I've got a mate who's been there about a year now who went to EI from another well known UK airline in which he was captain and went direct SFO.
He says training was good, company is good, although just like any other airline job. All positive stuff.
Captain's he has worked with have been welcoming of his background and experience.
He does get the odd overnight places, even being on the 320. He's Dublin based but gets moved all over the show between, Belfast, Cork and Dublin with the odd overnight in London too.
Regarding the salary, I haven't spoke exact figures with him, but he says it's fantastic at the moment as he gets paid in Euros and the pound is so weak.
