Route notes
Why this routing works
This routing uses a simple westbound sequence from Seattle to Denpasar Bali, then onward to Bangalore before returning to Seattle. With two long stays of 13 and 10 nights, it fits a 4-week plan without adding extra stop complexity or backtracking between regions.
As a multi-stop economy ticket, the structure is built around one open sequence across Southeast Asia and South Asia rather than separate round-trips. That can make timing cleaner for travelers who want substantial time on the ground in each stop while keeping the flight pattern straightforward.
A May departure places the itinerary in the April-to-June travel window. With only two overseas stops, this route is easier to manage than a larger round-the-world ticket, while still covering multiple regions on one booking and ending back where it started in Seattle.
