Flown 4 QR sectors in R & F class out of 2 sectors 8 days ago, the other 2 sectors 3 days ago ... none have posted. On the other hand, friend of my flying exactly same flights, class, and dates, have already received all 4 sectors credited to his QF account, consistently credited 3 days after flight was taken. This tells me it is a BA deficiency, not QR.
