I believe you have to set them up as "Beneficiaries" if they aren't travelling on the same booking as the IB+ member.
Since this promo appears too good to be true, it's worth keeping in mind that Iberia might just decide it made a mistake or magically come up with new T&Cs. This is the kind of promo I'd expect from an AirBerlin or Alitalia on its deathbed...
That's the worry with things that seem too good to be true. IAG also has recent history of "correcting" slip-ups.
