Do you have any tips for my flight to Koh Ouen?
Depending on where you're coming from, your journey to Koh Ouen could be completely stress-free or it could go on forever. We've rounded up some useful tips that will help you start your next great escape on the right foot. What to pack in your hand luggage:

  • Traveling on a plane can be a great experience if you bring the right gear. Firstly, you'll need toiletry items, such as toothpaste, a toothbrush and some deodorant, a fresh change of clothes and a good novel. Secondly, find room in your carry-on bag for your laptop, a charger, any daily medications and maybe a proper neck pillow as well. Lastly, be sure to bring your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a Swiss Army knife lurking in your carry-on luggage. Other restricted items include explosive or flammable substances, such as bleach and fuel, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your goal here is to be as comfortable as possible. Go for a pair of flat, closed-toe shoes, dress in loose, breathable clothing and don't forget to take a pullover in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some gentle exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Koh Ouen?
The simple answer is — be prepared. We've compiled some top tips for a stress-free trip through security. Watch out Koh Ouen, here you come:

  • First things first. Your passport and boarding pass will need to be presented to airport security personnel. Keep them within easy reach so you don't hold up the queue.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, take off anything that might set the alarms off. Items like your belt, coat and headphones need to go through the machine.
  • All your electronic gadgets, including your laptop and phone, will also need to be scanned separately.
  • Any liquids or gels, such as shampoo or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, they all must fit inside a quart-size (one liter), zip-lock bag.
  • There's a good chance you'll be required to take your shoes off for scanning, so wearing slip-on shoes is always a good idea.
  • Airlines won't allow any sharp or pointed objects in your carry-on luggage. If you must bring these kinds of items, check them in.
