Bologna rarely gets the attention Milan or Rome commands, which is precisely why savvy travelers from the Gateway City have quietly made it a favorite Emilia-Romagna entry point. There's no nonstop option here, so business class from St. Louis to Bologna always means a connection, and the routing you choose shapes the entire experience. Delta's most sensible path runs through Atlanta or JFK before crossing to Amsterdam or Paris on a widebody, while Lufthansa funnels STL travelers through Frankfurt or Munich, and Alitalia's successor ITA (still flying under the AZ code you'll see in booking systems) offers a Rome connection that appeals to those wanting a single-carrier itinerary into Bologna's compact airport.
My preference on this routing leans toward Lufthansa, particularly if you can secure one of their retrofitted Allegris business suites now rolling out on select 787 and A350 aircraft — sliding doors and genuine bed-flat comfort make the long transatlantic leg from St. Louis genuinely restful before the short European hop down to Bologna. Delta's Atlanta connection works well operationally since STL-ATL is a reliable, frequent hop, and their transatlantic widebodies (767s and A330s with Delta One suites) are consistently comfortable, though you'll want at least 90 minutes in Atlanta given occasional TSA lines. An insider tip few mention: flying into Bologna rather than Rome or Milan saves you the chaos of Fiumicino or Malpensa transfers entirely, since BLQ is a small, walkable airport where business class passengers often clear immigration and collect bags within twenty minutes.
April, May, September, and October remain the sweet spot for this itinerary — shoulder season in Emilia-Romagna means better weather for exploring the Bologna countryside and noticeably better award and premium cash availability than peak summer. Because fare and award space on this multi-carrier routing fluctuates unpredictably week to week, setting up automated fare alerts is the smartest way to catch a business class opening before it disappears.
