Non Rnav,
Why indeed! I'd say it has more to do with their language problem. Very few of them must be really ashamed as they are so self isolated that they have very little knowledge of the outside world and so are led to believe that theirs is the "normal" way of running an airline. (Yes, they pretend they run it).
Another possibility is that no Iberia pilots would dare to speak up. In fact their union is so strong that very few of them would ever dare to dissent or take a stand against the instructions given by it. I wonder what percentage of them fully understand the demands or the implications of their industrial actions, yet they show an enviable determination to demonstrate their corporate muscle.
Anyhow, does anybody know what their current demands are and what the likely prospects are?
