The result.
QF408 was distressed so transferred to QF10.
QF10 left 30 minutes late as passengers arrived late.
Arrived in SYD just as LA800 boarding started.
LA800 left 30 minutes late due to baggage handling difficulties but arrived at AKL only 10 minutes behind schedule.
LA801 running 2 hours late so transferred to QF40.
QF40 arrived in SYD in time to get QF419 to MEL as booked.
All in all an ok trip with biz class significantly cheaper than Qantas fares.
