For me...
1. Booked 10 one way flights on 24th of June.
2. It was a brand new Iberia account and was subsequently locked.
3. Emailed documentation on Tuesday, 25th of July at 3pm.
4. Just received an email (Friday, 27th July) to say 90k avois had been awarded.
5. Confirmed that 90k avois are in my account.
It seems I've been quite lucky in how simple it was?
