Route notes
Why this routing works
This seven-week business-class itinerary is built as a continuous westbound sequence from Newark through Asia and on to Europe before the final return to Newark. It avoids backtracking by linking Tokyo, Osaka, Taipei, and Singapore in order, then continuing to Zurich and London as the European finish.
The early Tokyo-Osaka sector keeps the Japan portion on the same ticket rather than requiring a separate internal reposition later in the trip. From there, the routing steps south to Taipei and Singapore before turning northwest to Zurich, which helps organize the long-haul flying into a clear progression across regions.
With all sectors flown and no surface gaps, the plan is straightforward to ticket and easy to follow over seven weeks. London sits near the end as the final stop before the transatlantic return, giving the itinerary a clean closing leg back to Newark.
