Check online and see when your qualification period ends. From the "My Mileage Summary", click on the "Upgrading/Maintaining" section. Then it will list it under, "Activity Qualification Period" For me, I double checked with the Asiana Club desk and what shows up on the website is the real end of the qualification period. For me, the "Date of Enrollment in Program" is totally bogus. I enrolled long before the date shown and earned my initial D+ status before that date. So it might be right for you, but if it's wrong you can ignore it.

So if you don't have a qualification period ending a month beyond when you expected, I don't think you'll have that extra time. My guess is that they initially had a month's grace period for status, and somehow programmed their system to also give a month's grace period for qualification, but it likely messed up some people's plans for qualifying if they were crediting miles at the beginning of a new period for their next status period. Anyways, they claim the system has been corrected, and if the date of correcting it was prior to you registering with Asiana Club, there will be no extra month. If the correction was made after you joined, then I'm guessing the period shown online will reflect that additional month.
