There's a particular satisfaction in routing yourself through a proper European hub rather than fighting the crowds at JFK, and that's precisely the calculus behind smart business class from Providence to Malmo itineraries. Since PVD offers no direct widebody service, the honest answer to how one reaches southern Sweden in comfort is via connections through Copenhagen, Frankfurt, or Amsterdam — with Copenhagen (just a short train or transfer away from Malmo Airport's limited schedule) being the most elegant solution given SAS's home-hub advantages. I've routed this journey a dozen times, typically flying PVD-JFK or PVD-EWR on a domestic partner before transatlantic connections, and the SAS option via Copenhagen consistently wins for total journey comfort: their A330/A350 business class delivers fully flat seats with direct aisle access, and Copenhagen Airport's transfer process to reach Malmo (a 25-minute train ride across the Öresund Bridge) is refreshingly efficient compared to fighting Stockholm traffic.
Lufthansa via Frankfurt is my second recommendation, particularly if your positioning flight naturally routes through Newark or Boston — their long-haul business class cabins, especially on the 747-8 and A350, remain a reliable choice, though Allegris-equipped routes are still being rolled out gradually and haven't yet reached this corridor consistently. KLM through Amsterdam rounds out the trio, and Schiphol's efficient transfer infrastructure makes the connection to Copenhagen or direct Amsterdam-Malmo hops relatively painless during summer schedules.
My insider tip: book the SAS codeshare leg separately if possible, since standalone Copenhagen-Malmo positioning fares (or the train) often price out cheaper than forcing a single through-ticket, and this flexibility lets you optimize your transatlantic business class seat selection independently. May through September remains the sweet spot for this route, both for Scandinavian weather and for award availability opening up as summer leisure demand shapes airline inventory management. Given how fares fluctuate across three carriers and multiple hub combinations, setting up dedicated fare alerts for this specific city pair will save considerably more legwork than manually checking each airline's site.
