Cheap Flights to Boulogne from HK$6,485

We've got the lowdown on how to make your journey as stress-free as possible. Follow our top tips and you'll be hightailing it through airport security and enjoying Boulogne in no time at all.What to pack in your hand luggage:

• The secret to having a hassle-free travel experience is to be prepared. First up, the essentials: passport, boarding pass, cash and vital medications. Next, bring items that'll help keep you entertained, like some electronic gadgets or a few magazines. You'll also want to pack your chargers, a comfy neck pillow and a pair of earphones. Last but not least, be sure to pop in toiletry items like a toothbrush, lip balm and a spare set of clothes.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by security. Sharp objects, like your precious pocket knife, and products which are explosive or flammable, such as spray paint, flares and fuels, are also restricted.

What to wear on a flight:

• The best way to ensure a comfortable flight often lies in your choice of clothes. Prepare for temperature changes by bringing layers. This will keep you nice and warm if the cabin starts to cool down. Shoes like sandals and heels are best left in your suitcase. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will thank you later.
• Unfortunately, one risk of flying long-haul is developing deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity. To avoid this, make the most of every opportunity to walk around the cabin and stretch your legs. Compression socks and tights are another great idea to help minimize this risk.

Being prepared before you get to the airport can make your getaway to Boulogne a breeze. Here are some useful tips for a swift journey through security:

• Security personnel first need to make sure that you have a valid ID and travel documents before anything else. Have them ready to show.
• Time to strip down. Well sort of. Your belt, coat, keys and other small items, like coins, will be required to go through the X-ray machine. Make your life easier by removing them as your turn draws near.
• For just a few minutes, you'll have to unplug from technology. Your phone, tablet and any other electronics also need to go through the scanner.
• Can't travel without your favorite perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a clear zip-lock bag, it's OK to bring with you in your carry-on baggage.
• Lightweight sneakers are a great footwear choice as you're less likely to be required to remove them when going through security. Hiking boots and heavier-style shoes are usually subjected to additional screening.
• Sharp items are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked suitcase.
