Been getting more upgrades than not, but this is the closest to departure in a long time.

5/24/23
AS 3358
LAX-PDX
upgraded at T-30 min

it was showing 5 F available yesterday with me as 3rd on the list. Then F became unavailable and it was Y5. I was hoping they closed F and were going to push people up to F as they sold the Y seats. They did, but waited til the last minute- looks like 4 upgraded at start of boarding.
