Just made 10 bookings with all 10 showing up booking management. However, when I clicked "see/manage" on one of the bookings then "Passenger information", for all of the passengers I've booked the "Frequent flyer card" collumn has a link that states "Add number" rather than displaying the Iberia card number.
I entered in the Iberia card number for each and every passenger on the 10 bookings which also showed up in the booking confirmation page. Should I be concered about this?
