Last time I got row 1 (as silver) was in November last year. It was also the last time I tried to get seats in row 1 at T-72. On all my flights in between then and now expert flyer showed them as occupied.
I did also try calling (as that has also worked for me in the past when inside 72 hours) and the message I got from the call centre this time was those seats are "restricted" and I don't think they even tried to move me.
Anyway, that flight is done and onwards to the next. (I will likely never make Gold so can only try and get row 1 at T-72 if it is still unoccupied).
