We've got the lowdown on how to make your journey as enjoyable as possible. Follow our top tips and you'll be hightailing it through the airport and having a blast in Saint-Louis before you know it. What to pack in your hand luggage:

• The trick to having a pain-free flight experience is to pack in advance. So, let's start with the essentials: passport, boarding pass, bank cards and important medications. Next, bring on board items that'll help keep you busy, like your laptop or a good read. It's also wise to pack your chargers, a quality neck pillow and a pair of noise-cancelling headphones. And of course, don't forget to pop in toiletries like a toothbrush, facial wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• While the list of restricted items can differ between air carriers, the general guide to follow is nothing sharp, flammable or explosive. This includes tools, metal cutlery, fuels and bleaching agents. Sporting equipment like baseball bats, and objects that could harm other people, such as pepper spray and guns, aren't allowed in the cabin either.

What to wear on a flight:

• The aisles of a plane aren't the place for a fashion parade. Wear layers and go for shoes that are closed-toe, flat and easy to pull on and off.
• Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy 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 improve your circulation.

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

• Your passport and travel documents will need to be presented to airport security personnel. Have them easily accessible to avoid fumbling around for them.
• The X-ray machine is up next. Remove anything metal on you that is likely to set off the scanner's alarm. This includes items 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 moments, you'll need to unplug from the digital world. Your tablet, phone and any other electronics will need to be sent through the scanner.
• Remove gels and liquids from your carry-on bag. They usually 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 single quart-size (one litre), clear zip-close bag.
• There's a possibility that you'll need to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a good idea.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed in the cabin.
