Three out of every 10 people traveled alone last year when they went overseas, an analysis shows.
Interpark Tour said on Wednesday that it analyzed 4.62 million international flight tickets it sold last year and found that 32 percent were bought for one person.
Among them, 38 percent were booked by those in their 30s, followed by 20-somethings at 33 percent. Women bought 52 percent of the one-person tickets, suggesting they traveled alone more than men.
The top destination was Tokyo, followed by Shanghai, Osaka, Bangkok and Hong Kong -- all Asian cities relatively close to Korea.
An Interpark spokesman said, "Those who travel alone seem to prefer easily accessible places, rather than going far away."
Meanwhile, the popularity of Iceland soared last year after a cable TV show featured a trip to the North European country. Booking rates for flights to the country increased 45 times on-year last year.
