Route notes
Why this routing works
This routing uses a short Seattle stop at the front end to set up the transpacific departure, then moves west through Asia in a clean sequence: Seoul, Penang, Hong Kong, Taipei, and Tokyo, before returning to Portland. The structure keeps the trip directional rather than doubling back between the same city pairs.
Within 4 weeks, the stop lengths are distributed unevenly in a practical way: 5 nights in Seoul, 4 in Penang, 2 in Hong Kong, 8 in Taipei, and 6 in Tokyo. That balance makes this a true multi-stop ticket rather than a simple open-jaw, with enough time in each city to justify separate flight segments while still keeping the overall trip compact.
In economy, this kind of Pacific circle works best when ticketed as one coordinated itinerary rather than piecing together separate one-ways. The fare range here starts at $1,997 and runs to $3,046, which frames the route as a budget-conscious long-haul plan with several East and Southeast Asia stops built into a single booking.
October departure timing places the trip in the Oct-Dec travel window. For a route with six flight sectors before the final return home, that timing and sequencing matter as much as the destinations themselves: the itinerary starts with a domestic positioning leg, builds through Asia stop by stop, and finishes with a straightforward transpacific return from Tokyo to Portland.
