”The A330 Common Type Rating allows pilots to transition from A330 to A350 aircraft in only eight days without full flight simulator sessions. This enables carriers to use a single-fleet flying concept with a pool of pilots qualified for both aircraft, providing increased scheduling flexibility and mobility.”
Not that hard to go from 320 to either A330 or A350 either. I believe Airbus claims an 11 day transition to the A350 and only 7 days for the A330.
