Northwest is also offering introductory fares from Portland to Beijing, Busan, Hong Kong, Seoul, Shanghai, Singapore or Taipei for $379 each way, Bangkok for $404 each way and Manila for $494 each way.

Introductory fares are also being offered from other Pacific Northwest cities such as Bend/Redmond, Eugene and Klamath Falls, Ore., as well as Spokane, Wash., at slightly higher fares.

September 11 security fees of up to $10 roundtrip per person may apply and additional terms and conditions apply. For a complete list of terms and conditions, see below.

Customers currently holding tickets for travel June 10, 2004 and beyond on connecting itineraries from Portland or other Pacific Northwest cities to Japan and Asia will be able to change to Northwest's new Portland-Tokyo nonstop service without paying an administrative change fee, provided changes are made by April 30, 2004.
