We've pulled together all the info you need to make your journey a stress-free experience. Follow our insider tips and you'll be breezing through the airport and having a blast in Boulogne-sur-Mer before you know it. What to pack in your hand luggage:

• A plane ride can be a comfortable experience if you've got all the right gear. Firstly, you'll want a few basic toiletry items, such as a toothbrush and lip balm, a clean pair of socks and something to read. Secondly, leave space in your carry-on bag for your electronic devices, chargers, any vital medications and perhaps a comfy neck pillow too. Lastly, be sure to take your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp or pointed objects, like your beloved pocket knife, and products which are explosive or flammable, such as aerosol cans, flares and fuels, are also restricted.

What to wear on a flight:

• Your goal here is to feel as comfortable as possible. Opt for flat, closed-toe shoes, dress in loose, natural fibers and don't forget to take a pullover in case it gets chilly in the cabin.
• Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It's the result of blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.

It's all about being prepared. We've pulled together some handy tips and tricks for a speedy trip through security. Look out Boulogne-sur-Mer, here you come:

• Airport security personnel first need to determine that you have a valid ID and travel documents before you can proceed any further. Have them in your hand, ready for inspection.
• After that, both you and your carry-on bag will be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Personal belongings like your coat, belt and headphones need to go through the machine.
• For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronics will need to be sent through the scanner.
• Travelling with a new hand cream? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can keep it with you in your carry-on luggage.
• Choosing your footwear wisely can save you a few precious minutes. Boots are often required to be removed and separately scanned. Slip-on shoes usually aren't.
• Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed in the cabin.
