Read the fine print.  You don't want to get screwed.   
On some coach fares, you can transfer the unused portion to another ticket usually within a year. But again read the fine print.(Of course there would be change fees).
I am not sure about your question about a Korean entering Canada from Seattle. Do you expect difficulties from American or Canadian customs?
