Several major airlines around the world are known for operating some of the most diverse fleets that include both Boeing and Airbus aircraft. These airlines typically operate a mix of narrow-body and wide-body aircraft, as well as multiple sub-types within each family, giving them flexibility for both domestic and international routes.
Delta Air Lines (USA) is widely recognized for having one of the most diverse fleets in the world. As of now, Delta operates nearly 1,000 aircraft, with a mix of Airbus and Boeing models. From Boeing, it includes the 717, 737, 757, 767 series, and from Airbus, the A220, A319, A320, A321, A330, and A350. It also has various regional jets like the CRJ and Embraer aircraft. This combination allows Delta to serve a wide range of short- and long-haul markets efficiently.
Lufthansa (Germany) also maintains a highly diverse fleet, operating both Airbus and Boeing aircraft. Its fleet includes the Airbus A319, A320/neo, A321/neo, A330, A340, A350, and A380, alongside Boeing 747 and 787 models. Lufthansa also incorporates regional jets such as the CRJ and Embraer series, making its fleet versatile for all types of routes across Europe and globally.
United Airlines (USA) operates one of the largest and most varied fleets, featuring more than 800 aircraft. It has a strong presence of Boeing aircraft, including the 737 (in several sub-types), 757, 767, 777, and all three variants of the 787 Dreamliner.

American Airlines, another major U.S. carrier, also uses both Boeing and Airbus jets. The airline operates the Boeing 737, 777, and 787, along with Airbus A319 and A321 (including A321neo). Although it leans more toward narrow-body aircraft for domestic flights, its Boeing wide-bodies are used for international routes, contributing to a balanced mix.
Turkish Airlines has a strong reputation for fleet diversity as well, operating both Boeing and Airbus aircraft across various capacities. It uses Airbus A319, A320, A321, A330, and A340, along with Boeing 737, 777, and 787 models.

In Asia, the HNA Aviation Group of China (which includes several airlines) also operates a wide range of aircraft from both Boeing and Airbus. Its fleet includes Boeing 737s, 747s, and 787s, as well as Airbus A319s, A320s, A321s, and A330s. The group uses this fleet to serve both domestic routes within China and international destinations.
Lastly, Emirates from the UAE, while primarily operating wide-body aircraft, has a mixed Boeing-Airbus fleet. It is best known for its large fleets of Airbus A380s and Boeing 777s, and is also introducing the Airbus A350. Emirates’ use of only large aircraft is unique, but the mix of Boeing and Airbus models still adds to its fleet diversity.
