Cheap Flights to Santillana del Mar from HK$4,425

If you're not prepared, airports and flying can be testing. But there's no need to worry. Follow these handy tips and enjoy a pain-free start to your getaway in Santillana del Mar. What to pack in your hand luggage:

• First and foremost, pack your passport, official ID, wallet and daily medications. Next, you'll want some in-flight entertainment to while away the hours. A juicy novel and a phone crammed with your favourite movies are some great options. If you plan to catch forty winks, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, leave space for a toothbrush and some cleansing wipes so you'll touchdown looking fresh and raring to go.

Do not pack the following items in your hand luggage:

• While the list of restricted items can differ between air carriers, the general rule of thumb is nothing flammable, sharp or explosive. This includes box cutters, razor blades, spray paint and flares. Sporting equipment like golf clubs, and objects that could harm other people, such as guns and swords, can't come on board with you either.

What to wear on a flight:

• Comfort should be your main concern when choosing what to wear on your flight. Loose, breathable clothing is a wise option, as are enclosed shoes like sneakers.
• Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to improve your circulation.

It's all about being prepared. We've put together some tips and tricks for an easy trip through airport security. Look out Santillana del Mar, here you come:

• Be sure to keep your boarding pass and passport within easy reach. They'll be the first things you'll be asked for by security.
• After that, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, take off anything that might set the alarms off. Personal belongings such as your coat, belt and headphones need to go through the machine.
• All your electronics, including your phone and tablet, will also need to be separately scanned.
• Any gels or liquids, such as lip balm or cologne, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
• Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when going through security. Hiking 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 and will be confiscated.
