We've got the lowdown on how to make your flight as stress-free as possible. Follow our insider tips and you'll be hightailing it through the airport and seeing the best of Rosny-sous-Bois in next to no time. What to pack in your hand luggage:

• The secret to having a pain-free travel experience is to be prepared. So, let's start with the basics: passport, travel docs, cash and daily medications. Next, bring items that'll help while away those hours, like some electronic gadgets or a few magazines. It's also a wise idea to bring your chargers, a neck pillow and a pair of earplugs. Finally, don't forget to chuck in toiletry items like a toothbrush, lip balm and a clean T-shirt.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes box cutters, razor blades, spray paint and fireworks. Sports equipment like baseball bats, and objects that could harm passengers, such as firearms and swords, aren't allowed in the cabin either.

What to wear on a flight:

• Go for comfort over style. Prepare for temperature changes in the cabin by dressing in layers, and wear closed-toe, flat footwear like sneakers.
• 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 gentle exercises in your seat to promote better circulation.

As seasoned travellers know, the secret is to be organised before you get to security. That way, you'll be boarding that plane to Rosny-sous-Bois in no time flat. Follow these helpful tips and get your trip off to a terrific start:

• Airport security personnel first need to know that you have a valid ID and boarding pass before you're allowed to proceed any further. Have them within easy reach, ready for inspection.
• After that, both you and your hand luggage must be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items such as your jacket, belt and headphones need to go through the machine.
• For just a few moments, you'll have to unplug from the digital world. Your tablet, phone and any other electronics will need to be sent through the scanner.
• Can't travel without your favourite hand and nail cream? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's OK to bring with you on board.
• Lightweight sneakers are a great footwear choice as you're less likely to be required to remove them when passing through security. Boots and heavier-style shoes are usually subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked luggage. They won't be allowed on board.
