How to survive the flight to Lang Son?
Wherever you're jetting in from, flying can be a seamless experience if you're well prepared. We've compiled a list of handy travel tips that will help get your Lang Son vacation started on the right note.What to pack in your hand luggage:

  • The secret to having a stress-free flight experience is to pack in advance. So, let's start with the basics: passport, travel docs, bank cards and daily medications. Next, take on board items that'll help while away those hours, like some electronic devices or a good read. It's also a wise idea to bring your chargers, a 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:

  • Pack all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Pointed or sharp objects, like your trusty pocket knife, and dangerous goods which are explosive or flammable, such as spray paint, flares and fireworks, are also restricted.

What to wear on a flight:

  • The long, narrow aisles of your airplane are no fashion runway. Layer up with comfortable clothing and remember to bring a cardigan as it tends to get cool in the cabin on long-haul flights. Flat, enclosed shoes are also recommended.
  • The result of sustained periods of inactivity, DVT (deep vein thrombosis) is a blood clotting condition that can affect some passengers during long flights. But the great news is there are ways to lower your risk of developing it. Keep your fluids up, wander around the cabin as much as you can and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to Lang Son?
Being prepared before you get to the airport will make your getaway to Lang Son quick and painless. Here are some handy hints for a speedy journey past security:

  • Keep your travel documents and ID someplace easily accessible. They're the first things you'll be asked for by airport security.
  • Next up, both you and your carry-on luggage must be X-rayed. To speed things up, remove anything that might set the alarms off. Personal belongings like your belt, coat and earphones need to go through the machine.
  • All your electronic gadgets, including your phone and tablet, are also required to be separately scanned.
  • Remember to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner 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.
  • There's a chance you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked baggage. They won't be allowed on board.
