It is precisely this familiarity with BAEC that led people to move their Avios over to BA instead of booking rewards through IB+. These aren't newbies, but people who have a reasonable understanding of the miles hobby.

Going forward, absolutely anybody who wants to fly IB but has a negative IB+ balance will simply use their BA account to earn miles. Not a single IB booking should be lost.
