Route notes
Why this routing works
This 3-week multi-stop itinerary uses a simple westbound sequence from Key West to Sydney, onward to Cairns, then across to Lihue before returning to Key West. Keeping the two Australia stops together reduces backtracking and makes the long-haul structure easier to ticket as one continuous journey.
With 7 nights in Sydney and 9 in Cairns, the schedule gives a balanced split across Australia before a shorter 6-night stop in Lihue. That pacing works well for travelers who want longer stays rather than frequent flight changes, while still fitting the trip into a three-week window.
Ticketed in premium economy, this routing sits in a quoted range of USD 1,219 to USD 1,590. Departing in July, it is structured as a multi-stop itinerary rather than a simple round-trip, which is useful when the goal is to link multiple islands and long-haul segments on one ticket framework.
