Do you have any tips for my flight to Siheung?
No matter where you're coming from, flying can be a pleasant experience if you've planned ahead. Take a peek at these top travel tips that will help get your Siheung vacation started on the right note. What to pack in your hand luggage:

  • Air travel can be a cruisy experience if you carry the right things. Firstly, you'll need basic toiletries, such as a toothbrush and lip balm, a clean set of clothes and a magazine or two. Secondly, find a spot in your bag for your mobile phone, a charger, your medications and maybe a quality neck pillow as well. Lastly, and most importantly, be sure to take your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes knives, scissors, spray paint and flares. Sporting equipment like ski poles, and objects that could harm other people, such as firearms and swords, aren't allowed in the cabin either.

What to wear on a flight:

  • Choose comfort over style. Prepare for changes in temperature by wearing layers, and opt for slightly roomy, flat shoes like sneakers.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long flights. Reduce the risks by staying hydrated, keeping your ankles and legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Siheung?
The answer is simple — be organized. We've compiled some top tips for a fuss-free trip through airport security. Look out Siheung, here you come:

  • Airport security personnel first need to make sure that you have a valid ID and matching travel documents before you can proceed any further. Have them within easy reach, ready for inspection.
  • Time to strip down. Well sort of. Your jacket, belt, keys and other small items, like your earphones, will be required to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • 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.
  • Traveling with a new cologne or perfume? No problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a clear zip-lock bag, it's fine to bring with you in your carry-on bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when passing through security. Boots and other bulky shoes are usually subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won't be allowed on board and will be confiscated.
