Palm Beach International doesn't hand you a nonstop to Arlanda, and after years of routing through this corridor, I've made peace with the connection as part of the ritual rather than a hindrance. There is no direct service on this city pair, so business class from West Palm Beach to Stockholm requires a one-stop itinerary via a major East Coast or transatlantic gateway, typically New York-JFK, Newark, or a European hub depending on which of the three American carriers—American, Delta, or United—you're booking through. American routes you through JFK onto its transatlantic partners or its own metal into London or occasionally a codeshare arrangement, while Delta's strength lies in its JFK and Boston connections onto Air France-KLM or its own Delta One product on the westbound legs of the journey. United, meanwhile, leans on its Newark hub, feeding into Lufthansa or its own aircraft toward Scandinavia. Total journey time including the connection typically runs well past the 9.5-hour flying time of the long-haul segment alone, so building in a two-hour buffer at your connecting hub is essential, particularly during winter when Northeast weather delays cascade through JFK and Newark with regularity.
What separates a smooth PBI-to-ARN routing from a stressful one is the layover architecture, not the long-haul cabin itself. I always tell friends flying this route to prioritize the airline whose connecting hub has the shorter walk between international arrivals and departures—Newark's United terminal setup tends to be more forgiving than JFK's Terminal 8 during peak transatlantic banks in the early evening. If your itinerary lands you on a Delta One suite with the sliding door on the transatlantic leg, that privacy is worth angling for in seat selection at booking, since not every aircraft in the fleet carries the newest configuration. Arlanda itself rewards early risers—arriving mid-morning off an overnight flight lets you clear passport control before the crush of intra-European arrivals hits.
Late spring through early fall—May through September—consistently offers the most favorable business class availability and value on this corridor, as Scandinavian demand peaks and carriers add capacity to meet it, which paradoxically loosens premium inventory rather than tightening it. Given how much these connecting itineraries fluctuate week to week, setting up fare alerts on this specific PBI–ARN pairing will save you far more than guesswork ever could.
