Route notes
Why this routing works
This itinerary is structured as a westbound multi-stop ticket from Atlanta, using Los Angeles and Honolulu to break up the Pacific crossing before continuing to Sydney and Perth. From Western Australia, the routing then shifts to Europe with a stop in Milan, followed by the return to Atlanta. The sequence keeps the trip moving in one direction rather than backtracking.
With 3 nights in Los Angeles and 3 in Honolulu, the early part of the route turns the long-haul positioning into planned stopovers instead of same-day connections. The Australia segment is split between 4 nights in Sydney and 4 in Perth, which creates a clean domestic progression across the country before the long onward flight to Milan.
At 3 weeks total, the timing is relatively tight for five stop points, so the balance of short and medium stays matters. Milan has the longest stop at 6 nights, giving the final international segment more room before the return to the US. In business class, this kind of multi-continent routing is well suited to travelers trying to cover the Pacific, Australia, and Europe on one ticket while keeping each leg in a logical sequence.
