Good news for those wondering about extensions, my evaluation period was supposed to lapse on March 31 but it appears to have been extended by another year. It was already extended last year; my evaluation base date for my current period is Apr. 1, 2019, and that would have ordinarily lapsed March 31, 2021, but now is good through March 31, 2023. I get to keep my Diamond status (fwiw I was 3650 mi short of requalifying. I don't know if it was extended because I was so close to the requirement, or if they're extending everyone. I didn't receive any communication from Asiana).
