Trondheim rarely tops the wish list for premium cabin travelers, which is precisely why it rewards those willing to route through Europe's better hubs rather than search in vain for a nonstop that doesn't exist. There is no direct service between Oakland and Trondheim, so business class from Oakland to Trondheim requires a strategic transfer, and after dozens of bookings on this corridor, I've found that connecting through Amsterdam via KLM or Frankfurt/Munich via Lufthansa consistently outperforms routing through Scandinavia itself. KLM's World Business Class on its 787 and A330 fleet offers a comfortable, if not flagship, angled-flat product on the transatlantic leg, while Lufthansa's long-haul business class—particularly on 747-8 or A350 aircraft out of Frankfurt—gives you access to their excellent Senator Lounge before the short SAS or Lufthansa regional hop into Trondheim's compact Værnes airport.
SAS itself plays a crucial role on the final leg, and their A320neo business class, while a domestic-style product, is perfectly adequate for the one-to-two-hour intra-European segment. My preferred routing uses SAS for the Scandinavian connection whenever schedules allow, because their Oslo or Copenhagen hub minimizes layover friction and their ground crews handle tight connections into Trondheim with impressive efficiency—something you won't find written into any published transfer guide, but which frequent flyers on this route learn quickly. Arriving into Værnes, plan for its refreshingly small scale; bags appear fast, and taxis into central Trondheim take under thirty minutes, a welcome contrast to the sprawl of Frankfurt or Amsterdam you'll have just departed.
Summer remains the sweet spot for this itinerary, with May through September offering both favorable Nordic daylight and the best award and revenue fare availability, as airlines add capacity for Norway's tourist season. Because pricing on this three-airline routing fluctuates with both transatlantic and intra-European demand cycles, setting up automated fare alerts is the smartest way to catch the periodic dips that make premium travel to Trondheim genuinely attainable.
