Route notes
Why this routing works
This five-week economy itinerary moves west from Fort Lauderdale to Fiji, then continues through Australia before finishing in London. The pacing is front-loaded with longer stays in Nadi and Melbourne, which keeps the transoceanic sectors separated by substantial ground time rather than stacking the longest flights back to back.
Routing through Melbourne before Perth keeps the Australia portion sequential from east to west. That avoids doubling back within the country and sets up a cleaner final long-haul onward to London after a shorter stop in Western Australia.
With 8 nights in Nadi, 18 in Melbourne, and 6 in Perth, the stop pattern is built around three stays rather than rapid city-hopping. In a January departure window, that structure gives each flight leg a clear role in the overall progression instead of turning Australia into a series of tight connections.
As a multi-stop ticket rather than a simple round trip, the itinerary trades a return to the origin for an endpoint in London. That open-ended finish suits a trip built around continuous westbound movement across the Pacific and onward into Europe.
