For Charlotte to Bari business class, four carriers offer strong connecting options. American Airlines routes through its hubs with the Flagship Business lie-flat suite in a 1-2-1 layout, Casper bedding, and Flagship Lounge access if your connection runs through a hub city with one. Delta Air Lines counters with the Delta One Suite — a closing door, genuine privacy, and a Tumi amenity kit, connecting through JFK or Atlanta before linking to a European partner into Bari. British Airways flies its Club Suite, also with a closing door and 1-2-1 configuration, dressed in White Company bedding, typically routing through London before a short intra-European hop down to Puglia. Lufthansa's Allegris Business, rolled out on its A350 fleet, gives you a lie-flat suite with the kind of methodical service Lufthansa is known for, connecting through Frankfurt or Munich. Each airline's transatlantic leg is the long haul that matters most for sleep — the European connector down to Bari is usually under three hours, so don't overthink that segment when comparing fares.
