The spouse hit 1mm yesterday PVR - DEN. It was exciting as I know how much effort goes into getting it. However, no acknowledgement, no note, no coin, nothing at all, there was a notification on the App, so I was surprised that the App did not notify the cabin crew or something similar. Neither of us are ever expecting to get to additional milestones as we are getting to the time that decades of travel has lost its joy. To top it off, there was supposed to be a wheelchair waiting as they have a hip surgery next Friday. Kind of a downer 1mm crossing flight. Still seems like its pretty hit or miss for recognition. We will see what comes in the mail.
