Seattle–Seoul Made Simpler: Alaska Unveils Nonstop Flights with Limited-Time BOGO

New Nonstop Flights from Seattle to Seoul Bring Exciting Deals

Alaska Airlines has launched a new nonstop flight between Seattle–Tacoma International Airport and Seoul Incheon, offering travelers a convenient and comfortable way to connect across the Pacific. To celebrate this new route, the airline is running a limited-time promotion that includes special deals for both cash fares and award travel. The service is operated on a Boeing 787-9 Dreamliner, providing modern amenities and a long-haul cabin experience right from the start.

For the next three days, Alaska is offering a Buy One, Get One (BOGO) deal on the Seattle–Seoul Incheon route. This means that if you purchase a paid economy fare, your companion can fly for just the taxes and fees. Additionally, there's a special award pricing option starting at 20,000 points each way in the main cabin. These promotions are available for travel from September 12 through December 15, 2025, but you must book or purchase tickets by Friday, September 12 to qualify. Availability is limited, so it’s best to act quickly to secure the best rates and seat selections.

Understanding the BOGO Promotion and Award Options

The BOGO offer allows both travelers on the booking to earn Atmos Rewards points and status points on the paid ticket. If you choose to use points instead, the reimagined Atmos Rewards program still lets you earn elite credit on award travel. You will receive one status point for every mile flown on an award itinerary. For the Seattle to Seoul segment, which covers roughly 5,200 miles each way, this translates to 5,200 status points per direction for an award traveler. Regular points can be used toward future redemptions, while status points help track progress toward elite tiers and milestone perks.

Flight Schedule and Aircraft Details

The new Seattle–Seoul Incheon service operates five times per week, making it easier for families, friends, and business travelers to connect across the Pacific without the need for layovers. The route uses Hawaiian Airlines’ long-haul Boeing 787-9 Dreamliner, known for its comfort and modern features. The aircraft offers 34 enclosed Business Class suites with lie-flat seats, privacy doors, 18-inch HD screens, and wireless charging. The main cabin also includes a modern entertainment system and generous overhead bins designed for today’s carry-on luggage. Alaska plans to add Starlink Wi-Fi to the aircraft next year, enhancing long-haul connectivity.

Why This Route Matters for Seattle and the West Coast

Alaska Airlines continues to position its Seattle hub as a global gateway for West Coast travelers. The new nonstop access to Seoul strengthens this role, allowing passengers from dozens of cities within Alaska’s network to connect through Seattle and continue to Incheon the same day. The airline highlights that Seoul is not only a key business market but also one of Asia’s most dynamic and visitor-friendly capitals. Once in Korea, travelers can link to additional Asian destinations through partner airlines, creating flexible itineraries without the need to backtrack to other hubs.

Timing for a Major Korean Holiday

The inaugural season of the Seattle–Seoul route coincides with Chuseok, Korea’s Thanksgiving holiday, which falls in early October. This is one of the country’s most significant holidays, marked by family gatherings, bustling markets, and vibrant city celebrations. If you’re planning a fall visit, expect busy travel periods around the holiday and consider booking hotel stays and intercity transport well in advance. Outside of peak days, autumn weather in Seoul is typically mild and ideal for exploring neighborhoods like Insadong, Ikseon-dong, and Myeongdong.

Future Dreamliner Plans for Alaska

This is the first international route from Seattle operated by a Boeing 787 for Alaska Air Group, and more long-haul routes are already in the pipeline. The airline plans to introduce the 787-9 on its Seattle–Tokyo Narita route starting January 6, 2026. Next spring, Alaska will also debut 787-9 service from Seattle to London and Rome. For frequent flyers, this means more lie-flat options out of the Pacific Northwest and a consistent premium product across both transpacific and transatlantic flights.

Booking Tips Before the Sale Window Closes

If you're interested in the BOGO deal, search for multiple dates within the promo period to find the best fare pairings. Travelers using Atmos Rewards points should compare off-peak days to stretch their balances further. Consider mixing cash and points for different legs of the trip to fit your schedule better. Check seat maps early, as lie-flat suites on the Dreamliner are highly sought after. Also, keep an eye on baggage rules and seat selection fees to understand the true cost of your trip across different fare types.

Final Thoughts

Alaska’s new Seattle–Seoul nonstop flight provides a fresh long-haul option with compelling launch offers. Whether you're looking for a companion fare or a low-point redemption, booking within the three-day window is the best way to secure value for travel through December 15, 2025.
