• A plane ride can be easy if you take the right stuff. Firstly, you'll want some basic toiletry items, such as deodorant, toothpaste and a toothbrush, a clean set of clothes and a magazine or two. Secondly, find a spot in your bag for your electronic gadgets, chargers, your medications and maybe a cosy neck pillow too. Lastly, and most importantly, don't forget to take your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

• Double-check that you don't have a sharp object hiding in your hand luggage. Other restricted items include explosive or flammable products, such as aerosol cans and bleach, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• You'll want to go for comfort over style. Prepare for changes in cabin temperature by layering up, and pick flat, easy-to-remove shoes like sneakers.
• Most of us have heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To minimize your risk on board, drink lots of water, consider wearing compression socks and keep your legs and feet moving.

The answer is — be prepared. We've compiled some top tips for an easy trip through security. Watch out Sao Sebastiao do Cai, here you come:

• Security personnel first need to see that you have a valid ID and travel documents before you're allowed to proceed any further. Keep them close by.
• Next up, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Personal belongings such as your belt, coat and headphones need to go through the machine.
• All your electronic devices, including your laptop and phone, must also be scanned separately.
• Remove all liquids and gels from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
• Slip-on shoes are a great footwear choice as you're less likely to have to remove them when going through security. Big boots and other heavy shoes are often subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked suitcase. They won't be allowed on board and will be confiscated.
