We've rounded up all the info you need to make your flight as pain-free as possible. Follow our insider tips and you'll be breezing through airport security and having a blast in Nezahualcóyotl in next to no time. What to pack in your hand luggage:

• The secret to having a worry-free travel experience is to plan ahead. First up, the essentials: passport, official ID, credit cards and medications. Next, take on board items that'll help keep you busy, like some electronic gadgets or a few magazines. It's also wise to pack your chargers, a quality neck pillow and a pair of earplugs. Last but not least, don't forget to squeeze in toiletry items like a toothbrush, deodorant and a clean set of clothes.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your precious Swiss Army knife, and products which are explosive or flammable, such as aerosols and poisons, are also prohibited.

What to wear on a flight:

• The aisles of a plane aren't the place for a fashion parade. Layer up with comfortable clothing and go for shoes that are closed-toe, flat and easy to slip on and off.
• Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clotting due to poor circulation and inactivity, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

It's easy — be prepared. We've rounded up some tips and tricks for a hassle-free trip through airport security. Watch out Nezahualcóyotl, here you come:

• Airport security personnel first need to check that you have a valid ID and boarding pass before you're allowed to proceed any further. Keep them close by.
• Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the 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.
• All your electronics, including your tablet and phone, must also be scanned.
• Travelling with a new hand cream? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's OK to bring with you in your carry-on luggage.
• Slip-on shoes are a great footwear choice as you're less likely to have to remove them when passing through security. Safety boots and other bulky shoes are often subjected to additional screening.
• Airlines won't allow any pocket knives or other sharp items in your carry-on baggage. If you must bring these kinds of items, check them in.
