We've pulled together all the info you need to make your flight as pain-free as possible. Follow our insider tips and you'll be cruising through the airport and having a blast in Sihanoukville in no time. What to pack in your hand luggage:

• The trick to having an awesome travel experience is to pack in advance. First up, the essentials: passport, official ID, cash and medications. Next, bring items that'll help while away those hours, like your laptop or a thrilling novel. It's also a wise idea to bring your chargers, a quality neck pillow and a pair of earplugs. Last but not least, be sure to pop in toiletry items like a toothbrush, deodorant and a clean T-shirt.

Do not pack the following items in your hand luggage:

• Make sure you don't have sharp objects (like a pocket knife) hiding in the bottom of your carry-on luggage. Other restricted items include explosive or flammable products, such as fuel and fireworks, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• You'll want to go for comfort over style. Prepare for changes in temperature by donning layers, and opt for flat, slightly roomy footwear like slip-ons.
• Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-haul flights. Reduce the risks by drinking water, keeping your ankles and legs moving and wearing compression socks to help your circulation.

Being organised before your flight can make your getaway to Sihanoukville quick and painless. Read through our handy tips and tricks for a stress-free journey through security:

• First things first. Your ID and travel documents will need to be shown to airport security personnel. Keep them within easy reach so you don't hold up the line.
• Time to strip down. Well sort of. Your jacket, belt, keys and other contents of your pockets, like coins, will need to go on a tray through the X-ray machine. Make your life easier by removing them before your turn arrives.
• Electronic devices like phones and laptops will also need to go on a tray to be scanned. Don't worry, you'll be back online in no time.
• Any gels or liquids, such as perfume or hairspray, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
• Slip-on shoes are a good footwear choice as you're less likely to be required to remove them when passing through security. Boots and other bulky shoes are often subjected to extra screening.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won't be allowed in the cabin.
