Do you have any tips for my flight to Sejong?
Depending on where you're coming from, your journey to Sejong could be as easy as pie or it could go on forever. We've put together some tips that will help you start your next big adventure on a positive note. What to pack in your hand luggage:
  • Firstly, and most importantly, pack in your passport, travel documents, credit cards and daily medications. Next, you'll want some entertainment to help pass the time. A thrilling novel and a tablet crammed with your favourite movies are some fantastic options. If you hope to catch more than just forty winks, a comfy neck pillow and some earplugs will also be useful. Finally, leave space for a few toiletry items to ensure you arrive looking fresh and ready to go.
Do not pack the following items in your hand luggage:
  • Leave all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your beloved Swiss Army knife, and dangerous products which are explosive or flammable, such as spray paint, flares and strong acids, are also not allowed.
What to wear on a flight:
  • Comfort should be your top priority when choosing what to wear on board. Loose, breathable clothing is a sensible choice, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-haul flights. It results from blood clots forming due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.
How to get through airport security fast when flying to Sejong?
Being prepared before you arrive at the airport will make your getaway to Sejong easy and painless. We've compiled some handy tips and tricks for a stress-free journey past security:
  • Be sure to keep your travel documents and ID close by. They'll be the first things you'll be asked to present to airport security.
  • After that, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that might trigger the alarms. Items like your belt, coat and earphones need to go through the machine.
  • All electronic gadgets, including your laptop and phone, must also be scanned separately.
  • Any gels or liquids, such as shampoo or hand cream, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several valuable minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
  • Sharp or pointed items can't be taken on board. They'll be seized at security, so pack them safely away in your checked suitcase.
