After two decades of routing clients through half of Scandinavia, I can tell you plainly: there is no nonstop path here, and business class from Pittsburgh to Malmo always means a connection through a major European gateway, typically Frankfurt, Amsterdam, or Copenhagen. Given that Malmo's MMX airport is modest, the real strategic decision happens upstream — and Copenhagen via SAS is the smartest routing for most travelers, since Kastrup sits a mere 30-minute train ride (or scenic drive across the Öresund Bridge) from Malmo's city center, effectively making CPH the true gateway to this corner of southern Sweden. SAS operates its A350 with a proper business class flat-bed product on the transatlantic legs it flies from the US, though PIT itself has no direct SAS service, so most itineraries funnel through New York, Chicago, or Washington first.
Lufthansa via Frankfurt offers another dependable option, particularly appealing now that its long-haul fleet is gradually rolling out the new Allegris business seats with sliding doors on select aircraft — worth requesting specifically when booking, since older 747-8 and A340 configurations still lack this privacy feature. KLM's route through Amsterdam is my personal favorite for connection ease, thanks to Schiphol's single-terminal design, which makes the transfer to a short intra-European hop toward Copenhagen or Malmo far less stressful than fighting through Frankfurt's sprawling terminals during peak summer congestion. My insider tip: fly into Copenhagen rather than connecting onward to Malmo by air entirely — skipping that final short-hop flight and taking the train instead often saves both money and aggravation, and it's a trick most US travel agents never mention.
Late spring through early autumn — May through September — brings not only the best fares but also Scandinavia's long daylight hours, making arrival into Copenhagen or Malmo far more pleasant than the dark winter months. Given how fare structures shift constantly across these three carriers and their partner networks, I'd strongly recommend setting up automated price tracking for this specific corridor rather than checking manually, since business class award space and fare sales on this Pittsburgh–Scandinavia routing tend to appear and vanish within days.
