There's a peculiar satisfaction in routing yourself through a hub that actually makes sense, and after years of testing this itinerary, I've concluded that no combination of carriers gets you from the high desert of Nevada to the cobblestone squares of Nuremberg without at least one connection—there's no nonstop business class from Reno to Nuremberg, full stop. What exists instead is a choice among three solid American carriers, each routing you through a different European or domestic gateway: Delta typically connects via Atlanta or JFK before a transatlantic hop into Frankfurt or Munich, with a short regional finish into Nuremberg; American funnels traffic through Dallas or Charlotte into its Heathrow or Frankfurt gateways; and United leans on its Newark or Chicago hubs into Frankfurt or Munich, both close enough to Nuremberg that a rental car or a quick rail connection can save you the hassle of a third short-hop flight altogether.
On the long-haul segment, Delta's Airbus A330-900 or A350 flights out of JFK feature the Delta One suite with a closing door, genuinely one of the better US products for a red-eye into Germany, while United's polaris seats on 777s and 787s out of Newark offer solid recline and direct aisle access on most configurations. American's Flagship Suite, when you can snag it on the transatlantic leg, is another strong option, though it's worth confirming aircraft type before booking since American swaps equipment on European routes more than the others. My insider tip: once you land in Frankfurt or Munich, skip the connecting flight into Nuremberg if your schedule allows and take the train instead—it's often faster door-to-door once you factor in layover buffers, and it lets you enjoy a proper meal in the airport lounge rather than rushing to a puddle-jumper gate.
Winter and shoulder-season months—January through March, then October into November—consistently offer the softest fares on this corridor, partly because Nuremberg's Christmas markets draw leisure travelers earlier in the calendar while business travel dips elsewhere. Given how much these fares fluctuate with hub routing and seasonal demand, setting up automated fare alerts is the smartest way to catch a premium-cabin deal before it disappears.
