Booked 4 * J CX Savers BNE-HKG in early Feb this year (as part of the QF seat release) for travel on 27 Dec (departing 00:40). Somehow, I never booked domestic SYD-BNE awards to get to BNE when there was plenty of availability, at least on AA miles with free cancellation. At that time, we were not sure if the trip was happening or not.
Now that we confirm we are going, tickets for SYD-BNE on QF/VA are very expensive. After pondering Rex/JQ, I ended up paying ~$975 for 4 of us for SYD-BNE on VA Y departing 9am on 26 Dec, to ensure that we make the CX flight in time and not miss connection to HK. Whilst there were awards available on 25 Dec, we could not fly on that day.
I even thought of booking QF so that I could get luggage checked through to HKG, and possibly access to QF Dom J lounge at SYD. But QF is even more expensive than VA so decided against it.
I even booked a day room at Pullman Brisbane Airport to kill time as I really don't know if much of Brisbane opens on 26th Dec to make Brisbane sightseeing worth while.
Lessons learnt, better book all components of flights early if possible to secure awards.
