I followed step by step and purchased 10 one-way tickets in the form of round trips.
I have every intention to complete all of them in the order they were structured.
I was logged in on the tickets purchase. I then went back the next day and added my IB account again.
Haven't checked my account yet, as i had just gotten back from a 4 country 6 day trip (Europe + Asia) involving 8 flights (half of them long haul), but if I don't get any points from IB, I won't go hysteria and threaten to chargeback or take Iberia to court.
I had a lot of fun booking those flights.
