Cheap Flights to Tres Cantos from HK$2,639

Wherever you're jetting in from, flying can be a seamless experience if you prepare well enough. Take a peek at these handy hints that will get your Tres Cantos holiday started on the right foot. What to pack in your hand luggage:

• Firstly, and most importantly, pack in your passport, official ID, wallet and medications. Next, you'll need some in-flight entertainment to while away the hours. A thrilling novel and a laptop filled with your favourite shows are some wonderful options. If you hope to catch up on some sleep, a neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, leave space for a toothbrush and some facial wipes so you'll arrive looking fresh and raring to go.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between airlines, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes knives, scissors, spray paint and flares. Sports equipment like baseball bats, and objects that could harm passengers, such as pepper spray and guns, are also banned from the cabin.

What to wear on a flight:

• Go for comfort over style. Prepare for temperature changes by layering up, and opt for easy-to-remove shoes like sneakers.
• Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clotting due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

Being prepared before your flight can make your getaway to Tres Cantos a breeze. Below are some handy tips for a speedy journey past security:

• Keep your ID and travel documents within easy reach. They're the first items you'll be asked to present to security.
• The X-ray machine is up next. Remove anything metal on you that is likely to beep. This includes things like earphones or headphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
• All your electronic gadgets, including your tablet and phone, will also need to be scanned separately.
• Any liquids or gels, such as toothpaste or perfume, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
• Lightweight sneakers are a practical footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and other bulky shoes are usually subjected to additional screening.
• Airlines will not allow any pocket knives or other sharp items in your carry-on baggage. If you need to bring these kinds of items, put them in your checked baggage.
