I recently flew on a DL-marketed flight operated by VS, ticketed on VS. As far as I can tell from delta.com, this should be eligible for MQDs, but unfortunately, the flight posted with the VS flight number, and no MQDs.

So far my attempts to contact Delta via email have resulted in unhelpful responses claiming that because it was a VS-operated flight, it does not qualify for MQDs.

Has anyone else had trouble getting MQD on DL-marketed flights not ticketed by Delta? Any suggestions on how to get this resolved (or am I wasting my time)?

Thanks!
