Do you have any tips for my flight to Siem Reap?

  • Get your vacation off to a wonderful start by being prepared. Pack your passport, travel documents and any medications you need first. After that, consider downloading some movies on your tablet or phone for a binge session sans guilt. Or, throw in that juicy novel you haven’t had time to read. Lastly, a few tasty snacks and a good neck pillow will go a long way to making the journey as comfy as possible.
  • There’s a lengthy list of items you shouldn’t pack in your carry-on too. Explosives, flammables and sharps are strictly prohibited in the cabin — they often include aerosol cans, flares, box cutters and razor blades. Some sporting equipment, like tennis rackets and baseball bats, are also not allowed in your hand luggage. Visit your airline’s website for details about what you can and can’t take on board.

What to wear on a flight:

  • The aisles of a plane aren’t designed for a fashion show. Layer up in comfy clothing and bring a sweater since it can get cool in the cabin on long-haul flights. Closed-toe shoes are perfect for longer journeys.
  • The condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting due to poor circulation and inactivity. Walking up and down the aisle and doing leg and foot exercises while seated can help prevent this developing. Wearing compression tights or socks also helps to lessen your risk.

How can I get a cheap last-minute flight to Siem Reap?
The key to booking a cheap, spur-of-the-moment flight to Siem Reap is to be flexible. You can boost your chances of scoring a fabulous deal if you’re not tied to specific travel dates, flight times and airlines. Also compare the prices of flying out of and into alternative airports if that’s an option.
Where can I learn more about changing or canceling my flight to Siem Reap?
Most flights are free to cancel within 24 hours of making the reservation. However, some flights are non-refundable, and you may receive a flight credit from the airline to use for a future booking. For more information, please visit our Customer Service Portal.
