Alaska Airlines New Routes: Seattle–Reykjavik & Seoul
Alaska Airlines new routes link Seattle directly to Reykjavik and Seoul, reshaping West Coast international service and partnership networks.
Alaska Airlines confirmed two headline international launches: Seattle–Reykjavik will operate on a Boeing 737 MAX beginning May 28, 2026, while Seattle–Seoul will resume using a Hawaiian Airlines-operated Boeing 787‑9 Dreamliner starting September 12, 2025. The carrier is promoting introductory fares and says it will expand codeshare connections with Icelandair for the Reykjavik service.
The Seattle–Reykjavik rotation on a narrow-body 737 MAX is notable because Alaska says it will represent the longest U.S. narrow-body flight, stretching the airline’s transatlantic reach without widebody equipment. Meanwhile, the Seattle–Seoul service runs through a partnership with Hawaiian Airlines, using the 787‑9 on the Asia-Pacific sector.
Why Alaska Airlines new routes matter
These moves strengthen Alaska’s footprint across both the North Atlantic and the Asia-Pacific from its Seattle hub. Expanded Icelandair codeshares add onward connections in Europe, while the Hawaiian-operated Seoul flights provide a Pacific gateway that blends both carriers’ networks and aircraft assets. Promotional fares are expected to drive initial demand and awareness.
- Alaska Airlines new routes: Seattle–Reykjavik (737 MAX) from May 28, 2026, and Seattle–Seoul (Hawaiian 787‑9) from September 12, 2025.
- Expanded Icelandair codeshares will improve transatlantic connections via Reykjavik.
- Promotional fares will accompany launch periods to attract travelers and build load factors.
Not all carriers are expanding: Hawaiian Airlines is reportedly cutting service to Boston, Seoul and Fukuoka, a shift that signals changing priorities for U.S. West Coast international connectivity and competition. Together, Alaska’s route additions and Hawaiian’s network adjustments point to a dynamic market for transatlantic and Asia-bound travel from Seattle.
For travelers, the changes mean new nonstop options and partnership-driven itineraries between Seattle, Europe and Asia — with aircraft types and launch dates now confirmed for planning and fare searches.
