We've pulled together all the info you need to make your journey an enjoyable experience. Follow our insider tips and you'll be cruising through airport security and enjoying Boulogne-Billancourt in no time. What to pack in your hand luggage:

• A plane trip can be a great experience if you pack the right gear. First of all you'll need basic toiletries, such as deodorant and a toothbrush, a clean pair of socks and a good read. Secondly, find a spot in your hand luggage for your electronic gadgets, chargers, your important medications and maybe a proper neck pillow as well. Lastly, don't forget to bring your passport, travel papers and your bank cards.

Do not pack the following items in your hand luggage:

• Leave 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 by authorities. Sharp or pointed objects, like your trusty pocket knife, and dangerous goods which are explosive or flammable, such as aerosol cans, spray paint and gasoline, are also restricted.

What to wear on a flight:

• Go for comfort over style. Prepare for changes in temperature by donning layers, and pick flat, slightly roomy footwear like sneakers.
• The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-distance flights. Reduce the risks by staying hydrated, keeping your lower limbs moving and wearing compression socks or tights.

It's all about being organised. We've put together some useful tips for an easy trip through security. Watch out Boulogne-Billancourt, here you come:

• Security personnel first need to know that you have a valid passport and matching boarding pass before you're allowed to proceed any further. Have them ready for inspection.
• Next up is the X-ray machine. Empty your pockets and remove anything that is likely to beep. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
• All your electronics, including your phone and tablet, will also need to be scanned separately.
• Any gels or liquids, such as shampoo or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
• It's also likely that you'll be required to remove your shoes for scanning, so wearing slip-on sneakers is always a clever idea.
• Airlines won't allow any pocket knives or other sharp items in your hand luggage. If you need to bring these kinds of items, put them in your checked luggage.
