On the airline side, American routes travelers through Charlotte or Dallas and onward via a European gateway, with its Flagship Business product delivering a lie-flat suite in 1-2-1 configuration, Casper bedding, and Flagship Lounge access domestically. Delta's competing option runs through Atlanta or Minneapolis, and its Delta One Suite is the standout for privacy-focused flyers — a closing door, generous storage, and a Tumi amenity kit that's genuinely useful rather than throwaway. Air France connects via Paris CDG, and its Business cabin brings real French cuisine and stemware service along with La Première lounge access for those with elite status or premium tickets. Lufthansa routes through Frankfurt with its newer Allegris Business suites, a 1-2-1 lie-flat layout with more privacy panels than Lufthansa's older cabins, plus the airline's characteristically efficient ground service. All four are strong choices for RDU to Chania business class, and the right pick usually comes down to which US gateway (DFW, CLT, ATL, MSP) is most convenient and which European hub you don't mind connecting through.
