Seattle-Tacoma International Airport (SEA Airport) stands out as a main entry point for travelers from around the world. Throughout 2025, the airport is adding several new direct flights and boosting its international presence. These new connections offer a smooth travel experience for people across the Pacific Northwest and help Seattle’s economy as more travelers, students, and workers arrive from many countries. As global travel picks up, SEA Airport’s expansion is turning it into an even bigger hub for international journeys.
SEA Airport: A Growing International Center
Right now, SEA Airport connects people to 33 international destinations and 94 nonstop domestic routes. A total of 36 airlines operate at the airport, bringing options for both business and personal trips. Some of the most popular international routes take passengers to Canada 🇨🇦, Mexico 🇲🇽, countries in Europe, and cities across Asia.
The increase in direct flights means less time spent on layovers and easier trips for everyone who lives in Seattle or nearby towns. Many travelers see SEA Airport as a smart choice because it is a gateway to other countries without unnecessary stops.
Arrival of New Direct International Flights
This year brings exciting changes for travelers using SEA Airport. New direct international flights are now a big part of the airport’s plans. These routes not only help locals leave for overseas trips but also encourage more visitors to experience everything Seattle offers.
Alaska Airlines Expands Its Service
On May 12, 2025, Alaska Airlines began a nonstop flight from Seattle to Tokyo Narita, allowing travelers to reach Japan 🇯🇵 with one easy trip. Just a few months later, on September 12, 2025, Alaska Airlines will also start flights from Seattle to Seoul Incheon, making the journey to South Korea 🇰🇷 straightforward.
These new flights are special for several reasons:
- The Seattle-to-Seoul flight will use Hawaiian Airlines’ Airbus A330-200 planes at first. Later, Alaska Airlines plans to use Boeing 787 Dreamliner jets for even better comfort and more advanced features.
- Alaska Airlines has said it wants to make Seattle “the West Coast’s premier global air gateway.” This means they see SEA Airport as a top choice for starting or ending international trips in the western United States 🇺🇸.
Analysis from VisaVerge.com suggests that bringing in more direct international service will make it even easier for people to travel to and from the Pacific Northwest, whether they are visiting family, starting a new job, or coming to study.
SAS Returns After 57 Years
Another exciting update is the new direct flight between Copenhagen and Seattle, offered by SAS (Scandinavian Airlines). This route begins May 21, 2025. After a gap of 57 years, travelers will once again be able to fly nonstop between the two cities on SAS flights.
- SAS will operate this route five times a week.
- These flights are scheduled to connect smoothly with 39 other SAS destinations across Europe 🇪🇺.
- Travelers going to cities outside Copenhagen can easily continue their journeys without long waits or extra flights.
This return of direct air service means families across the globe can reunite, and companies can reach European partners with fewer hassles.
Other Recent Additions: More Options Than Ever
In addition to the flights offered by Alaska Airlines and SAS, SEA Airport has seen growth in other nonstop international connections. In 2024 alone, travelers gained new options to fly directly to Toronto 🇨🇦, Munich 🇩🇪, Taipei 🇹🇼, and Manila 🇵🇭. By the end of 2025, Seattle will boast nonstop flights to 33 international cities in total.
Some of the newly added destinations in 2025 include:
- Copenhagen 🇩🇰
- Zurich 🇨🇭
- Seoul Incheon 🇰🇷
American Airlines is also considering a direct route from Seattle to Bengaluru (Bangalore) 🇮🇳, India, though the launch has been delayed multiple times since 2020. If this route is added in the future, it will further help students, workers, and families with roots in India.
Why Direct Flights Matter
The introduction of these new direct flights is not just about convenience. They have a big effect on Seattle’s economy and quality of life. Here’s why nonstop connections mean so much:
- Easier travel for students coming to study at local universities, or for workers starting new jobs in the region.
- Quicker business trips, making it possible for companies in Seattle to connect with international partners and clients.
- More tourism, which helps hotels, restaurants, and shops in Seattle and surrounding areas.
- Increased cultural exchange, as residents and visitors share their traditions, foods, and languages.
Local business leaders and tourism experts say these new flights will lead to more jobs and help Seattle companies grow. They point out that it takes less time and causes less stress to reach key business centers when you can fly direct.
For international students, direct flights mean their journey to Washington state is smoother, with fewer delays due to missed connections. This makes the region more attractive for education and skilled migration.
Meeting Strong Demand in a Changing World
These new routes are arriving at a time when more people want to travel internationally for personal and business reasons. After the COVID-19 pandemic, demand for both recreational and business travel has come back strong.
- Many travelers now want to visit family abroad or have “heritage travel” experiences—visiting the countries where their families or ancestors came from.
- International business connections are growing fast, and direct flights help companies operate in different time zones more efficiently.
- The need for easier trips to and from emerging markets is bigger than ever.
An example of this trend is the Seattle-Seoul route, which was described as “one of the most requested international routes without direct service by a U.S. carrier.” Alaska Airlines is meeting this demand by filling an important gap in travel options between North America and Asia 🇨🇳 🇰🇷 🇯🇵.
Getting Ready for the World’s Biggest Events
Seattle’s growing list of destinations also comes just before an exciting global event: the city will host matches for the FIFA World Cup in the summer of 2026. With thousands of fans and workers coming for the games, the extra flights will help Seattle handle the rush.
- King County is expected to earn about $900 million from hosting World Cup events.
- Direct international flights will make it easier for soccer fans from Europe, Latin America, and Asia to reach Seattle.
- The added convenience also means visitors can spend more time watching games and enjoying local sights, rather than dealing with flight delays.
The timing couldn’t be better. As Seattle becomes a world stage for sports, culture, and business, extra flights make sure the city remains connected and welcoming.

Looking at the Future of Air Travel
Alaska Airlines and other carriers are making large investments to support bigger, more fuel-efficient airplanes like the Boeing 787 Dreamliner. These planes can fly longer distances in comfort, opening up the possibility for even more direct flights.
SAS’s renewed connection with Copenhagen allows for one-stop journeys to dozens more cities across Europe. People traveling for business, study, or tourism now have a much bigger world to explore with fewer hassles.
