We've pulled together all the info you need to make your flight as pain-free as possible. Follow our tips and tricks and you'll be speeding through airport security and exploring Sânmartin before you know it. What to pack in your hand luggage:

• The secret to having an awesome travel experience is to plan ahead. First up, the essentials: passport, boarding pass, cash and important medications. Next, bring items that'll help keep you entertained, like some electronic gadgets or a juicy novel. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of earphones. And of course, don't forget to chuck in toiletry items like a toothbrush, cleansing wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like a Swiss Army knife, and dangerous products which are flammable or explosive, such as spray paint, flares and strong acids, are also not allowed.

What to wear on a flight:

• Your aim is to feel as comfortable as you can. Choose slip-on footwear, dress in loose, natural fibers and don't forget to bring a sweater in case it gets chilly in the cabin.
• Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to promote better circulation.

The simple answer is — be prepared. We've compiled some useful tips for a hassle-free trip through security. Watch out Sânmartin, here you come:

• Airport security personnel first need to check that you have a valid passport and matching boarding pass before you can proceed any further. Have them in your hand, ready for inspection.
• Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
• For just a few minutes, you'll have to unplug from technology. Your phone, laptop and any other electronics will also need to go through the scanner.
• Any liquids or gels, such as shampoo or hairspray, 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-lock bag.
• It's also possible you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a wise idea.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked baggage. They won't be allowed on board.
