So I booked a 5 day trip to LHR from SFO with spouse over Thanksgiving to do theatre and shopping. (Grandkids all at in-laws). I booked D-fares so as to use my SWU's to elevate to the F cabin. Spent good money ($6K per tkt). Seats and all are worked out, but the booking code shows the dreaded "ON".

Does this mean I will have to call afterward and cajole and plead for the agent to change the travel date, etc., to get the flight to credit on the MP program? Anybody know?

I've been doing this on all reservations made prior to the March 3 meltdown. But the new ones that I've had upgrade on have been booked in "R". I don't mind participating in relentless struggles, but this is getting old, n'est pas? One would think they would stop with the "ON" booking codes.
