Top 10 ACMI dedicated airlines in the world 

SmartLynx Airlines

Aircraft, crew, maintenance, and insurance, widely known as “ACMI” services, are currently considered the most common method of outsourcing operations for airlines.  

The ACMI operations model is the popular aviation equivalent of dialing an Uber in the automotive industry. However, instead of a car, a client would have access to private jet or commercial aircraft for a designated period without large capital investment, maintenance issues, or operational hassles.  

Market forecasts conducted by aircraft manufacturers estimate demand for 43,000 new commercial passenger and freighter aircraft by 2042.   

The rising global demand for ACMI services across passenger and cargo operations is predicted to become a key factor in an expected revenue increase.  

AeroTime has compiled a list of 10 airlines and airline groups that could be considered leaders in the global market in terms of aircraft fleet size.
