How to survive the flight to Osan?
If you’re not prepared, air travel can be tough. But don’t hit the panic button just yet. Follow these helpful hints for a pain-free start to your holiday in Osan.What to pack in your hand luggage:

  • A plane trip can be a great experience if you carry the right gear. First things first, you’ll need basic toiletries, such as deodorant and a toothbrush, a spare change of clothes and a good novel. Next, make room in your bag for your laptop, a charger, any medications and maybe a blow-up neck pillow too. Lastly, and most importantly, remember to take your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

  • Check carefully that you don’t have sharp objects (like a knife or scissors) lurking in your carry-on luggage. Other prohibited items include explosive or flammable goods, like aerosols and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Comfort really should be your highest priority when selecting what to wear on board. Consider your footwear choice with care too, as swollen feet and ankles can be a side effect of flying. Flat, slightly roomy shoes are always a sensible way to go.
  • Unfortunately, a risk of long-distance travel is developing deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity. To avoid this, take every opportunity to walk around the cabin and stretch your legs. Compression tights and socks are another easy way to help minimize this risk.

How to get through airport security fast when flying to Osan?
Being organised before your flight will make your trip to Osan a piece of cake. Read through our handy tips for a speedy journey through security:

  • Keep your boarding pass and ID within close reach. They’ll be the first things you’ll be asked for by airport security.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to set off the alarm. This includes things like earphones or headphones, as well as heavy jackets or coats. They’ll need to be placed on the conveyor belt for screening.
  • All electronic devices, including your phone and tablet, are also required to be scanned separately.
  • Any liquids or gels, such as shampoo or hairspray, that you want to take on board need to be in containers no larger than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • The right choice of footwear can save you valuable minutes. Hiking boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won’t be allowed on board.
