Thanks Cholula.
I am so sick of my $700 L class fares to MSP with very low chance of upgrades. I probably will take NW for my future flights to MSP. When I take NW and credit the miles to DL, does DL or NW receive the money for the flight? (Sorry to ask an unrelated question, but I didn't want to start a new topic that would probably just get 1 reply).
