Cagliari is a well known "nightmare airport" because of its extremely poor ATC.
You get there and ATC won't tell you what approach to expect,afterwards it's not uncommon to have 2 or 3 different approach clearencies or runway changes depending on outbound traffic (which has precedence on landing aircraft???) , negligeable wind changes or military traffic operating in a closeby airport.
On top of everything italian ATCO's are not allowing pilots to shoot visual approaches (because of some pathetic union action against a judicial settlement in which a controller was convicted) having them flying the full instrument procedures even with 10.000 miles visibility and zero traffic around the field unless an emergency situation arises as in the above event.
The above incident is just another example of the very poor and unsafe approach the italian ATCO's are showing towards their job.
If the authorities are concentrating on "urging better fuel policies" they are missing the point: pilots base their planning decisions on standard procedures applied across the globe but can't really cope with a place where most things happen outside any internationnally recognised standard.
