Route notes
Why this routing works
This round-the-world itinerary runs east from London to Singapore, continues on to Auckland, then turns back through Hong Kong before returning to London. With four flown sectors over three weeks, it spaces the long-haul flying across the trip rather than stacking back-to-back intercontinental returns.
Using London as both origin and endpoint keeps the ticket structure straightforward while still linking Southeast Asia, Australasia, and East Asia on one fare. The mid-trip progression from Singapore to Auckland sets up the longest southbound sector before the routing bends north again to Hong Kong for the final transcontinental return.
March works well for a compact three-week plan like this because each stop is connected by a direct onward sequence with no surface gaps or open-jaw breaks to manage. That keeps the timing simple: each city leads directly to the next, and the final London leg cleanly closes the loop.
