Two of the TC A330s are worldwide fleet leaders on hours flown and were mid way through the Airbus life extension programme in which they were the first aircraft to be enrolled. Although they have plenty of life left yet, it would be a brave new operator getting into the A330 for the first time to take these particular aircraft on, unless you knew exactly what you were doing and had the engineering specialist expertise to do it. That’s not to say Jet2 couldn’t or don’t, but it is sensible not to rush into such things.
