the question relates more importantly to feeding our NATIONAL ECONOMY though
But BA aren't a nationalised industry, so their responsibility is to their shareholders. I think you'll find they will only play the 'national interest' card when they want something off the Government.
In general terms they will have an interest in the health of the national economy, on the basis that the richer the country is the more profitable they are likely to be, but feeding our National Economy is probably not top of the priority list.
