Sadly my Korean isn’t that great (heck, I got by in Korea with 10 words I think), but this web page from Asiana gives a hint:

There are two dates in this: 18th April 2012 and 31st May 2012.
I’d guess the 31st May may referrer to the Star Alliance Company Plus.
Like it or not – the end is coming soon…
Asiana says that BMI will leave Star Alliance on Apr.18.
And, members of Asiana can use their mileage for booking BMI until May 31. 🙂
Thanks! I really have to brush up on my Hangul one day 😉
