I live in Melbourne. I have made numerous trips to Jo'burg over the last year. To do this I have to travel via SYD to take QF63. This is very frustrating, as the flight path SYD-JNB passes exactly over MEL. I can look down and see my home as I fly over! Why doesn't Qantas run this service out of MEL? Fewer overall passenger miles. Fewer FF points to dish out. Passengers saved the terminal transit hassle at SYD. More capacity at MEL, and easier transfer for transiting passengers.
