Firstly, you'll need basic toiletry items, such as deodorant and a toothbrush, a fresh set of clothes and a good read. Next, leave space in your carry-on bag for your mobile phone, a charger, medications and maybe a cozy neck pillow too. Last, but definitely not least, remember to bring your passport, travel papers and your credit cards. > > > Do not pack the following items in your hand luggage: > > > - Make sure you don't have a pocket knife hiding in one of the zippers of your carry-on luggage. Other banned items include explosive or flammable products, such as aerosol cans and bleach, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Your main aim is to feel as comfortable as you can. Opt for slip-on footwear, dress in loose, natural-fibre clothing and don't forget to take a pullover in case you get cold in the cabin. > - Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some simple exercises in your seat to improve your circulation. ### How to get through airport security fast when flying to Osan? > - Your boarding pass and travel ID will need to be inspected by airport security. Have them close by so you don't hold up the line. > - Time to strip down. Well sort of. Your jacket, belt, keys and other contents of your pockets, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them as your turn draws near. > - All electronic gadgets, including your phone and laptop, must also be scanned separately. > - Any liquids or gels, such as lip balm or cologne, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag. > - It's also possible you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a smart idea. > - Sharp items like knives are not allowed in the cabin. They'll be confiscated at security, so pack them safely away in your checked luggage. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Osan.
