How to survive the flight to Koh Samui?
If you're poorly prepared, travelling can be daunting. But don't hit the panic button just yet. Follow these handy hints for a hassle-free start to your time in Koh Samui.What to pack in your hand luggage:

  • Flying can be a great experience if you've got all the right gear. Firstly, you'll want some basic toiletries, such as a toothbrush and lip balm, a clean set of clothes and a good book. Next, leave space in your bag for your electronic gadgets, chargers, your medications and maybe a cosy neck pillow too. Last, but definitely not least, be sure to bring your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hairspray in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) won't be allowed on. Sharp or pointed objects, like your trusty Swiss Army knife, and dangerous goods which are flammable or explosive, such as flares, chemicals agents and gasoline, are also restricted.

What to wear on a flight:

  • The narrow aisles of an airplane are not the place for a fashion parade. Don comfortable layers and remember to bring a cardigan as the temperature can drop inside the cabin. Slightly roomy, flat shoes are also a sensible choice.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clotting condition caused by reduced mobility or inactivity. There are plenty of ways to lessen your risk. Wear a quality pair of compression socks, drink lots of water often and get your legs and feet moving. Do a lap or two of the cabin or try out some simple stretches in your seat.

How to get through airport security fast when flying to Koh Samui?
The secret is to be well organised before you arrive at the security gate. That way, you'll be hopping onto that plane to Koh Samui before you know it. Follow these tips and get your trip off to a flying start:

  • Be sure to keep your passport and boarding pass someplace easily accessible. They're the first items you'll be asked to show at airport security.
  • After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Personal belongings like your belt, jacket and headphones need to go through the machine.
  • For just a few moments, you'll have to unplug from technology. Your phone, laptop and any other electronics will need to go through the scanner.
  • Can't travel without your favourite perfume? Not a problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-lock bag, you can keep it with you in your carry-on luggage.
  • Slip-on shoes are a great footwear choice as you're less likely to have to remove them when passing through security. Big boots and heavier-style shoes are usually subjected to additional screening.
  • Airlines will not allow any sharp items or pocket knives in your carry-on luggage. If you need to bring these kinds of items, check them in.
