Do you have any tips for my flight to Koh Samui?
We've pulled together all the info you need to make your flight a pleasant experience. Follow our top tips and you'll be zooming through airport security and enjoying Koh Samui in next to no time. What to pack in your hand luggage:

  • The trick to having a worry-free flight experience is to pack in advance. So, let's start with the essentials: passport, boarding pass, bank cards and daily medications. Next, take on board items that'll help while away those hours, like some electronic gadgets or a good read. You'll also want to pack your chargers, a neck pillow and a pair of headphones. And of course, don't forget to toss in toiletry items like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between airlines, the general rule to follow is nothing flammable, sharp or explosive. This includes screwdrivers, knives, aerosol cans and flares. Sports equipment like hockey sticks, and objects that could harm other people, such as guns and swords, can't come on board with you either.

What to wear on a flight:

  • The aisles of a plane are no place for a fashion parade. Wear layers and choose shoes that are flat, roomy and easy to pull on and off.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To lessen your risk on board, drink lots of water, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Koh Samui?
A little pre-planning before your flight will make your getaway to Koh Samui a breeze. Below you'll find some top tips for a swift journey past security:

  • First things first. Your boarding pass and passport will need to be shown to security personnel. Have them easily accessible so you don't have to dig around for them.
  • 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, coat and headphones will be required to go through the machine.
  • For just a few moments, you'll need to unplug from technology. Your tablet, phone and any other electronic devices must also be sent through the scanner.
  • Travelling with your favourite hand and nail cream? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can keep it with you in your carry-on.
  • Lightweight sneakers are a clever footwear choice as you're less likely to be required to remove them when passing through security. Boots and other heavy-style shoes are often subjected to extra screening.
  • Airlines won't allow any sharp or pointed objects in the cabin. If you must bring these kinds of items, pack them in your checked baggage.
