Somewhat obscure question...
Trip was booked initially with all legs DL-coded but one leg on AF metal. Now, due to a schedule change, I was able to switch that one AF-operated flight to a DL-operated flight.
I'm assuming this will mean Accelerator treatment for all legs. Can anyone confirm? Trip is on 12/31/21 and would push three family members into the next medallion tier if Accelerator works.
Thanks FT!
