Route notes
Why this routing works
This itinerary is structured as a compact 2-week Asia multi-stop from San Francisco, moving westbound through Chengdu and Guilin before a longer final stop in Seoul and the return to San Francisco. The stop pattern keeps the China segment together, which simplifies the routing and avoids backtracking between countries.
With 4 nights in Chengdu and 2 nights in Guilin, the first half of the trip is paced for shorter stays, followed by 9 nights in Seoul as the longest stop. That sequencing works well for travelers who want the final city to anchor the schedule rather than splitting the longest stay across multiple points.
From a ticketing perspective, this is an economy open-jaw style multi-stop built around four flight sectors: San Francisco to Chengdu, Chengdu to Guilin, Guilin to Seoul, and Seoul back to San Francisco. Using a single multi-stop ticket for this order can be a practical way to lock in the full route in advance instead of piecing together separate one-way flights.
Timing-wise, an April departure fits this itinerary's 2-week framework cleanly, with the overnight long-haul segments on the front and back end and shorter intra-Asia flying in the middle. At a sold range of $2,165 to $2,834 in economy, the route sits in a price band that reflects both the transpacific flights and the added regional stops.
