No. The BCal route went a long time ago and BA did not serve SAN for years. BA launched this as a new route about three years ago.
I think US based posters are looking at this the wrong way round. If you live in San Diego and want to go anywhere in Europe, BA offers a good choice of destinations with easy connections without the trek to LAX. Conversely, BA will be the easiest routing from Europe for many Europeans. Hence high loads.
CLT may have high loads at present but would a BA flight increase pax numbers anything more than marginally? If you share the same numbers across additional flights, revenue is poor.
BA would surely look for more underserved destinations like SAN, than go head to head with AA at CLT.
