Perhaps a mistake?
I did not get the requalification email and it seems relatively few got the email. I wonder if the email was mistakenly sent out in advance?
I am currently over 70K full fare miles (70% C/D/Z and remaining B) and 140K EQM. Have travel booked to finish year with well over both 80K FF and 150K EQM. I earlier received the "we are watching you" mail regarding GS requalification. While nothing is certain, I would be surprised if I did not requalify.
Maybe the qualification email was not supposed to be sent out until later in the year and it went out only to a subset of people who have qualified?
