Route notes
Why this routing works
This multi-stop itinerary starts in Calcutta and flies to Dar es Salaam, where the schedule is anchored by 27 nights. From there, the ticket resumes in San Francisco after an overland break, then continues with a simple West Coast loop to Los Angeles and back to San Francisco.
The structure matters here: the overland gap between Dar es Salaam and San Francisco separates the long-haul segment from the domestic USA flights, which can make the overall ticket more flexible for travelers who do not need every mile flown on one continuous path. The routing then finishes with an open-and-close pattern in the same US gateway, keeping the final segments straightforward.
With a total trip length of 4 weeks, most of the timing is concentrated in Dar es Salaam, while the US sectors function as shorter follow-on flights. In economy class, the sold price range for this itinerary was $1,730 to $2,265, with departure in July within the Jul-Sep season window.
