I have noticed that DL230 JFK-FCO has been an A330-300 some days and A330neo other days, with no consistency. Looking ahead, it looks like it's an A330-300 through the end of December and then switches back to the A330neo. I am booked on 1/2/25 on this flight in D1 and am hoping it doesn't change to the A330-300. Does anyone have any insight as to why this is happening? Will there likely be an equipment change as it gets closer?
