Thanks for all the replies!
I'm just curious if access were still possible if I purchase an economy or PEY ticket, then used miles to upgrade? (supposing that is possible with Asiamiles)
I have not flown any OW carrier in the past four years, since I moved over to SkyTeam. Before I had status with CX about six years ago, that airline did not allow any access to the Business Lounge if on a purchased Y/PEY ticket, that was upgraded to business.
I have not had any Asiamiles activity so my miles are expiring this April.
