I, too, have no complaints regarding my experience as an FO. I had a few upgrades, a few generous reps on the Medallion line who didn’t need to be so kind, and generally nice service. I don’t ever remember getting thanked at the gate for being Silver though—that only seemed to happen once I hit Platinum and even then, it’s still maybe 70 percent of the time. (I mean, not that I need a verbal reminder of my status every flight...)
