SAS has unveiled a sweeping summer 2027 schedule that puts Copenhagen front and centre — and the biggest winners are travellers heading to the US. From June, Copenhagen-Atlanta jumps from five flights a week to a daily service, a 40% bump, while Seattle rises from four to five weekly departures. Both are Delta hubs, and both frequencies are restorations of routes SAS has run before. Atlanta launched in June 2024, just before the airline formally joined SkyTeam, and SAS already flies nonstop to three other Delta hubs: Boston, Los Angeles and New York-JFK.

The Delta tie-up keeps deepening. A codeshare signed in September 2024 now covers around 150 North American destinations and roughly 50 in Northern Europe, with reciprocal loyalty perks added in April 2025. The relationship could tighten further still: Air France-KLM hopes to close its acquisition of a 60.5% controlling stake in SAS in the first quarter of 2027, pending EU approval — a deal that could eventually fold SAS into the Delta–Air France–KLM–Virgin Atlantic transatlantic joint venture.

It's not just North America. Copenhagen-Tokyo Haneda, Seoul Incheon and Washington Dulles all go daily (up from six weekly), while Chicago and Mumbai keep their schedules but swap the A330-300 for the larger A350-900, adding 34 seats per flight. The Mumbai route is one to watch — it only launched in October, marking SAS's return to India after 17 years, and 2027 will be its first full summer season.

On the ground in Europe, SAS is thickening its Copenhagen feeder network to make connections smoother. Stockholm Arlanda climbs to up to 18 daily departures, Aarhus to five, and Geneva, Barcelona and Venice all gain meaningful capacity. Two brand-new seasonal routes appear too: Ljubljana from June 25 (twice weekly on an E195 until August 6) and Menorca from June 30 (weekly on an A320neo until August 4) — the airline's third Balearic island. More frequency increases to Nice, Palma, Porto, Bilbao and Catania are flagged but not yet confirmed, and Stockholm, Oslo and Geneva also pick up extra summer services.

For holidaymakers, the practical upshot is simple: from mid-2027 it'll be easier to fly from Scandinavia to North America and Asia without awkward layovers, and one-stop access from smaller European cities via Copenhagen gets better too. If you've been eyeing Slovenia's capital or a quieter Balearic beach, summer 2027 is your window — both new routes are short seasonal runs ending in early August.
