Rhodes has always struck me as one of those Aegean prizes that rewards patience in the booking process, and after routing through this corridor more times than I can count, I can say definitively that there is no nonstop option for business class from Cincinnati to Rhodes — every itinerary funnels through a major European gateway, with Frankfurt via Lufthansa, London Heathrow via British Airways, or Athens via Aegean Airlines representing the three viable paths. My preference leans toward Lufthansa's Frankfurt connection, since CVG's transatlantic lift pairs naturally with Lufthansa's growing Allegris cabin rollout on select long-haul aircraft, though on this route you're just as likely to encounter the reliable 747-8 or A340 business product depending on aircraft assignment — always worth checking your specific equipment at booking. British Airways routes through Heathrow with its Club Suite on many long-haul aircraft, a fully enclosed suite with direct aisle access that makes the overnight transatlantic leg genuinely restful before a same-day connection down to Rhodes on a narrowbody.
The real insider move here is the Athens connection via Aegean, Greece's flag carrier, which — while not offering a premium widebody product on the short RHO hop — provides the most seamless final approach into Rhodes International, landing you close to the Old Town and avoiding the fatigue of a second long-haul segment. I've found that building in a two-to-three hour buffer in Athens pays dividends, since Aegean's short-haul Rhodes flights depart from a different pier than most arriving international connections, and misconnects during peak Greek island season are common. Shoulder season — April, May, September, and October — consistently delivers the best combination of manageable fares and pleasant Rhodes weather, avoiding both the July-August crowds and the shoulder-season storms that can disrupt Athens-Rhodes short-hop schedules.
Given how few seats each of these carriers releases in business class on the Rhodes-bound legs, and how quickly award and discounted fares vanish during shoulder months, I'd strongly recommend setting up fare tracking alerts well in advance rather than checking manually — this route rewards those who move fast when a window opens.
