Only a handful of airlines remain committed to flying quad-engined passenger jets, a testament to their enduring popularity among certain routes and passengers. According to data from various sources, including airline fleet pages and aviation databases, there are now fewer than 12 airlines operating four-engine aircraft for commercial passenger service. This decline is largely driven by the increasing efficiency of newer single-engine and twin-engine designs.
The exclusion of charter airlines and government-operated quad-jets from this list highlights the changing nature of the industry. Cargo airlines, which once operated most of the world's remaining commercial quadjets, have shifted their focus to more fuel-efficient aircraft. This shift has significant implications for the environment and the airline industry as a whole.
Rossiya Airlines, which reactivated several Boeing 747-400s for domestic routes due to sanctions, is not included in this list. Similarly, Iranian airlines like Mahan Air may have lost some of their A340s in the 2026 US/Israeli air campaign over Iran. Cuba's Cubana de Aviación, with its unique Il-96 quad-engined passenger jet, is also omitted from this tally.
All Nippon Airways stands out among Japanese carriers for its late and limited order for the Airbus A380. With only three superjumbos in service, ANA's fleet is remarkably young, averaging just 7.1 years old. The airline's decision to prioritize the A380 reflects its commitment to offering unique passenger experiences.
ANA's A380s are renowned for their striking liveries, which have become a hallmark of the airline's brand identity. This attention to detail speaks volumes about ANA's dedication to customer satisfaction and its willingness to invest in distinctive marketing efforts.
Swiss International Air Lines (SWISS) is another carrier that has made significant commitments to quad-engine aircraft. With four A340-300s in service, SWISS operates on long-haul routes, leveraging the efficiency of these engines to deliver high-quality services to its passengers.
However, SWISS's A340 fleet is expected to be phased out in the coming years, as new Airbus A350-900s take their place. This transition reflects the industry's ongoing shift towards more efficient and environmentally friendly aircraft designs.
Air China is one of the last remaining operators of the Boeing 747, with a fleet of five 747-400s and two 747-8s in commercial passenger service. As this iconic aircraft prepares to retire, Air China must navigate a changing market landscape.
The airline's decision to phase out its 747 fleet marks an important milestone in the industry's transition towards more modern designs. With its remaining 747-400s set to be retired soon, Air China will need to adapt quickly to meet evolving passenger demands and regulatory requirements.
The decline of four-engine passenger jets is a significant shift in the aviation industry, with far-reaching implications for fuel efficiency and emissions.
