Route notes
Why this routing works
This 8-week itinerary uses a clear westbound sequence from Singapore to Phoenix, Athens, Kilimanjaro, and Zanzibar, then closes the loop back in Singapore. The stop lengths are weighted toward two longer stays at the front of the trip, with 22 nights in Phoenix and 18 in Athens, followed by shorter stops of 6 nights in Kilimanjaro and 7 in Zanzibar.
As a ticketing structure, this works well as a true multi-stop itinerary rather than separate round-trips, because it links North America, Europe, and East Africa on one continuous economy fare. Keeping Kilimanjaro and Zanzibar back-to-back is a practical regional pairing inside Tanzania and reduces unnecessary backtracking late in the route.
Timing also makes sense for an 8-week trip departing in June: the longer stays are placed earlier, while the final two Tanzania stops are shorter and easier to combine before the return to Singapore. With a sold range of USD 4,019 to 5,261 in economy, this is a complex but efficient long-haul routing across four regions.
