Spare us the left versus right.
Alitalia is one of many airlines who struggle. 457 visas remain the refuge of the aviation HR scoundrel.
To suggest that 1,000 pilots will solve the demographic shortage may well be helpful to IR/HR practitioners, but will not address the shortage.
As to Alitalia specifically, the company I keep are very interested in a number of carriers with varied ownership structures listed and traded on the world's stock exchanges. They are both the older and newer style with their various capital structures.
