I'd love for BA to operate flights to lax and bkk etc from MAN but they dont. main reason being as had been said on other posts on this site. London does not have a big enough catchment area for all of ba's flights so they have shuttles connecting in. BA have some sort of idea that lh out of anywhere other than lon is a bad idea which is why the only lh outside of lon in man0jfk which is always under threat of being cut.
