With the merger, it's been a lot more difficult on MSP-ATL. Used to clear on a battlefield on this flight on a weeknight, but now with NW Plats in the mix on higher fares, I've been double digits down on the upgrade list lately.
Fuller F flights have been rare for me lately. I did ANC-MSP on Sunday and got the upgrade on an award ticket, and they cleared AS MVPs into F (who are lower than DL/NW Silvers). MSP-FAI on Friday had more empties in F than fulls. I had 3 flights the previous weekend (out of 4) where non-revs cleared into F; my trip before that had non-revs in F on all three flights (MSP-CVG-LAS-MSP over Memorial Day), and my trip before that (MSP-ATL-MSP for Greasy Spoon DO) had nonrevs in F on both those flights.
