You should take the offer - if somebody else hasn't already taken it.

I'm struggling to understand that.
Why would you be unable to add your FB number? Is it because you have a Delta Skymiles/ITA Volare/some other FFP already attached to the booking?
And I don't see why changing/adding an FFP number would cause you to lose your seat assignment in Premium Economy....
