Gothenburg rarely gets the glamour treatment in transatlantic route planning, which is precisely why the smart money routes through Frankfurt, Amsterdam, or Copenhagen rather than waiting for a nonstop that doesn't exist. There is no direct service between Houston and Gothenburg, so business class from Houston to Gothenburg means a connection, and the choice of hub matters enormously to how the journey feels. Lufthansa via Frankfurt puts you in line for the airline's new Allegris business suites on select 787 and A350 rotations, though older 747-8 and A340 configurations still fly plenty of IAH-FRA sectors, so it's worth checking aircraft type before booking. KLM through Amsterdam offers a reliably efficient Schiphol connection with a shorter final hop to Gothenburg on their regional fleet, while SAS via Copenhagen is the most culturally logical routing, landing you close to Scandinavia before a quick onward hop that barely disrupts your body clock.
Having flown all three combinations repeatedly, I'd steer discerning travelers toward the Copenhagen connection when schedules align. SAS's Copenhagen hub is compact and connection times are forgiving even in winter irregular operations, and there's a psychological benefit to landing in Scandinavia early rather than fighting through a sprawling Frankfurt terminal on minimal sleep after a ten-hour overnight from Houston. My insider tip: request the window seat on the left side (K) on Lufthansa's 747-8 upper deck business cabin if you get assigned that aircraft — it's quieter and the upper deck boards separately, cutting your onboard wait considerably.
Late spring through early autumn — May through September — brings the best combination of fare availability and Nordic weather, since Gothenburg's archipelago and coastal charm reward daylight arrivals rather than the gray, short days of a Scandinavian winter. Award space on SAS and Lufthansa tightens considerably once European vacation season peaks in July, so flexibility on connection city can be the difference between a QSuite-adjacent business seat and a middle-of-the-cabin scramble. Given how fare and award availability shifts week to week on this three-airline, one-connection route, setting up automated price tracking is the easiest way to catch the openings before they vanish.
