heard that DUD/ZQN/DUD flights aren't going that well, but rest are doing very well, so they may adjust the DUD/ZQN flights accordingly.
DUD/ZQN is a very short sector or 3 hour drive ?
This sector might only work if someone was flying DUD/OZ. DUD/OZ fares are usually significantly cheaper than ZQN/OZ fares.
Sometimes AUD$300-$500+ difference per person, which is significant, especially if number of members of family involved & many people on tight budgets these days.
