Very little cockpit commonality between any A300/A310 and the A330, unfortunately.
A pity there's no 'A325' a 310-sized A320/A330!
A321 is too small to offer much - and A330 is rather big if your Dear Leader insists on having little war-ettes in different parts of the world all the time. A bit difficult to have half an A330 in the UK and the other half in Iraqistan....or providing Bennyfit to the Fuerza Aerea Malvinas!
