Bari doesn't get the glamour treatment that Rome or Milan enjoy, which is precisely what makes routing business class from Miami to Bari such an interesting puzzle for the seasoned traveler. There's no nonstop option here — nor should you expect one, since this is a route defined entirely by its connections. Fact: the most efficient way to fly Miami to Bari in business class involves a transatlantic hop on Alitalia's successor ITA Airways (AZ), Lufthansa (LH), or Air France (AF), followed by a short regional leg into Bari's compact BRI airport. My preference, after flying this corridor numerous times, leans toward Lufthansa via Frankfurt — their long-haul 777 and A350 aircraft feature the newer Allegris business suites on select routes, though you'll want to check aircraft assignment carefully since older business seating still flies some Miami departures. Air France via Paris CDG offers their standard business product, a reliable if unspectacular flat-bed, with the advantage of Terminal 2E's Salon lounges for a comfortable layover.
If you're routing through Rome with ITA Airways, their A330 business class cabin — a holdover from the Alitalia era but well-maintained — connects smoothly to Bari on a short intra-Italy hop, often on the same ticket. This is my favorite itinerary of the three, mainly because ITA's Rome Fiumicino transfer process for international-to-domestic connections is refreshingly efficient if you clear passport control early and head straight to the dedicated shuttle gates. One insider tip: book the Rome-Bari segment as early in the day as possible, since afternoon flights on this domestic route see more weather-related delays coming off the Adriatic coast, which can jeopardize tight connections back to a transatlantic itinerary on your return.
Shoulder seasons — April, May, September, and October — are when this routing shines, both for pleasant Puglian weather and for softer business class demand out of Miami, since most premium leisure traffic to Italy peaks in summer. Given the multiple carrier options and connection points, fares on this itinerary fluctuate more than most transatlantic routes, so setting up fare alerts specifically for Miami-Bari business class itineraries will save you from overpaying during the narrow windows when award and revenue fares dip.
