PhilD I may not have made my view quite clear, for which I apologise.
Of course BA shouldent have to pay for ongoing flying once they have finished with her, however I do believe that they have a duty to pass her on as they were given her (for free) originally - i.e. in flying condition, and financially unencumbered. In short, for Free.
They have indeed invested heavily in her, and also done extremely well by her, both financially and (even more so) in marketing terms. Well done BA for this, but I am sure that most would share my view that BA, having secured her commercially for themselves whilst others sought to operate her, should not seek to gain by her 'sale'.
Speaking as a significant shareholder in the company, I take the view that the company will be better served in the public eye by being magnanimous and making it possible for her to remain flying.
