I got an upgrade to premium economy on Cathay Pacific

My seat upgrade was successfully done. As I mentioned in my previous blog, I was asking for a seat upgrade to premium economy using my Asia miles two days before. I need 10,000 miles to upgrade for one-way between Seoul and Hong Kong. Today, I received a confirmation e-mail from Cathay Pacific. They gave me a 34A seat, it's the rear left side section of premium economy.
