I don't know if this was advertised or notified anywhere, but Asiana has issued discount coupons for any flight purchase between Jan-Apr 2023. I'm assuming it's for those who hold status as my wife received a 5% off voucher as a Diamond, and I received a 10% off voucher as Plat.

It's a bit restrictive as flights have to commence by May 2023, but still will be useful for some people.
