Never travel without one
I bought the insurance at the 3rd floor of Incheon Airport. There are about four insurance companies offering different coverages. It only took me 15 minutes to purchase ours. The insurance clerks didn’t speak English and the forms were all in Korean but I was given an English booklet explaining the coverage. For some, it would be easier to get an insurance quote online. They can also choose the type of insurance that will suit them best. It’s really good to compare insurance to get the best value.
I got the insurance for 57,000 won for my son and I. We never use them and I’m glad we didn’t! It’s not money down the drain because it gave me the peace of mind that we’re protected.
