Gothenburg rarely gets the transatlantic attention Stockholm does, which is precisely why frequent flyers in the know quietly appreciate the routing options available. There is no nonstop from Mitchell International, so business class from Milwaukee to Gothenburg means choosing your connection wisely — and after dozens of trips through this corridor, I can tell you the hub matters more than the carrier's home country. SAS routes efficiently through Copenhagen with its A350 and A321LR business class, offering a genuinely Scandinavian experience before the short hop north to Landvetter Airport. Lufthansa's Frankfurt or Munich connections give access to their evolving Allegris cabin on select long-haul aircraft, though older 747-8 and A340 business configurations still appear on this corridor, so it's worth checking your specific aircraft before booking. KLM, meanwhile, funnels traffic through Amsterdam's Schiphol, pairing efficient connections with their reliable 787 and A330 business class product.
My strongest recommendation, built from years of testing all three options, is routing through Copenhagen on SAS whenever schedules allow — the connection time is short, immigration into Sweden becomes a non-issue since you're already in the Nordic zone, and SAS's Copenhagen hub avoids the security bottlenecks that can plague Frankfurt during peak summer travel. If you're transiting Amsterdam or Frankfurt instead, build in at least 90 minutes, as both airports see significant midday congestion from May through September, which happens to be the sweet spot for this route's best fares. Scandinavian carriers also tend to release stronger business class award space in shoulder months like May and September, before Nordic tourism peaks and after it recedes.
One insider trick: Gothenburg-bound business travelers often overlook that flying into Copenhagen and taking the train onward via Öresund can occasionally beat the connecting flight's total travel time, especially when SAS schedules a longer layover. Given how much these fares fluctuate by connection and season, setting up dedicated alerts for this specific city pair remains the smartest way to catch premium-cabin value before it disappears.
