I've booked multiple Airbnbs through the BA estore recently (forgetting to do some that way, of course, but certainly not all) and none of the Avios have come through. Previously they used to arrive beforehand or within a few days after the booking. Does anyone have any idea what I have to say to BA to get the Avios? Unlike, say, purchasing from John Lewis or M&S, I never get an email confirmation that the Avios transaction has gone through/been logged.
