Taiwanese carrier Eva Air has joined Southwest's budding list of international partners.
Interline itineraries connecting flyers to Eva via Southwest's U.S. gateways in Los Angeles, San Francisco, Seattle and Chicago O'Hare are now bookable through the GDSs, Eva Air's website and third-party sites.
Southwest did not say when booking would be enabled through its own sales channels.
All of Eva's U.S. service flies to Taipei.
Eva is Southwest's second Taipei-based interline partner, joining China Airlines. Those interline itineraries connect through Los Angeles, San Francisco, Seattle and Ontario, Calif., for travel beginning Jan. 26.
Icelandair became Southwest's first interline partner early this year.
Update: This article has been updated to reflect that bookings are available through the GDSs.
