Made it to South Korea!!!
Arrived in Seoul yesterday and was extremely happy to not see any snow for the first time in quite a while. Thank you so much @infinitejetkorea for all of your help!
This was my longest flight so far with about 6 hour in the air, most of it was also over water. I had to do a huge detour to avoid North Korea as much as possible which ended up working great. I was able to cruise at around 6500 feet for most of the trip.
Tomorrow I am heading further south to a city called Muan, and then Taiwan the day after :)
