I got credited with miles on a roundtrip award flight on a European airline early this year - it was only an inter Europe hop so there were not many miles involved. I dutifully posted the details on Flyertalk but was asked to remove the post by a couple of board members - which I did.
Domestically I once flew SFO-MSP-LGA on NW crediting to my AS account. In MSP I was able to use an MVP Upgrade on NW and I got credited twice for the flight from MSP to LGA for some reason.
Often if I do something that requires supervisor override at the airport or on the phone this changes the booking class up to full Y. On a recent East coast trip I asked to change flights to an earlier day because I was worried about a snow delay - this required a supervisor override and was done as a courtesy for no fee (I felt I was helping them out in a sense by easing pressure on a day of disruption). The resulting flights posted as Full Y - had I known at the time I would have spent the (minimal) miles for an upgrade!
