Trondheim is not a city most Norfolk travelers stumble into by accident, and that's precisely why the routing deserves careful thought. There is no nonstop option here — business class from Norfolk to Trondheim always involves a connection through a major European hub, and the total journey time, including the transfer, typically runs well beyond the advertised 8.5-hour flight time once you factor in the connection. My preferred routing is SAS via Copenhagen, since their Airbus A330 and A350 business class cabins offer lie-flat seats with direct aisle access and Copenhagen's compact layout makes for painless transfers even on tight connections. Lufthansa via Frankfurt or Munich is a strong alternative, particularly if you can snag one of their newer Allegris-configured aircraft, while KLM's routing through Amsterdam brings World Business Class on the 787 or A330, with Schiphol's efficient transfer security a genuine time-saver on the return leg.
Having routed through all three hubs repeatedly, my strong recommendation is Copenhagen when schedules allow — SAS treats this Scandinavian corridor as something of a home turf specialty, and their onward narrowbody or regional jet service into Trondheim tends to run smoothly even in shoulder season weather. One insider tip worth noting: Trondheim's Værnes Airport is small enough that even a 45-minute connection from an SAS domestic flight feels comfortable, so don't over-buffer your itinerary the way you might for a larger European gateway — doing so just adds hours you don't need. Norwegian summer, from May through September, is both the most scenic time to arrive (endless daylight over the fjords is worth the window seat) and consistently the best window for business class value on this corridor, as leisure demand into Scandinavia peaks but competitive capacity among SAS, Lufthansa, and KLM keeps fares more reasonable than winter's business-heavy pricing.
Because this is a thin, connection-dependent route with three competing carriers and no dominant nonstop, fares can swing quickly based on hub competition and seasonal demand — which makes setting up automated fare alerts for this specific city pair one of the smartest moves a Trondheim-bound traveler can make.
