The Airbus A321XLR is a next-generation narrowbody aircraft produced by Airbus that is set to redefine what a narrowbody jet is and what it can do. The plane comes with an advertised range of up to 4,700 nautical miles (8,700 km). The XLR gives airlines widebody-style reach on long-and-thin routes that cannot support larger twin-engine aircraft. Early operators are already proving the concept, as Iberia has deployed the type on North Atlantic sectors served from Madrid, including flights to Boston and a forthcoming Madrid to San Juan service that will become one of the XLR’s longest flights.
