Great fare to my second home. If you missed the launch fares then consider this a second chance. $372 return in December is a steal. A direct flight with Korean Air during the same period would usually be around $1500.
One way fares starting from $199. Great price if you're thinking of going to the DMZ and then taking a casual stroll across the border and into the NK hard labour camps.
