Nuremberg's absence of transpacific-to-Europe nonstops means every itinerary from Hawaii is an exercise in strategic connections, and after years of routing through West Coast gateways I can say definitively: there is no direct business class from Honolulu to Nuremberg, so the routing you choose matters as much as the seat you sit in. American, Delta, and United all serve this corridor via major hubs, with United's option through San Francisco or Chicago into Frankfurt or Munich (followed by a short rail or connecting flight to Nuremberg) typically offering the smoothest experience, particularly aboard United's Polaris business class with its lie-flat seats and direct aisle access on the 777 and 787 fleet. Delta routes through its Atlantic joint venture partners, often connecting through Los Angeles or Seattle before a transatlantic hop to Frankfurt or Amsterdam, while American leans on its oneworld partnership, typically funneling passengers through Dallas or Los Angeles into London or Frankfurt before the final leg into Bavaria.
Having flown this multi-segment journey more times than I can count, my advice is to treat the Honolulu-to-mainland segment as the wildcard: book the widebody redeye out of HNL whenever possible, since narrow-body substitutions on this first leg can quietly downgrade your seat comfort before you've even crossed the Pacific. An insider tip few mention: Munich, not Frankfurt, is often the smarter connection point into Nuremberg, since the regional rail link from Munich's airport is faster and less congested than the equivalent Frankfurt transfer, saving you nearly an hour of ground time after a long-haul flight.
January through March and again in October and November are your sweet spots for award and paid business class value, as European leisure demand dips and Bavarian business travel (outside Nuremberg's toy fair season) remains steady rather than surging. Given how frequently pricing shifts across three carriers and multiple hub combinations, setting up fare alerts for this specific Honolulu–Nuremberg pairing is the only reliable way to catch the rare moments when premium cabin pricing dips into genuinely attractive territory.
