We've got the lowdown on how to make your flight a stress-free experience. Follow our top tips and you'll be hightailing it through airport security and having a ball in Rosny-sur-Seine in no time at all. What to pack in your hand luggage:

• Travelling on a plane can be a comfortable experience if you've got all the right stuff. Firstly, you'll want some basic toiletry items, such as a toothbrush and hairbrush, a fresh change of clothes and a good read. Secondly, find room in your bag for your electronic devices, chargers, any vital medications and perhaps a comfy neck pillow too. Lastly, and most importantly, remember to bring your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

• Double-check that you don't have sharp objects (like a pocket knife) lurking in one of the zippers of your carry-on luggage. Other banned items include explosive or flammable products, such as fuel and fireworks, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• You'll want to choose comfort over style. Prepare for changes in temperature by donning layers, and pick easy-to-remove footwear like slip-ons.
• Most of us have heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To minimize your risk on board, drink plenty of water, consider wearing compression socks or tights and move your lower limbs often.

A little pre-planning before you get to the airport will help make your getaway to Rosny-sur-Seine quick and painless. Below you'll find some top tips for a swift journey past security:

• Security personnel first need to establish that you have a valid ID and boarding pass before you can proceed any further. Have them ready to show.
• The X-ray machine comes next. Remove anything metal on you that is likely to beep. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
• For just a few minutes, you'll have to unplug from technology. Your phone, laptop and any other electronic gadgets must also go through the scanner.
• Any liquids or gels, such as perfume or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
• Lightweight sneakers are a good footwear choice as you're less likely to have to remove them when going through security. Safety boots and heavier-style shoes are usually subjected to additional screening.
• Airlines will not allow any pocket knives or other sharp items in your carry-on baggage. If you need to bring these kinds of items, pack them in your checked luggage.
