Omaha's business travelers heading to Baden-Württemberg's industrial heartland face a fundamental truth: there is no nonstop option here, and business class from Omaha to Stuttgart always routes through a major connecting hub, typically Atlanta, Chicago, or Newark/Washington Dulles, before crossing the Atlantic. Delta's most sensible routing sends passengers through Atlanta on a Delta One product—often the Delta One Suite with sliding door on widebody aircraft—before a connection into Stuttgart via Amsterdam or another European gateway, since none of these three US carriers fly direct into STR. American routes through Chicago O'Hare, connecting onto oneworld partner metal (frequently British Airways or Finnair) for the transatlantic leg, while United typically funnels traffic through Newark or Washington Dulles onto its Polaris business class, a genuinely comfortable reverse-herringbone seat with direct aisle access, before a European connection completes the journey into Stuttgart's compact but efficient airport.
Having routed through all three hubs repeatedly, my strong preference is Newark-United-Polaris when schedules align, simply because Newark's connection times to Star Alliance partners into Stuttgart tend to be more forgiving than Atlanta's tight banked connections during winter irregular operations. One insider tip worth noting: Stuttgart Airport's arrivals process is refreshingly fast for a European hub—if you clear immigration within the first wave off your inbound flight, you can be in a taxi within twenty minutes, so don't dawdle at baggage claim if you booked business class with priority tags. Seasonally, this Midwest-to-Germany corridor sees its softest business class fares in deep winter and shoulder months—January, February, March, October, and November—when Stuttgart's automotive-industry business travel dips outside major trade show windows.
Because pricing on this indirect, multi-carrier routing fluctuates heavily with hub congestion and partner award space, I'd strongly recommend setting up automated fare tracking for Omaha–Stuttgart business class rather than checking manually, since the best fares on this route often appear briefly and without warning.
