Just SLF but also have lived 12 years as an expat in Korea. There may be lots of 'issues' here regarding management of Korean companies, to the point that I will not fly a Korean airline - BUT the insurance thing notes above is not an issue as it is common for Koreans to buy insurance (which are really just a kind of savings plans that have a tiny insurance portion so that they can legally be sold by insurance companies). Basically, the captain buying insurance is a lead to be checked, but most likely nothing unusual.
