Air New Zealand has just announced $300 (Economy) & $600 (Business) discounts to the USA. From what I can see, the best value is once again Los Angeles, with all-inclusive fares at just over $900 from the east coast of Australia. There are plenty of seats available at time of posting. Happy travels :)
