Corfu's turquoise coastline rewards patience, and nowhere is that truer than in the routing puzzle of getting there properly seated. There is no nonstop option, so business class from Chicago to Corfu always involves a connection, typically through Frankfurt, London Heathrow, or Athens, depending on which of the three carriers serving this corridor you choose. Lufthansa, British Airways, and Aegean Airlines each offer a distinct flavor of this journey, and having routed through all three hubs repeatedly, I can say the Frankfurt connection via Lufthansa tends to be the smoothest for protecting a tight onward Aegean or Lufthansa regional flight into CFU, especially in the summer high season when Corfu's small airport gets congested with charter traffic.
The long-haul segment is where the real decision lies. Lufthansa's transatlantic leg from ORD to FRA increasingly features the new Allegris business class on select aircraft, with its private suite doors and adjustable panels, though older 747-8 configurations still fly this route seasonally, so it's worth checking your aircraft type at booking. British Airways routes through Heathrow with its Club Suite product on the ORD-LHR sector, giving every passenger direct aisle access and a proper door, a meaningful upgrade over BA's older Club World cabins that some travelers still remember unfavorably. From either European hub, Aegean Airlines handles the final hop to Corfu, and while their intra-European business class is a simpler recliner seat with blocked middle seats, the segment is short enough that comfort matters less than connection timing.
My insider tip: build in at least a 90-minute buffer in Athens or Frankfurt during peak Greek travel weekends, as Aegean's Corfu departures shift gates frequently and immigration lines at ATH can bottleneck unexpectedly. April, May, September, and October remain the sweet spot for both fares and weather, avoiding August's crowds while still enjoying warm Ionian waters. Given how these connecting itineraries fluctuate across three separate carriers, setting up fare alerts for this specific routing is the smartest way to catch the inevitable dips before they disappear.
