Economy return from $1,399*
Premium Economy return from $3,499*
Seems to be plenty of seats still at these prices and looking at the seatmap the flight appears to have perhaps 10 people in all classes.
The normal SYD-JNB QF63 is still operating that day, so does that mean QF163 will return empty or will QF63 be cancelled?
