For reaccommodations, I've always suspected that "I" was accommodated in premium cabins above others ticketed using upgrade instruments booked into C, A, X, or R rebooking priority. Perhaps someone with more first hand experience can confirm that.
Do instant upgrade tickets always book into I class? I got a deal from SFO-JFK-MIA-MGA that booked into I class for business. However when I went to purchase the actual tickets there was three columns: Instant Upgrade, Business Special, and Business Flexible. I purchased Business Special, so I guess I would still have higher priority than a Y-up fare?
