I saw SV schedules their A332 on the SVO-CUN leg. I know that DL have scheduled their A330's on DTW-HND for A332's. For A333's I know that US scheduled the 333 on the ATH route. What would currently be the longest A330 flights today?? References about the SV flights and DL flights to HND from the following existing thread.
