Sicily's Catania has never had a prayer of a nonstop from New England, so every itinerary in business class from Providence to Catania runs through a European or East Coast hub, and after years of routing myself through this corner of the Mediterranean, I've settled on a clear hierarchy of preferences. The honest fact worth knowing upfront: there is no direct PVD–CTA service on any carrier, so travelers connect via Delta's JFK or Boston gateways into Rome or Amsterdam-style partner hubs, via Alitalia's successor ITA Airways through Rome Fiumicino, or via Lufthansa through Frankfurt or Munich — all feeding a short intra-European hop down to Catania's compact single-terminal airport. Total journey time hovers around ten hours of air time, but realistic door-to-door travel with connections often stretches past thirteen.
My preferred routing threads through Frankfurt on Lufthansa, where their long-haul business class seats (increasingly the newer Allegris cabin on select aircraft, though still legacy business on many transatlantic frames) offer direct aisle access and a genuinely restful lie-flat product before a manageable connection down to Sicily. ITA Airways through Rome is the romantic's choice — their A330 and A350 business cabins have improved dramatically since the Alitalia days, with proper Italian dining service that sets the tone for the trip before the final CTA hop. Delta, meanwhile, is strongest if you can position through JFK, pairing their Delta One suites (on A330-900 or A350 equipment on the transatlantic leg) with a SkyTeam partner connection into Rome or Milan. My insider tip: build in a three-hour-plus connection in Rome specifically to clear passport control calmly, since Fiumicino's Schengen transfer process can eat sixty minutes even off a business class arrival.
April, May, September, and October reward patient shoppers with the best combination of mild Sicilian weather and softer transatlantic business fares, well ahead of summer's peak demand. Given how much these connecting itineraries fluctuate week to week, I'd strongly recommend setting up automated fare alerts rather than checking manually — this route rewards vigilance more than almost any other Italy gateway I track.
