Oh dear goldstone - you know so little about it all. What have the unions got to do with it??? As it was said BA acted on the advice of the Government not the Unions. The Unions deal with what goes onboard not where the airline fly to.
Perhaps it should be said that an extremist group tend to attack the nationalility of the airline (or Comapny) and not the nationalities of the people who work for it. If they see a 'Union Jack' Company they are not going stop and bother to see if their 'own' people work for it.
