Do you have any tips for my flight to Ongsaengi-gol?
No matter where you're coming from, flying can be a seamless experience if you prepare well enough. We've put together a list of handy tips that will get your Ongsaengi-gol escape started on the right note. What to pack in your hand luggage:

  • Flying can be a comfortable experience if you carry the right things. First of all you'll need toiletry items, such as a toothbrush and some deodorant, a spare change of clothes and a good read. Next, make room in your bag for your mobile phone, a charger, any daily medications and maybe a neck pillow as well. Lastly, don't forget to bring your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects hiding in your carry-on luggage. Other prohibited items include explosive or flammable goods, such as aerosol cans and bleach, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The aisles of an airplane aren't the place for a fashion parade. Layer up with comfy clothing and opt for shoes that are flat, enclosed and easy to remove.
  • Most travelers are aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To lessen your risk on board, drink lots of water, consider wearing compression socks or tights and move your legs and feet often.

How to get through airport security fast when flying to Ongsaengi-gol?
As savvy travelers know, the secret is to be prepared before you arrive at airport security. That way, you'll be hopping onto that plane to Ongsaengi-gol in next to no time. Follow these tips and get your trip off to a terrific start:

  • Security personnel first need to determine that you have a valid ID and matching boarding pass before anything else. Keep them close by.
  • Time to strip down. Well sort of. Your belt, coat, keys and other contents of your pockets, like coins, will be required to go through the X-ray machine. Make your life easier by removing them before your turn arrives.
  • Your electronic gadgets like phones and laptops will also need to go on a tray for inspection. Don't worry though, you'll be back online soon enough.
  • Can't travel without your favorite cologne? No problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-close bag, you're allowed to bring it with you on board.
  • The right choice of footwear can save you several precious minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Airlines won't allow any sharp objects in the cabin. If you must bring these kinds of items, put them in your checked luggage.
