Was booked in F QF redemption on EK in early August SYD-AKL-DXB-LHR. Now it seems to be changed, with no notification. Somewhat disappointed at losing an EK F sector and replacing with QF J. We had booked a car from home to SYD as EK allow this. Should we get any miles back and a replacement car or are QF allowed to downgrade a partner booking without compensation?
