DL flies an international 763 (which means no wifi, but free movies) ATL/PDX. I've gotten upgraded on that one many times. Also occasionally MSP/PD but only on low traffic days. But as far as any other DL flight, never in several years now. BTW, DL cares less about AS 75/Gold/MVP, they are all the same thing to them - one group at the bottom of the list.
