Do you have any tips for my flight to Seoul?
We've got the lowdown on how to make your journey as pain-free as possible. Follow our tips and you'll be speeding through airport security and seeing the best of Seoul in no time at all. What to pack in your hand luggage:

  • The trick to having a hassle-free travel experience is to pack in advance. First up, the essentials: passport, travel docs, bank cards and any vital medications. Next, bring on board items that'll help while away those hours, like some electronic devices or a thrilling book. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to squeeze in toiletry items like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects lurking in one of the zippers of your carry-on luggage. Other prohibited items include explosive or flammable goods, such as fuel and fireworks, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of an aircraft aren't the place for a fashion parade. Dress in comfortable layers and opt for shoes that are flat and easy to slip on and off.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To minimize your risk on board, drink lots of water, consider wearing compression socks and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Seoul?
The secret is to be well organised before you reach the security gate. That way, you'll be stepping onto that plane to Seoul in a flash. Follow these helpful tips and get your holiday off to a spectacular start:

  • Security personnel first need to make sure that you have a valid ID and boarding pass before you can proceed any further. Have them within easy reach, ready for inspection.
  • After that, both you and your carry-on bag will be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items like your jacket, belt and headphones will be required to go through the machine.
  • For just a few moments, you'll need to unplug from the digital world. Your phone, tablet and any other electronics must also go through the scanner.
  • Any gels or liquids, such as hair oil or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
  • It's also likely that you'll need to take your shoes off for scanning, so wearing slip-on sneakers is always a smart idea.
  • Pocket knives and other sharp items can't be taken on board. They'll be seized at security, so pack them in your checked baggage.
