I have received the 50% Status Credit offer email this morning as well.
I am NB, 210 SC with an anniversary approaching on Jan 31, 2017 (and delaying anymore QF flights until Feb, as was recently declined a status challenge, no harm in asking though.)
I have some forward bookings made previously, and have been flying quite bit in the last few months.
I did call QFF call centre to ask if there happened to be an email coming for Bee-Jnr and was advised that it was a random targeting, which is a bit of a shame, as I'd have booked her onto some more of the flights that I'll be taking in the next few months if she was to receive the offer too.
