less than 35k points here, so it's not targeted to those with big balances. Perhaps target is those who have done JASAs before?
Or perhaps the arcane mysteries of QFF marketing are not for mere mortals to decipher, and depend on phase of moon, chicken entrails, last Saturday's lotto numbers, and whether the water goes clockwise or anticlockwise down the drain on the equator.
To further the speculation ..
There is three people in my household, including two QC members who are both close to silver, although at the moment all 3 of us are NB's. I was the only one to get it.
The only thing that would differentiates me from the other 2 is perhaps that that I do have a fairly high points earn rate in comparison to how often I actually fly (not all that often obviously) - mainly care of about 100k points a year from the banking category. My points balance is sitting at about 120k, compared to <50k for the other two. That, and while we also tend to travel as a group of three, it isn't uncommon for me to book the flights for at least two of us (and purchased both the QC memberships) -- perhaps something relevant if they are tracking spend per person against credit cards they've matched to particular FF profiles as part of perhaps trying to track influence?
None of us have ever done JASA's.
Two of us did a regular award flight just last week under separate bookings (1 QC, 1 not). Interestingly on that flight we noticed two radically different seating maps being presented during seat selection (the one I was shown by far being the better of the two) and I was offered a transfer to an earlier flight by the check-in machine at the airport although the other person was not. (Actually despite spare seats on the seat map 20 hours out online, my travel companion couldn't change his seat at all, even after calling the call center who gave him some speil about some 'initiative' which locks the booking down to all but airport check-in, or some such double-dutch that didn't make much sense at all).
They could be conducting some 'tests' on various target groups to see who responds and gather intel? Or it could be the likes of the same algorithm that offers some people better seat maps and flight transfers despite there being no status difference, possibly attempting to make guesses as how valuable you might be by comparing your overall spend to peers, perceived influence over the travel habits of others, etc? Or, it could indeed by related to last Saturdays lotto numbers - although I suspect there is something a little more considered to it!
