Frequently asked questions

How to book the cheapest flight to Siem Reap?
If you'd like to have some extra spending money on your trip to Siem Reap, then listen up! As any experienced traveller knows, don't leave booking until the last minute. Prices are often highest just prior to the departure date. Also, shop around and compare your options. If your destination has more than one airport, you may be able to nab a great deal by flying into a less busy terminal. Last but not least, be ready to lock in your seat quickly if you stumble on a real bargain. It might not be available for too long. With a bit of know-how and a little good fortune, the ideal airfare will be yours.
Do you have any tips for my flight to Siem Reap?
We've rounded up all the info you need to make your journey as pain-free as possible. Follow our tips and tricks and you'll be speeding through the airport and having a blast in Siem Reap in no time flat. What to pack in your hand luggage:

  • The trick to having a pain-free flight experience is to be prepared. First up, the essentials: passport, travel docs, bank cards and important medications. Next, bring on board items that'll help pass the time, like your laptop or a magazine. You'll also want to pack your chargers, a comfy neck pillow and a pair of earplugs. And of course, don't forget to squeeze in toiletry items like a toothbrush, facial wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general guide to follow is nothing sharp, flammable or explosive. This includes things like knives, scissors, fuel and fireworks. Sporting equipment like golf clubs, and objects that could harm passengers, such as swords and batons, aren't allowed in the cabin either.

What to wear on a flight:

  • Your goal here is to be as comfortable as possible. Choose a pair of slip-on shoes, dress in loose, natural-fibre clothing and remember to take a pullover in case it gets cold in the cabin.
  • Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-distance flights. Lower your risks by staying hydrated, keeping your lower limbs moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to Siem Reap?
As savvy travellers know, the secret is to be prepared before you reach security. That way, you'll be stepping onto that plane to Siem Reap in next to no time. Follow these tips and get your holiday off to a flying start:

  • Be sure to keep your passport and boarding pass someplace easily accessible. They're the first things you'll be asked to show at airport security.
  • Your belt, coat, keys and other contents of your pockets, like your headphones, will be required to go through the X-ray machine. Make your life easier by removing them before your turn.
  • Your electronic gadgets like phones and laptops will also have to go on a tray to be scanned. Don't worry though, you'll be back online before you know it.
  • Any gels or liquids, such as perfume or hand cream, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several precious minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Knives and other sharp items are not allowed in the cabin. They'll be confiscated at security, so pack them in your checked suitcase.
