Well, I believe the 744 I'm taking ORD-FRA on December 21 (booked in June--long story) does not have Y+. I deduced this because I got row 36, and I know I didn't pay full-fare Y.

Is it reasonable to think that some (if not all) of the 13 744's would have been converted to have C+/Y+ by then? If my plane has been converted, would my seat assignment be moved to accomodate people who paid for Y+?

Thanks,
Lawrence
