Lufthansa does not build its own planes; instead, it maintains a diverse fleet primarily manufactured by the world's two largest aerospace giants: Airbus and Boeing. As the flag carrier of Germany, Lufthansa has a historically strong relationship with the European-based Airbus, operating a wide range of models including the A320 family for short-haul routes and the A350 and A380 for long-haul international flights. On the American side, Lufthansa is a major customer of Boeing, utilizing the Boeing 747-8 (the airline is one of the last major operators of the "Queen of the Skies") and the Boeing 787 Dreamliner. Additionally, for its regional subsidiaries like Lufthansa CityLine, the airline uses smaller jets built by Embraer (from Brazil) and Bombardier/Mitsubishi (the CRJ series). While Lufthansa doesn't manufacture the aircraft, it is world-renowned for its maintenance and engineering arm, Lufthansa Technik. This subsidiary is one of the leading providers of aircraft maintenance, repair, and overhaul (MRO) services globally, not only for Lufthansa's own fleet but for dozens of other airlines around the world, specializing in everything from engine repair to cabin outfitting.
