Cheap Flights to Guadalix de la Sierra from HK$861

If you're not prepared, airports and flying can be a real challenge. But there's no need to panic. Follow these useful tips for a stress-free start to your time in Guadalix de la Sierra. What to pack in your hand luggage:

• First, pack your passport, official ID, wallet and daily medications. Next, you'll want some entertainment to while away the hours. A juicy novel and a phone filled with your favourite shows are always good options. If you hope to take a quick snooze, a quality neck pillow and some noise-cancelling headphones will also come in handy. Finally, find room for a toothbrush and some cleansing wipes to ensure you touchdown feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, drills, aerosol cans and bleaching agents. Sporting equipment like ski poles, and objects that could harm passengers, such as pepper spray and guns, can't come on board with you either.

What to wear on a flight:

• You'll want to go for comfort over style. Prepare for temperature changes by wearing layers, and opt for slightly roomy, flat shoes like sneakers.
• Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It results from blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

As seasoned travellers know, the secret is to be well prepared before you reach airport security. That way, you'll be stepping onto that plane to Guadalix de la Sierra before you know it. Follow these tips and get your trip off to a great start:

• Be sure to keep your ID and travel documents within close reach. They'll be the first things you'll be asked to present to security.
• After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Personal belongings such as your belt, coat and earphones need to go through the machine.
• All electronic gadgets, including your phone and tablet, must also be scanned.
• Remember to remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag.
• The right choice of footwear can save you several minutes. Hiking boots are often required to be removed and separately scanned. Lightweight sneakers are usually not.
• Airlines won't allow any sharp objects in your carry-on luggage. If you need to bring these kinds of items, pack them safely in your checked luggage.
