The logical response to this is "How will we know??" They have cut it back already from places such as PER and ADL and are down to one flight a day from MEL (excluding JQ) and BNE. SQ are cleaning up and have increased frequencies across the board.
CAPA had an interesting article on this last week and it basically concluded that SIN is a dead-duck for QF because they offer so few onward connections. This is an interesting outcome given 2 years ago AJ was proclaiming RedQ was probably going to use SIN as its Asian gateway.
I'll wait until 27/2 but at the moment it seems QF's Asian strategy is a shambles.
