Pesonally, I would wait till project Sunrise starts before making any major overseas travel bookings, if wanting to fly QFi.
Or till things settle down, like for eg, if and when CX has more flights around the world, for any major plans, eg, me flying CX (ADL - HKG - Tokyo/CTS).
ADL airport does say it looks forward to CX coming back to ADL
Right now, airlines are still coming out of covid, or corporate restructures, the former AirItalian into ItaAir for eg.
