Priority Seating with MP Gold on One World flight using another FFP
I just booked an American Airlines domestic flight using my AAdvantage number. I have no status with AA, but I am One World Saphire with Marco Polo Gold.
I chose a priority seat upon seat select with the understanding the airline will reassign me if it is deemed I do not have priority or status.
Is it possible to have priority seating on AA because of my one world status even though I am using AAdvantage and not MP Gold as the FFP?
