Airbus launched the A320neo in December 2010. The name means new engine option. Fuel prices were climbing, and new rivals were eyeing the single-aisle market. Rather than design a brand new jet, Airbus kept the proven A320 body and fitted two modern engines: the CFM LEAP-1A and the Pratt & Whitney PW1100G geared turbofan. Large curved wingtips, called sharklets, were added to cut drag. Everything else stayed the same.
The first A320neo flew on September 25, 2014. Lufthansa began flying passengers in January 2016. The new engines burn roughly 15 to 20 percent less fuel per seat than the original A320. Airlines around the world rushed to order, and the whole family became the fastest-selling airliner program in history. Low-cost giants such as IndiGo, easyJet, Wizz Air and Frontier planned their entire growth around it.
Network airlines use the neo to replace older A320s one for one. Together with its sister models, it helped the A320 family pass the Boeing 737 as the best-selling airliner line ever. Today the A320neo is a common sight at airports on every continent. It has become the standard short- and medium-haul workhorse of the 2020s. Assembly lines in Toulouse, Hamburg, Tianjin and Mobile all build it.
