On September 12, Hawaiian Airlines began operating a new long-haul route from Seattle to Seoul Incheon. The service is run by Hawaiian crews but falls under the Alaska Air Group, which owns Hawaiian Airlines. This move comes as the carrier plans to end its Honolulu-Incheon flights in November, partly due to limited slot availability at Seoul and a need to optimize aircraft use.

This new route marks Hawaiian and Alaska’s second long-haul connection from Seattle, following the launch of flights to Tokyo Narita in May. The companies have stated their intention to develop Seattle into a global hub. Additional international services are planned, including flights to Keflavik using Alaska’s Boeing 737 MAX 8s next year, and future routes to Rome Fiumicino and London Heathrow with Boeing 787-9 aircraft.

The inaugural flight was timed just before Chuseok, Korea’s Thanksgiving Day holiday. Hawaiian operates this route five times weekly with its 300-seat Boeing 787-9 aircraft. The plane features 34 fully flat business class seats equipped with privacy doors and 266 economy seats—79 of which offer extra legroom.

Originally, the airline had planned to use a smaller Airbus A330-200 for the route. That model would have offered fewer business class seats and a different seating layout in economy class.

Flight HA871 departs Seattle at 14:50 local time on Wednesdays through Sundays and arrives in Seoul at 18:35 the next day after an approximately 11-hour-and-45-minute journey; this will increase to up to 11 hours and 55 minutes later in the year due to seasonal winds. Return flight HA872 leaves Seoul on Mondays, Thursdays, Fridays, and Saturdays at 20:35 local time.

Market data shows that between July 2024 and June 2025 about 400 daily round-trip passengers traveled directly between Seattle and Seoul without connecting elsewhere. Only Tokyo had more direct traffic among Asian destinations from Seattle during that period. Delta Air Lines, Korean Air, and Asiana (now part-owned by Korean Air) already operate nonstop flights on this route.

Hawaiian/Alaska faces competition for local travelers from these established carriers but hopes that Alaska's strong presence in the Pacific Northwest will help attract passengers. Unlike its competitors, Alaska does not offer onward connections via Seoul; instead it relies on its extensive network feeding into Seattle for both passengers and revenue opportunities. Over a recent twelve-month period more than ten thousand daily passengers flew between North America (the US/Canada) and Seoul—many traveling indirectly from cities such as Houston, Orlando, Austin, Phoenix, Denver, or Portland.

With a scheduled block time set to reach nearly twelve hours during winter months due to stronger winds, this new service becomes Hawaiian's longest route—surpassing its previous record-holder between Honolulu and Boston (up to eleven hours eighteen minutes), which will be discontinued in November. Looking ahead to 2026, Alaska’s planned service from Seattle to Rome may take over as the airline group’s longest flight once launched.

Hawaiian Airlines was founded in 1929 as a full-service carrier with hubs at Honolulu International Airport and Kahului Airport.
