Agreed RAT 5. When VW got caught out, they started to fire people and the top people resigned. We should expect to see that for, it does not matter what caused the problem - the problem happened and cannot be excused away.
Look at what Samsung did when their new phone was a disaster? Recalled, stopped production and made significant apologies. Thus far - BA has done nothing and it is well reported in the UK media that the group CEO (Walsh) was absent and that the BA man (Cruz) just emphasised that he would not resign. As I have said before in this thread, the first to be booted should be the IAG Group IT Director.
