The problem is that although Mixed Fleet is not represented by BASSA it is still Unite and still the same bone headed officials behind the scenes.
As others have said the equally bone headed managers in BA could not see the opportunity to improve things for the new, keen cabin crew incrementally and thereby diminishing the poisonous influence of their 'neighbours' in BASSA.
With the wanton destruction of the airlines reputation and USP by the new Iberia management I don't see a great future.
