How to survive the flight to Sejong?
Wherever you're jetting in from, flying can be a seamless experience if you've planned ahead. Follow these essential travel tips that will get your Sejong vacation started on the right note.What to pack in your hand luggage:

  • Air travel can be a great experience if you pack the right gear. Firstly, you'll want some basic toiletry items, such as a toothbrush and lip balm, a fresh change of clothes and a good novel. Next, leave space in your hand luggage for your laptop, a charger, medications and perhaps a neck pillow as well. Lastly, and most importantly, remember to bring your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of hair gel and hairspray in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by security. Sharp objects, like your trusty pocket knife, and dangerous products which are explosive or flammable, such as flares, bleaching agents and gasoline, are also restricted.

What to wear on a flight:

  • The best way to ensure a comfortable flight is as simple as your choice in clothes. Prepare yourself for varying temperatures by layering up. That way you'll stay nice and warm if the cabin starts to cool down. Shoes like high heels and sandals are best left in your suitcase. Even though they may be your favorites, opt for flat, closed-toed footwear like sneakers. Your feet will thank you for it.
  • A condition called deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clotting due to poor circulation. Doing leg and foot exercises in your seat helps to prevent this happening. Wearing a pair of compression tights or socks can also help.

How to get through airport security fast when flying to Sejong?
Being organized before you arrive at the airport will help make your getaway to Sejong easy and painless. Below you'll find some handy tips for a speedy journey past security:

  • Airport security personnel first need to determine that you have a valid ID and boarding pass before you're allowed to proceed any further. Have them ready to show.
  • Your belt, coat, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • Your electronic devices like laptops and phones will also need to go on a tray for inspection. No need to worry though, you'll be back online in no time.
  • Don't forget to remove gels and liquids from your hand luggage. They often need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-close bag.
  • There's a good chance you'll need to take your shoes off for scanning, so wearing slip-on shoes is always a good idea.
  • Airlines will not allow any sharp objects in the cabin. If you need to bring these kinds of items, pack them safely in your checked luggage.
