BA have just called me to discuss the Data Breach - I've made 9 bookings in the past 3 weeks.
I've made no contact with the GGL team myself, so the call was out of the blue.
They apologised etc, and when I asked about some sort of material apology (more out of curiosity than anything else), the lady advised me that the Loyalty Team would be in touch.
She had no timeframe for when that would happen, but advised that action was currently being discussed.
