There's no shortcut from Indianapolis to the Norwegian fjords, and that's precisely what makes the routing strategy so interesting. There is no nonstop option here — business class from Indianapolis to Bergen always routes through a major European hub, and the choice of connection shapes the entire experience. SAS runs its Airbus A350 and A321LR business cabins through Copenhagen, with lie-flat seats and a genuinely Scandinavian sense of calm design, then hands off to a short SAS regional hop into Bergen. Lufthansa's preferred gateway is Frankfurt or Munich, where its long-haul business class — increasingly featuring the new Allegris seats on select aircraft — connects onward via Lufthansa or partner metal, though most Frankfurt-Bergen segments run as premium economy or economy-configured narrowbodies, so the real luxury is banked on the transatlantic leg. KLM funnels travelers through Amsterdam Schiphol, pairing its A330/787 business class with a well-timed KLM Cityhopper connection to Bergen, and Schiphol remains, in my experience, the easiest of the three hubs for a tight or leisurely connection thanks to its single-terminal layout.
Having flown all three routings multiple times, my strong preference is Amsterdam: Schiphol's efficiency shaves real stress off a long connecting day, and KLM's lounge access via Skyteam partners is dependable. Copenhagen is a close second, especially if you want to experience SAS's newer long-haul product, though winter connections into Bergen can be weather-sensitive — Bergen's airport (Flesland) sees frequent rain and occasional fog delays, so I always book a connection with at least 90 minutes of buffer, more in winter. An insider tip few mention: SAS's Copenhagen-Bergen domestic hop often uses smaller aircraft with no dedicated business cabin, so your seat may simply be an economy seat with a blocked middle — worth knowing before you set expectations for that last leg.
Seasonally, May through September brings both better weather for Bergen's dramatic scenery and more competitive business class fares, as Norwegian tourism demand peaks and airlines add capacity. Given the volatility in transatlantic pricing on this three-airline route, I'd recommend setting up fare alerts rather than checking manually — automated tracking tends to catch the shoulder-season dips before they disappear.
