Thanks folks for the insight. I was able to locate the ticket numbers, so it appears I'm good.

I suppose the additional hope is that they swap the A330-200 with a -300; not sure how often IB does that. 2 out of the 3 flights that week are currently sold out. Sounding selfish but a bigger bird with an expanded business class would certainly be nice so I can get everyone seated together, and bring in some additional revenue it seems like.
