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

• The secret to having a great flight experience is to pack in advance. So, let's start with the basics: passport, official ID, credit cards and any vital medications. Next, bring on board items that'll help keep you entertained, like some electronic gadgets or a good read. It's also wise to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, be sure to pop in toiletry items like a toothbrush, cleansing wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

• Put all your full-sized bottles of shampoo and hairspray in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your pocket knife, and dangerous goods which are flammable or explosive, such as spray paint, flares and strong acids, are also restricted.

What to wear on a flight:

• Choose comfort over style. Prepare for temperature changes in the cabin by layering up, and wear easy-to-remove shoes like sneakers.
• Deep vein thrombosis (DVT) is a risk on long-haul flights. It's the result of blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

It's all about being prepared. We've compiled some helpful hints for a stress-free trip through airport security. Look out O'Leary, here you come:

• Your passport and boarding pass will need to be presented to airport security. Keep them within easy reach to avoid fumbling around for them.
• Your coat, belt, keys and other contents of your pockets, like your headphones, will need to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
• For just a few moments, you'll have to unplug from the digital world. Your laptop, phone and any other electronics must also be sent through the scanner.
• Remove all liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
• Choosing your footwear wisely can save you several minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on sneakers are usually not.
• Airlines won't allow any sharp objects to come on board with you. If you need to bring these kinds of items, put them in your checked baggage.
