How to survive the flight to Siem Reap?
We’ve rounded up all the info you need to make your flight an enjoyable experience. Follow our top tips and you’ll be breezing through the airport and enjoying Siem Reap in no time at all.What to pack in your hand luggage:

  • The secret to having a worry-free flight experience is to pack in advance. So, let’s start with the essentials: passport, boarding pass, credit cards and daily medications. Next, bring on board items that’ll help keep you occupied, like some electronic gadgets or a magazine. It’s also smart to pack your chargers, a neck pillow and a pair of headphones. Finally, don’t forget to squeeze in toiletry items like a toothbrush, facial wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by security. Sharp objects, like your trusty Swiss Army knife, and products which are flammable or explosive, such as aerosol cans, flares and matches, are also restricted.

What to wear on a flight:

  • The long, narrow aisles of your plane are not the place for a fashion parade. Layer up with comfortable clothing and pack a sweater as it can get chilly inside the cabin on long-haul flights. Flat, slightly roomy shoes are also a wise idea.
  • Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a serious condition that can affect passengers on long-distance flights. The great news is there are ways to significantly reduce the risk of developing it. Stay well hydrated, get up and wander the aisles as much as you can and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to Siem Reap?
It’s all about being organised. We’ve compiled some tips and tricks for a stress-free trip through security. Watch out Siem Reap, here you come:

  • Be sure to keep your travel documents and ID someplace easily accessible. They’re the first items you’ll be asked for by airport security.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to beep. This includes items like headphones or earphones, as well as bulky coats or jackets. They’ll all need to go on the X-ray conveyor belt.
  • Your electronic gadgets like laptops and phones will also have to go through the machine for inspection. No need to worry though, you’ll be back online soon enough.
  • Remember to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • There’s a chance you’ll be asked to remove your shoes to be X-rayed, so wearing slip-on shoes is always a wise idea.
  • Airlines won’t allow any pocket knives or other sharp items in your carry-on luggage. If you need to bring these kinds of items, pack them in your checked baggage.
