We've pulled together all the info you need to make your journey a stress-free experience. Follow our tips and you'll be hightailing it through airport security and enjoying San Luis in no time at all. What to pack in your hand luggage:

• A plane trip can be a pleasure if you've got all the right things. First things first, you'll need basic toiletries, such as lip balm and hand cream, a clean set of clothes and a few magazines. Next, find a spot in your bag for your phone and charger, your medications and perhaps a proper neck pillow too. Lastly, don't forget to bring your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

• While the list of restricted items differs between airlines, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes things like screwdrivers, pocket knives, fireworks and fuel. Sporting equipment like baseball bats, and objects that could harm passengers, such as firearms and swords, won't be allowed on board either.

What to wear on a flight:

• Your goal here is to be as comfortable as you can. Opt for easy-to-remove footwear, dress in loose, natural fibers and don't forget to bring a jacket in case it gets cold in the cabin.
• Most travellers are aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To lessen your risk on board, drink lots of water, consider wearing compression socks and move your legs and feet often.

The trick is to be prepared before you get to the security gate. That way, you'll be hopping onto that plane to San Luis in next to no time. Follow these helpful tips and get your trip off to a great start:

• Keep your boarding pass and passport someplace easily accessible. They're the first things you'll be asked to show at airport security.
• Next up, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Items like your belt, jacket and headphones need to go through the machine.
• All your electronics, including your laptop and phone, are also required to be scanned.
• Remove all gels and liquids from your hand luggage. They often need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-close bag.
• There's a good chance you'll be required to remove your shoes to be X-rayed, so wearing slip-on shoes is always a smart idea.
• Airlines will not allow any sharp items or pocket knives in your carry-on luggage. If you must bring these kinds of items, put them in your checked baggage.
