The flight to Korea is over 10 hours all together so I decided to put together a list of things to make it more comfortable. First, make sure everything is fully charged. My iphone holds all my books and music so the last thing I need is that to run out of power. Also make sure wireless headphones are fully charged as well. I also bring a travel pillow so I can sleep comfortably. Important tip: the less you bring the more comfortable you will be. For example, my carryon is a small backpack so I still have lots of legroom. Lastly, I bring my glasses so I can sleep.
