How to survive the flight to Khon San?
If you're not prepared, air travel can be tough. But there's no need to worry. Follow these helpful hints and enjoy a worry-free start to your time in Khon San.What to pack in your hand luggage:

  • It's easy --- first, put in your passport, travel documents, bank cards and medications. Next, you'll want some extra in-flight entertainment to while away the time. A juicy book and a phone filled with your favorite movies are some wonderful options. If you plan to take a quick snooze, a quality neck pillow and a pair of noise-canceling headphones will also be useful. Finally, squeeze in a toothbrush and some cleansing wipes so you'll hop off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a pocket knife) hiding in the bottom of your hand luggage. Other restricted items include flammable or explosive products, such as fuel and fireworks, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The key to a comfortable flight can be as simple as your choice of clothing. Prepare for changes in temperature by bringing layers. This will keep you nice and warm if the cabin gets too cold. Shoes like flip flops and heels are best left in your checked suitcase. Instead, opt for flat, closed-toed footwear like sneakers. Your feet will thank you later.
  • Caused by sustained periods of immobility, DVT (deep vein thrombosis) is a blood clot condition that can affect some passengers during long-haul flights. But the good news is there are ways to reduce your risk of developing it. Drink plenty of water, walk up and down the aisles as much as possible and wear compression tights or socks.

How to get through airport security fast when flying to Khon San?
The secret is to be prepared before you get to security. That way, you'll be hopping onto that plane to Khon San in no time at all. Follow these tips and get your trip off to a terrific start:

  • Be sure to have your passport and boarding pass someplace easily accessible. They're the first items you'll be asked to present to security.
  • Time to strip down. Well kind of. Your belt, coat, keys and other contents of your pockets, like your earphones, will need to go 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 on a tray to be scanned. Don't worry though, you'll be back online in no time.
  • Remember to remove liquids and gels from your carry-on luggage. They often need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one liter), clear zip-lock bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to be required to remove them when going through security. Safety boots and heavier-style shoes are often subjected to extra screening.
  • Airlines won't allow any sharp objects in your hand luggage. If you must bring these kinds of items, put them in your checked luggage.
