SAS is increasing flights to two major Delta Air Lines hubs as part of an extensive expansion of its summer 2027 schedule. The Scandinavian carrier will increase services from Copenhagen Airport (CPH) to Atlanta and Seattle, strengthening connections with its US partner while adding capacity across a total of seven intercontinental routes. The November 10 announcement also includes larger Airbus aircraft, more than 20 European and Scandinavian route enhancements, and two new destinations. The expansion follows SAS's transition from Star Alliance to SkyTeam, which has brought it closer to Delta and Air France-KLM.

Both changes restore previously offered frequencies: SAS launched Atlanta flights in June 2024, shortly before its formal move to SkyTeam, wasting no time connecting into the alliance's busiest global hub. SAS also operates nonstop services to three other Delta hubs: Boston, Los Angeles and New York-JFK. Delta Hub SAS Nonstop From Previous Frequency Summer 2027 Atlanta Copenhagen 5 weekly Daily (+40%) Seattle Copenhagen 4 weekly 5 weekly (+25%) Boston Copenhagen Daily No change Los Angeles Copenhagen Daily No change New York-JFK Copenhagen, Oslo Daily No change SAS' partnership with Delta formally began in September 2024, just days after joining the alliance, with a revised codeshare agreement. The expanded agreement covered 150 destinations in North America, as well as around 50 destinations in Northern Europe. The cooperation increased again in April 2025, with both carriers adding more connecting opportunities and reciprocal loyalty benefits. Paul Verhagen, Chief Commercial Officer at SAS, said at the time: “We are thrilled to continue expanding our partnership with Delta, enhancing travel options between Scandinavia and North America. As a proud new member of SkyTeam Alliance, our collaboration offers great opportunities to provide seamless connectivity and benefits across our global network." The relationship is expected to deepen further through Air France-KLM's proposed acquisition of a controlling 60.5% stake in SAS. During its November 5 earnings call, the group's CEO Benjamin Smith said the group now hopes to complete the transaction in the first quarter of 2027, subject to European Commission approval. This could eventually support SAS joining the existing Delta–Air France–KLM–Virgin Atlantic transatlantic joint venture. SAS Expands Five More Long-Haul Routes And Deploys Larger Airbus Aircraft Credit: InsectWorld | Shutterstock Beyond Atlanta and Seattle, SAS will increase Copenhagen flights to Tokyo Haneda Airport (HND), Seoul's Incheon International Airport (ICN), and Washington Dulles International Airport (IAD) from six weekly to daily. Chicago and Mumbai will also receive more seats through aircraft upgauging, although SAS has not announced additional frequencies for these two routes. From Copenhagen Previous Service Summer 2027 Tokyo 6 weekly 7 weekly Seoul 6 weekly 7 weekly Washington DC 6 weekly 7 weekly Chicago A330-300, 266 seats A350-900, 300 seats Mumbai A330-300, 266 seats A350-900, 300 seats The A350 upgauges add 34 seats per departure, with capacity rising from 266 to 300 passengers. Mumbai Airport (BOM) is particularly noteworthy, having only launched in October this year, marking SAS's return to India after 17 years. Previously operated five times weekly with the A330, the route will enter its first full summer season with larger aircraft, demonstrating the airline's longer-term ambitions in the subcontinent. These changes precede SAS's largest-ever aircraft investment, announced in June of this year. The agreement covers up to 40 widebodies, including 18 firm Airbus A330-900 orders, two additional leased A330-900s, ten purchase rights, and up to ten additional Airbus A330-300s. The secondhand A330s will support near-term expansion, while new-generation aircraft will underpin fleet modernization. The investment has a stated list-price value exceeding $10 billion. SAS Strengthens Its European Network To Feed Copenhagen's Global Hub Credit: Ross Howey Photo | Shutterstock As if that wasn't enough, SAS is also strengthening its European and Scandinavian network to support Copenhagen's development as a major international connecting hub. Flights from Copenhagen to Stockholm Arlanda Airport (ARN) will increase from 15 to 18 daily departures, while Aarhus rises from four to five daily flights. Geneva, Barcelona and Venice will also gain significant additional capacity, improving connections between European destinations and SAS's expanding long-haul network. Route From CPH Previous service Summer 2027 Stockholm 15 daily Up to 18 daily Aarhus 4 daily 5 daily Geneva 13 weekly 19 weekly Barcelona 10 weekly 13 weekly Venice 8 weekly 11 weekly Ljubljana New route 2 weekly Menorca New route 1 weekly Beyond these confirmed increases, SAS also plans more departures from Copenhagen to Nice, Palma de Mallorca, Porto, Bilbao and Catania, although frequencies are not yet confirmed. Stockholm will gain additional flights to Luleå, Kiruna, Milan and Madrid, while Geneva and Keflavik services will operate throughout the summer. Oslo will also see increased frequencies to Manchester, Brussels and Rome. The expansion also introduces two new seasonal destinations from Copenhagen. Ljubljana Jože Pucnik Airport (LJU) launches June 25, operating twice-weekly until August 6 with a 122-seat Embraer E195. Menorca follows on June 30, with weekly flights until August 4 using a 180-seat Airbus A320neo. Menorca becomes SAS's third Balearic destination, while Ljubljana adds another European capital to its network. Together, the new additions reinforce Copenhagen's role as the airline's principal international hub.
