Route notes
Why this routing works
This 4-week itinerary is structured as a South Pacific loop from Chicago, starting with an overland arrival into Auckland before rejoining the flight sequence in New Zealand. From there, the routing stays efficient: Christchurch follows within the same country, then the trip crosses to Australia for Melbourne and Sydney before returning to Chicago.
The stop order reduces backtracking by grouping New Zealand first and Australia second, which is a practical way to ticket this region on one multi-stop plan. Keeping Christchurch ahead of Melbourne and Sydney also makes the trans-Tasman connection a single directional move rather than a repeat crossing.
With 4 nights in Melbourne and 6 nights in Sydney, the Australia portion is the most defined part of the schedule, while the overall trip length remains 4 weeks. In business class, this routing is well suited to travelers who want a more comfortable long-haul framework across the Pacific while keeping the stop sequence straightforward.
For October departures, the route works cleanly as an open-jaw entry into New Zealand followed by onward flights through the rest of the itinerary. As a multi-stop ticket, the value here is in combining the long-haul Pacific sectors and the regional links into one coordinated sequence rather than piecing together separate one-way flights.
