Firstly, you'll want a few toiletry items, such as deodorant and a toothbrush, a fresh set of clothes and a good book. Secondly, leave space in your bag for your laptop, a charger, any vital medications and maybe a quality neck pillow too. Lastly, and most importantly, be sure to take your passport, travel docs and some cash. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items can differ between air carriers, the general rule of thumb is nothing sharp, flammable or explosive. This includes screwdrivers, knives, spray paint and fireworks. Sporting equipment like hockey sticks, and objects that could harm other people, such as pepper spray and firearms, aren't allowed in the cabin either. > > > What to wear on a flight: > > > - Your main priority is to feel as comfortable as possible. Go for a pair of flat, closed-toe shoes, dress in loose, natural-fibre clothing and don't forget to bring a sweater in case it gets chilly in the cabin. > - The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-distance flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression tights or socks. ### How to get through airport security fast when flying to Onsan-eup? > - Security personnel first need to check that you have a valid passport and matching travel documents before anything else. Have them within easy reach, ready for inspection. > - Time to strip down. Well kind of. Your jacket, belt, keys and other small items, like coins, will be required to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives. > - All your electronics, including your laptop and phone, will also need to be scanned separately. > - Can't travel without your favourite cologne or perfume? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can keep it with you in your carry-on bag. > - The right choice of footwear can save you a few precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on shoes usually aren't. > - Airlines won't allow any sharp objects in your carry-on baggage. If you must bring these kinds of items, pack them safely in your checked luggage. ## Book with confidence # Expedia flights to Onsan-eup Searching for cheap flights to Onsan-eup?
