Depending on where you're coming from, your journey to Crolles could be as easy as pie or it could drag on forever. We've pulled together some handy travel tips that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:

• The secret to having a hassle-free travel experience is to be prepared. Start with the essentials: passport, travel documents, cash and any vital medications. Next, take on board items that'll help while away those hours, like some electronic devices or a juicy novel. It's also a wise idea to pack your chargers, a comfy neck pillow and a pair of headphones. And of course, don't forget to chuck in toiletry items like a toothbrush, facial wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

• While the list of banned items differs between air carriers, the general rule to follow is nothing flammable, sharp or explosive. This includes things like tools, metal cutlery, fuel and fireworks. Sports equipment like hockey sticks, and objects that could harm passengers, such as pepper spray and guns, aren't allowed in the cabin either.

What to wear on a flight:

• You'll want to choose comfort over style. Prepare for temperature changes in the cabin by layering up, and wear slightly roomy, flat footwear like sneakers.
• Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some gentle exercises in your seat to improve your circulation.

It's simple — be prepared. We've pulled together some useful tips for an easy trip through security. Look out Crolles, 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.
• Time to strip down. Well kind of. Your belt, coat, keys and other items in your pocket, like your earphones, will need to go through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn.
• All electronic devices, including your phone and laptop, must also be scanned.
• Any liquids or gels, such as toothpaste or perfume, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
• It's also possible you'll need to take your shoes off to be X-rayed, so wearing slip-on shoes is always a good idea.
• Airlines will not allow any sharp items or pocket knives in the cabin. If you need to bring these kinds of items, pack them in your checked luggage.
