@Smith,
Without entering into the discussion about the quality of the training in Ryanair
, I would like to tell you that another very important reason why Ryanair's pilots are well accepted by other companies is because they are easier to please
due to the fact that they come from an airline where they have to pay for everything and they are badly treated by their management...
It is a way for some of these companies to avoid to raise their conditions by showing to their own pilots how easy they can find plenty of pilots happy to work for them....
This is not speculation it is exactly what I have heard from one of those company's management guy.
