Depending on where you're coming from, your journey to Si Thep could be simple and straightforward or it could go on forever. Below are some handy hints that will help you start your next great adventure on a positive note.What to pack in your hand luggage:

  • Traveling on a plane can be a stress-free experience if you take the right stuff. Firstly, you'll want some toiletry items, such as a toothbrush and some deodorant, a spare pair of socks and a good book. Secondly, leave space in your hand luggage for your electronic gadgets, chargers, any vital medications and maybe a blow-up neck pillow as well. Lastly, and most importantly, be sure to take your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by security. Sharp objects, like a pocket knife, and dangerous goods which are flammable or explosive, such as spray paint, flares and gasoline, are also not allowed.

What to wear on a flight:

  • Comfort really should be your prime concern when picking what to wear on your flight. Consider your choice of footwear carefully too, as swollen ankles and feet are a common side effect of flying. Shoes which are flat and slightly roomy are always a smart option.
  • A serious condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It results from blood clots forming due to poor circulation and inactivity. Doing regular leg and foot exercises in your seat helps to prevent this from occurring. Wearing a good-quality pair of compression socks is also recommended.

How to get through airport security fast when flying to Si Thep?
It's easy --- be prepared. We've compiled some handy tips and tricks for a hassle-free trip through security. Watch out Si Thep, here you come:

  • Your travel documents and ID will need to be shown to airport security personnel. Keep them at hand to avoid fumbling around for them.
  • Your jacket, belt, keys and other contents of your pockets, like your earphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • Your electronic devices like phones and laptops will also have to go through the machine to be scanned. Don't worry though, you'll be back online in no time.
  • Any gels or liquids, such as shampoo or hairspray, that you want to bring on board must be no larger than 3.4 ounces (100 milliliters). Also, they all must fit inside a quart-size (one liter), clear zip-close bag.
  • The right choice of footwear can save you several precious minutes. Hiking boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Sharp or pointed items are not allowed in the cabin. They'll be seized at security, so pack them in your checked luggage.
