  • Departing from or arriving at other airports can sometimes help you cut costs. Enter your preferred departure and arrival airports. Next, click on the ‘Nearby airports’ function below to see your options.

  • Book your airfare as soon as you’ve figured out your travel dates. While you can get lucky once in a while, tickets rarely get more affordable as your date of departure gets closer.
  • Make serious savings on your getaway by combining your hotel, flights and car rental into an Orbitz package. Your travel budget will thank you.

What do I need for the flight to Koh Samui?
The trick to having a smooth and stress-free flight is to arrive prepared. Here are a few tips to keep in mind before you depart:

  • Nothing is more important than having your travel documents. Which to bring and how many depend on whether you’re flying domestic or international. Be sure to double check with your airline. In both cases, you’ll need to show some type of government-issued ID.
  • Bring a good book or a laptop crammed with your favorite films — it’ll help to while away time during your journey to Koh Samui. Or if you’re hoping to enjoy a snooze, an eye mask will shield you from those bright cabin lights.
  • Cabin temperatures can make your teeth chatter. Pack a sweater even if you’re heading off during the peak of summer.

  • Many budget carriers these days offer comfortable business-class seating that doesn’t cost the earth.
  • Make a bid for an upgrade. Some airlines hold online auctions that let you put down a price for a seat at the front of the plane. You may also be able to upgrade with points earned through a rewards program.
