Cheap Flights to Crecy-sur-Serre from HK$2,617

If you're poorly prepared, air travel can be testing. But don't hit the panic button just yet. Follow these handy tips for a trouble-free start to your holiday in Crecy-sur-Serre. What to pack in your hand luggage:

• The secret to having a hassle-free travel experience is to pack ahead. So, let's start with the essentials: passport, travel docs, cash and medications. Next, bring items that'll help pass the time, like some electronic devices or a magazine. It's also smart to pack your chargers, a neck pillow and a pair of earphones. Finally, don't forget to squeeze in toiletries like a toothbrush, cleansing wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your precious 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:

• The aisles of an aircraft are no place for a fashion parade. Layer up with comfortable clothing and choose shoes that are flat, roomy and easy to pull on and off.
• Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to improve your circulation.

Being organised before you arrive at the airport will help make your getaway to Crecy-sur-Serre a piece of cake. We've rounded up some handy tips for a speedy journey past security:

• Airport security personnel first need to know that you have a valid ID and travel documents before you can proceed any further. Have them ready to show.
• After that, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Personal belongings like your belt, coat and headphones will be required to go through the machine.
• For just a few moments, you'll have to unplug from the digital world. Your laptop, phone and any other electronic devices will need to be sent through the scanner.
• Remember to remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
• There's a chance you'll be required to remove your shoes for scanning, so wearing slip-on sneakers is always a wise idea.
• Sharp or pointed items are not allowed in the cabin. They'll be confiscated at security, so put them in your checked baggage.
