Well, when I booked it I didn't know I was going to get NW codeshares. I asked for DL 72/DL719, booked via phone so I could use the cert -- had no idea, until after it was booked, that the agent actually booked it as a NW codeshare.
Anyhow, apparently I'm not screwed. I called back last night and spoke with another agent, not sure if she did anything or not but she said "I have you on the upgrade list for both flights." This morning I'm showing First (R) for both the outbound and return... not sure if it matters or not, but it did get ticketed as 012.
