How to survive the flight to Si Thoi?
If you’re not prepared, air travel can be a real challenge. But there’s no need to panic. Follow these tips and tricks for a stress-free start to your time in Si Thoi.What to pack in your hand luggage:

  • The secret to having a stress-free travel experience is to pack ahead. Start with the essentials: passport, official ID, cash and important medications. Next, take on board items that’ll help keep you entertained, like some electronic devices or a thrilling book. It’s also smart to bring your chargers, a comfy neck pillow and a pair of earphones. Finally, be sure to squeeze in toiletry items like a toothbrush, facial wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes things like knives, scissors, fireworks and fuel. Sporting equipment like golf clubs, and objects that could injure passengers, such as pepper spray and firearms, won’t be allowed on board either.

What to wear on a flight:

  • Your goal here is to make yourself as comfortable as possible. Layer yourself up in natural-fibre clothing and remember to bring a cardigan in case it gets cool. Pick a pair of well-fitting, flat shoes as it’s possible that your feet and ankles will swell a little during the journey. Leave the high heels and hiking boots in your main luggage.
  • You’ve probably heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. There are numerous ways to mitigate your risk. Wear compression tights or socks, stay hydrated and keep your legs and feet moving. Do a few laps of the cabin or perform some stretches in your seat.

How to get through airport security fast when flying to Si Thoi?
The secret is to be well prepared before you reach airport security. That way, you’ll be boarding that plane to Si Thoi before you know it. Follow these helpful tips and get your trip off to a spectacular start:

  • Airport security personnel first need to know that you have a valid passport and boarding pass before you can proceed any further. Have them within easy reach, ready for inspection.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to beep. This includes things like headphones or earphones, as well as heavy coats or jackets. They’ll all need to go on the X-ray conveyor belt.
  • Your electronic devices like laptops and phones will also have to go on a tray to be scanned. No need to worry though, you’ll be back online in no time.
  • Can’t travel without your favourite hand cream? No problem. As long as it’s in a container no larger than 3.4 ounces (100 milliliters) and it’s stored in a zip-lock bag, it’s fine to bring with you in your carry-on luggage.
  • It’s also likely that you’ll be required to remove your shoes for scanning, so wearing slip-on sneakers is always a smart idea.
  • Airlines will not allow any sharp or pointed objects in your carry-on baggage. If you need to bring these kinds of items, put them in your checked luggage.
