Yes I think this seems to be more an issue of a KTN not being enterable as some detail wasn’t matching. However as you say since this is a wholly AA operated itinerary I am still unclear why the details couldn’t be corrected on AA MMB before the date of the flight and the KTN entered there - I wouldn’t waste my time contacting BA if this had happened to me. I think the issue was this hasn’t been obvious to the OP.
