I'm back in Korea next week. As usual I fly Korean Air, which is part of the Hanjin Group.
That said, Arirang News notes...
When it comes to air travel, Korean airliners may be the safest way to fly.
The UN's International Civil Aviation Organization says Korea ranked first for aviation safety so far with a 98.89 percent performance rating by international standards. The organization's rating was introduced in 1995 in the wake of a rising number of accidents in the early 90s.
BTW Korea Air has ordered six Airbus A330 aircraft for use on routes linking Seoul with Europe and North America. I expect, I'll be traveling in one of the new A330s when they are in operation.
