Ok so how much time will it take to travel from Korea to Vancouver and what's the normal airplane speed? And is it possible to reach Vancouver in 5 hours because the online flight I have seen says 5 hours but I checked in some site and it said 10 hours.How much time will it take to travel from korea to vancouver?I was flew there in April from San Francisco and it took me 11 hours to get there and 10 hours to get back. Vancouver and San Francisco is relatively in the same area. I say it's somewhere between 9-11 hours.
