Gothenburg rarely appears on the radar of American business travelers, which is precisely why the routing deserves attention: there is no nonstop option, and business class from Newark to Gothenburg requires a connection through one of three European hubs — Copenhagen, Frankfurt, or Amsterdam, served respectively by SAS, Lufthansa, and KLM. Having routed through all three more times than I can count, my preference tilts toward SAS via Copenhagen, since it's a genuine Scandinavian carrier flying Scandinavian metal on the short Gothenburg hop, and SAS's long-haul business product on the transatlantic sector — a proper flat-bed on their A330/A350 fleet — makes for a restful eight-and-a-half hour crossing before the quick 45-minute puddle jump north. Lufthansa passengers connecting via Frankfurt should note that aircraft assigned to this route vary, so the newer Allegris cabin isn't guaranteed, while KLM's World Business Class via Amsterdam offers dependable, understated Dutch efficiency with a strong Schiphol transfer experience.
The insider consideration most travelers overlook is the connection timing at Copenhagen: SAS's intra-Scandinavian network means CPH-GOT flights operate frequently, so booking a slightly earlier transatlantic arrival gives you flexibility to rebook onto an earlier regional flight at the gate if your connection is tight — something the app rarely surfaces but gate agents will accommodate. Amsterdam, by contrast, rewards early risers; Schiphol's passport control lines swell by mid-morning as European flights converge, so an early KLM connection avoids the worst of it. Frankfurt remains the wildcard — reliable but often congested, so pad extra time if you're transferring through Terminal 1's Star Alliance side.
Late spring through early autumn — May through September — is when Gothenburg deals cluster, largely because Scandinavian carriers time inventory releases around the region's short but glorious summer season, when Swedes themselves are traveling and premium demand from Sweden's substantial expat business community in the New York area peaks. Given how thin and volatile business class award and revenue space is on this niche routing, setting up fare alerts is the smartest move you can make before committing to a specific hub or carrier.
