How to survive the flight to Tha Sai?
If you're not prepared, air travel can be testing. But there's no need to hit the panic button just yet. Follow these useful tips for a comfortable start to your holiday in Tha Sai.What to pack in your hand luggage:

  • The trick to having an awesome flight experience is to be prepared. So, let's start with the basics: passport, official ID, cash and daily medications. Next, bring items that'll help keep you busy, like some electronic gadgets or a good read. It's also smart to bring your chargers, a comfy neck pillow and a pair of earphones. Last but not least, don't forget to squeeze in toiletry items like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a Swiss Army knife hiding in one of the compartments of your carry-on luggage. Other banned items include explosive or flammable substances, like aerosols and matches, and gels and liquids in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Comfort should always be the goal when deciding what to wear on board. Consider your footwear carefully too, as swollen ankles and feet are a common side effect of flying. Slightly roomy, flat shoes are always a good idea.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by reduced mobility or inactivity. There's plenty you can do to mitigate your risk. Wear a pair of compression socks, stay well hydrated and remember to keep your legs and feet moving. Wander around the cabin or perform some stretches in your seat.

How to get through airport security fast when flying to Tha Sai?
Being organised before you arrive at the airport can make your trip to Tha Sai a breeze. Below are some handy hints for a speedy journey through security:

  • Airport security personnel first need to see that you have a valid ID and travel documents before you can proceed any further. Keep them close by.
  • 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 such as your coat, belt and headphones will be required to go through the machine.
  • Your electronic devices like laptops and phones will also need to go on a tray to be scanned. No need to worry though, you'll be back online in no time.
  • Remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to be asked to remove them when passing through security. Safety boots and other bulky shoes are usually subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked suitcase. They won't be allowed in the cabin.
