Pure and simple window-dressing for publicity and 'woke-ness'. An airline's job is to fly customers and freight from origin to destination safely ... and not to make a financial loss when doing so. What a waste of money for something that will be 'replaced' by something 'more appropriate' or 'more fashionable' in a few years time.
BA has a long way to come to reach its previous quality of service. This is not the way forward.
