I've heard rumors that sometimes when a MPC member changes to a higher tier, he/she will suddenly get an upgrade on the next flight. Is that true? I know that when I joined MPC, the first flight I took was an upgrade to J. From HKG-YYZ.
Happened to me Y-J when I went from GR to SL HKG-SIN last year, and there was no op reason for it...Y was half empty. But when I went from SL-GO and GO-DM I didn't get squat.
