Thanks for your reply. Much appreciated.

What still seems odd - and what triggered my question - was the fact that on the ATL-SRQ upgrade list, I was dead last - #9 of 9 awaiting an upgrade even after the cabin had been filled up. You'd think that with such a heavy concentration of Platinum flyers out of ATL, that there'd also be a heavy concentration of Golds and Silvers as well, and that at least some of those folks would have also been on this flight of over 100 passengers, in which case there would have been at least a few names lower in the queue than me. Seems statistically improbable that mine would be the last name on the list.

I'm not really that concerned about not being upgraded on this flight but rather more curious as to whether there might be something funky right now with how NW Platinum status is being handled on DL or if there are significant differences between how DL prioritizes the upgrades vs. how NW prioritizes them.
