What is the fastest way to fly business class from O'Hare to Nantes Atlantique? The answer depends on which European hub you connect through.

Lufthansa via Frankfurt and British Airways via London Heathrow are competitive alternatives, each offering well-regarded transatlantic business class cabins on widebody aircraft for the ORD-CDG or ORD-LHR long-haul leg.
