There is no nonstop path connecting Sky Harbor to Landvetter, which means every itinerary in business class from Phoenix to Gothenburg is built around a European or Scandinavian hub connection — and after dozens of trips on this exact corridor, I can say the routing you choose matters more than the fare class itself. SAS offers the most geographically logical option, typically routing through Copenhagen with a same-alliance hop up to Gothenburg, and their A350 business class product on the transatlantic leg delivers direct-aisle-access pods that make the roughly 10.5-hour crossing genuinely restful. Lufthansa's alternative via Frankfurt or Munich brings you into their evolving Allegris cabin on select aircraft, though not all PHX-originating itineraries will land you on the newest configuration, so it's worth checking the specific aircraft type before booking. KLM, routing through Amsterdam, remains the workhorse option with reliable World Business Class seating and some of the tightest connection banks into Scandinavia if you're time-sensitive.
My strong preference after years of testing these routings is the SAS-via-Copenhagen itinerary, largely because Copenhagen Airport's transfer process is refreshingly efficient compared to Frankfurt's sprawl or Amsterdam's Schiphol during peak summer congestion — you can often clear a connection in under 45 minutes if you're only carrying cabin luggage. One insider trick: on the KLM routing, request an early boarding group at PHX even in business class, since Terminal 4's international gates sometimes board via bus, and being first off the aircraft in Amsterdam meaningfully improves your odds of a smooth connection during the 1pm-3pm wave of incoming US flights.
Late spring through early autumn — May through September — offers the best combination of fare softness and daylight-heavy Scandinavian scenery, since airlines add capacity into Copenhagen and Amsterdam ahead of Nordic tourist season while corporate demand from Phoenix hasn't yet peaked. Because pricing on this three-airline, hub-dependent route fluctuates with connection combinations rather than a single carrier's calendar, setting up automated fare alerts is genuinely the smartest way to catch the periodic dips before they disappear.
