Bari's Puglia coastline doesn't get the direct-flight glamour of Rome or Milan, which is precisely why the routing puzzle matters so much here: there is no such thing as nonstop business class from Buffalo to Bari, and anyone telling you otherwise is guessing. What you're actually booking is a two-stop itinerary via a major European hub, typically funneling through JFK or Detroit before a transatlantic leg on Delta or a Delta/Air France-KLM partner, or alternatively routing through Frankfurt or Munich on Lufthansa, then down to Bari on a short intra-European hop, often operated by ITA Airways (formerly Alitalia) given Italy's domestic network. Total journey time runs close to 10 hours in the air alone, before you factor in connection buffers.
Having threaded this itinerary more times than I'd like to admit, my strong preference is the Lufthansa routing through Munich or Frankfurt over Delta's JFK gateway — Lufthansa's long-haul business class seats (increasingly the new Allegris cabin on select aircraft, though older 747-8 and A350 configurations still fly plenty of Atlantic routes) offer more consistent lie-flat comfort than squeezing through JFK's T4 during peak evening congestion. If your itinerary lands you on ITA for the final Bari sector, don't expect business-class theatrics on that short hop — it's essentially a recliner seat with a coffee and cornetto, and the real luxury happens on the long-haul segment before it. One insider trick: build in a deliberate 3-4 hour layover in Frankfurt or Munich rather than a tight connection, since Puglia-bound ITA flights are notoriously light on schedule padding and misconnects here mean losing a full day, not just hours.
April, May, September, and October reward patient travelers, both for Puglia's shoulder-season weather and for softer transatlantic business fares before summer's Amalfi-adjacent crowds hit southern Italy. Given the complexity of pairing carriers and the fare volatility across three airlines' revenue systems, setting up automated fare alerts for this specific city pair is genuinely the smartest way to catch the rare moments when pricing dips into reasonable territory.
