Route notes
Why this routing works
This multi-stop routing splits a three-week trip across two US cities, with the shorter stay placed first in Washington DC and the longer stop in San Diego. That sequencing keeps the itinerary moving east to west within the US before the return to Adelaide.
On one ticket, the plan covers the outbound transpacific journey, the domestic US connection between Washington DC and San Diego, and the final return to Australia. With 4 nights in Washington DC and 17 in San Diego, the timing is weighted toward a longer second stop rather than evenly dividing the trip between cities.
For an October departure, the structure is straightforward: arrive in the eastern US, continue onward after a brief first stop, then use San Diego as the main stay before the final long-haul sector home. The result is a clean open-and-close routing without backtracking between the two US stops.
