I have booked numerous flights using GGL redemption over the last few years and have always received tier points and avios points on the booking. Recently I booked a long haul redemption flight in 2 separate bookings - my husband and kids got avios points and tier points on their booking but I didn’t on mine (made 2 days later). I had assumed that they had made an error with my booking but you seem to be suggesting that the opposite is true and I’ve been lucky in the past.
