So, let's start with the essentials: passport, boarding pass, cash and medications. Next, bring items that'll help keep you occupied, like your laptop or a magazine. You'll also want to pack your chargers, a comfy neck pillow and a pair of headphones. Last but not least, 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: > > > - While the list of banned items can differ between air carriers, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes things like knives, scissors, fuel and fireworks. Sports equipment like golf clubs, and items that could injure passengers, such as swords and batons, are also banned from the cabin. > > > What to wear on a flight: > > > - You'll want to go for comfort over style. Prepare for temperature changes by dressing in layers, and pick slightly roomy, flat footwear like sneakers. > - Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some gentle exercises in your seat to improve your circulation. ### How to get through airport security fast when flying to Seosan? > - Airport security personnel first need to check that you have a valid passport and boarding pass before anything else. Have them ready to show. > - Time to strip down. Well kind of. Your coat, belt, keys and other small items, like your earphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as your turn draws near. > - All your electronic gadgets, including your phone and laptop, must also be separately scanned. > - Travelling with a new hand and nail cream? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, it's fine to bring with you in your carry-on. > - The right choice of footwear can save you several valuable minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Lightweight sneakers are usually not. > - Pocket knives and other sharp items can't be taken on board. They'll be seized at security, so pack them safely away in your checked baggage. __Flights to Seosan information__ | Destination airport | Incheon Intl. | | ----------------------------- | ------------- | | Destination airport IATA code | ICN | | Destination city name | Seoul | | Return price | £118 | ## Trending flights to Seosan Prices were available within the past 7 days and start at £59 for one-way flights and £119 for round trip, for the period specified.
