How to survive the flight to Dong Sing?
Depending on where you’re coming from, your trip to Dong Sing could be as easy as pie or it could go on forever. We’ve put together some handy travel tips that will help you start your next unforgettable escape on a positive note.What to pack in your hand luggage:

  • Air travel can be a comfortable experience if you carry the right things. Firstly, you’ll need basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a spare set of clothes and something to read. Next, find a spot in your carry-on bag for your phone and charger, any daily medications and maybe a neck pillow too. Lastly, and most importantly, remember to take your passport, travel docs 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 liquids or gels in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by security. Pointed or sharp objects, like your beloved Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosol cans, spray paint and fireworks, are also banned.

What to wear on a flight:

  • The aisles of your plane are not the place for a fashion parade. Wear comfortable clothes and don’t forget to bring a cardigan as the temperature can drop in the cabin. Enclosed, flat shoes are also recommended.
  • The condition called deep vein thrombosis (DVT) can pose a risk on long-distance flights. It’s the result of blood clots forming due to inactivity and poor circulation. Walking up and down the aisle and doing leg and foot exercises in your seat helps to prevent this from occurring. Wearing a pair of compression socks or tights also helps reduce your risk.

How to get through airport security fast when flying to Dong Sing?
The secret is to be well prepared before you arrive at airport security. That way, you’ll be boarding that plane to Dong Sing before you know it. Follow these tips and get your trip off to a great start:

  • First things first. Your boarding pass and passport will need to be shown to security personnel. Keep them handy so you don’t have to dig around for them.
  • Time to strip down. Well kind of. Your coat, belt, keys and other small items, like your earphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • For just a few moments, you’ll have to unplug from technology. Your tablet, phone and any other electronic gadgets will also need to be sent through the scanner.
  • Want to bring along your favourite hand and nail cream? No problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it’s stored in a zip-lock bag, it’s fine to bring with you on board.
  • It’s also likely that you’ll need to remove your shoes to be X-rayed, so wearing slip-on shoes is always a clever idea.
  • Sharp or pointed items can’t be taken on board. They’ll be confiscated at security, so pack them in your checked suitcase.
