Route notes
Why this routing works
This 28-week economy itinerary moves in a clear westbound sequence from London to Bridgetown, then through Miami and Seattle before ending in Melbourne. The stop order breaks the trip into manageable long-haul stages rather than clustering all the longest flights together.
Bridgetown carries the first extended stay at 19 nights, followed by a short 1-night stop in Miami that works as a simple midpoint between the Caribbean and the US West Coast. Seattle then anchors the second long stay at 16 nights before the final transpacific leg to Melbourne.
As a multi-stop ticket rather than a round-the-world loop, the routing is built to finish in Australia instead of returning to the origin. That structure suits a trip where the timing is spread across several months and the longest sectors are separated by substantial ground time.
