I was booked on AZ from CPH to FCO yesterday.
The flight was cancelled and then re-instated, now operated by a British Airways ATP operated by a franchiser, SUN-AIR.
I can tell you the flighttime was almost 4 hours, but the service was the best I ever.
A lot of good food, ice cream, free drinks and a very service minded crew.
So watch out Alitalia, BA is out there!
