You can't book an "Open" future cruise on the sister company. We tried that
on the Oasis. The consultant onboard said it could be done, but when we
tried to book a celebrity cruise later, they told us that an "OPEN" booking
could only be used on the cruise line that made the open booking. I'm not
sure if we still have one open booking on RCI available or not.

You can always do the "other" route... book a firm booking as far out as
you can, and then shift it later. The person on a Celebrity ship
suggested doing that one time.
