Route notes
Why this routing works
This 4-week itinerary is built as a multi-stop loop from Dallas to Istanbul, onward to Taipei, back through Istanbul, then on to Berlin before returning to Dallas. The sequencing uses Istanbul twice: first as the entry point between North America and Asia, then again as the return bridge back toward Europe before the final transatlantic leg home.
From a ticketing standpoint, this is structured as a single multi-stop business-class itinerary rather than separate round-trips. That approach keeps the route ordered across three major stop points and can simplify a trip that moves from North America to the Middle East, East Asia, and Europe within one month.
With an April departure in the apr-jun season, the timing fits a compact four-week plan where each stop is part of a forward-moving routing rather than a backtrack to the origin. The repeat Istanbul stop is the key logistical feature of the trip, linking the long-haul sectors in a way that connects Dallas, Taipei, and Berlin within one continuous ticket.
