Finally, leave space for a toothbrush and some deodorant to ensure you arrive at your destination looking and feeling fresh.

Do not pack the following items in your hand luggage:

• While the list of banned items can differ between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like screwdrivers, drills, fireworks and fuel. Sports equipment like ice skates, and items that could harm other people, such as firearms and swords, won't be allowed on board either.

What to wear on a flight:

• Your priority is to be as comfortable as possible. Go for shoes that are easy to slip on and off, dress in loose, natural fibers and remember to bring a sweater in case you get cold in the cabin.
• Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of 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.

Being organized before you get to the airport will make your trip to Sintra quick and painless. Below are some useful tips for a swift journey through security:

• Keep your boarding pass and passport easily accessible. They're the first items you'll be asked for by airport security.
• Your coat, belt, keys and other items in your pocket, like your headphones, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
• All your electronic devices, including your laptop and phone, will also need to be scanned.
• Remove gels and liquids from your hand luggage. They often need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
• Lightweight sneakers are a clever footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and heavier-style shoes are often subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed on board and will be confiscated.
