Trondheim rarely appears on the American business traveler's radar, which is precisely why the routing deserves attention: there is no nonstop option, so business class from New Orleans to Trondheim means threading through Amsterdam, Frankfurt, Munich, or Copenhagen before the final short hop north. The total journey clocks in well beyond the nominal ~8.5 hour flight time once connections are factored in, but the itinerary rewards patience with three genuinely strong long-haul products to choose from — KLM's World Business Class on the transatlantic legs out of Amsterdam, Lufthansa's evolving Allegris business suites (where equipped) on Frankfurt or Munich routings, and SAS Business on their Scandinavian-metal aircraft, which often proves the most seamless choice given SAS's natural feeder network into TRD via Copenhagen or Oslo.
Having routed through all three hubs repeatedly, I'd steer discerning travelers toward the SAS connection through Copenhagen whenever schedules align — the transfer process at CPH is refreshingly calm compared to Frankfurt's sprawl, and SAS's own short-hop business cabins up to Trondheim, while modest, keep the journey coherent under one alliance. My insider tip: build in a Copenhagen or Amsterdam layover of at least three hours during the May-through-September window, since Trondheim's connecting flights from these hubs thin out considerably in shoulder season, and misconnections here mean waiting until the next day's departure rather than a quick rebooking.
Summer is unambiguously the sweet spot for this routing — not just for fares, but for Trondheim itself, where the midnight sun extends daylight deep into the evening and the fjord-side arrival becomes genuinely spectacular rather than a gray afterthought. Award space in KLM and Lufthansa business cabins from the US Gulf Coast tends to loosen up in late spring as European carriers rebalance capacity for the tourist season, though SAS's smaller aircraft on the final leg keep seats scarce regardless. Given how these fares shift week to week across three separate carriers and four possible hub cities, setting up fare alerts for this specific New Orleans–Trondheim pairing is the smartest move you can make before booking.
