Do you have any tips for my flight to Seongnam?
Depending on where you're coming from, your flight to Seongnam could be simple and straightforward or it could go on forever. We've compiled some useful travel tips that will help you start your next great adventure on the right foot. What to pack in your hand luggage:

  • The trick to having a great travel experience is to plan ahead. Start with the essentials: passport, official ID, bank cards and medications. Next, take on board items that'll help pass the time, like some electronic gadgets or a thrilling book. You'll also want to bring your chargers, a quality neck pillow and a pair of earphones. And of course, be sure to pop in toiletry items like a toothbrush, cleansing wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your treasured pocket knife, and dangerous goods which are flammable or explosive, such as flares, bleaching agents and poisons, are also restricted.

What to wear on a flight:

  • Go for comfort over style. Prepare for temperature changes by dressing in layers, and opt for flat, closed-toe shoes like slip-ons.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-distance flights. Reduce the risks by staying hydrated, keeping your feet and legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Seongnam?
It's easy — be prepared. We've compiled some tips and tricks for a fuss-free trip through airport security. Watch out Seongnam, here you come:

  • Have your passport and travel documents within easy reach. They're the first things you'll be asked to show at airport security.
  • Next up, both you and your carry-on luggage must be X-rayed. To speed things up, take off anything that is likely to set the alarm off. Items such as your belt, jacket and headphones need to go through the machine.
  • Your electronic gadgets like phones and laptops will also have to go through the machine for inspection. No need to worry though, you'll be back online before you know it.
  • Any gels or liquids, such as perfume or hairspray, 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), zip-lock bag.
  • It's also possible you'll need to take your shoes off to be X-rayed, so wearing slip-on shoes is always a wise idea.
  • Sharp items are not allowed in the cabin. They'll be confiscated at security, so pack them in your checked luggage.
