I was talking about short cycles as such (ie per sector), not a daily utilization.
Sure many aircraft doing 4 sectors a day and full rotation could be anything between 2 and 8 block hours in Europe which is by far lower than what A330 is designed for.
Anyway early production A330-300 in 2012 will be the same age as A300B4 was when conversions were started, so I guess we will see it soon.
