Keep in mind that per diems are very high in Italy! Its easily another 500 Euros a month and you now have the chance of becoming a captain very fast. With LH mainline you will also have a net income of about 3.000 to 3.500 Euros the first year, so it is not much of a difference in the beginning. And as I recall it, one of Alitalias problems was the high costs of its pilots...
