The MCX program is a worldwide, aggregated, de-identified database of aircraft maintenance costs, maintenance programs, personnel and overhead costs.

Need Help?

MCX provides the tools, the methodology and the definitions to determine how much it costs an airline to maintain its fleet and support decisions in cases of new fleet introduction or expansion, “make vs. buy” assessment, year-over-year trends, etc.

We collect maintenance cost data from more than 50 airlines worldwide (representing about a quarter of the world’s fleet and MRO spend) on an annual basis.

Free tools for MCX contributors

Tools and reports are free and exclusive to airlines who contribute their aircraft maintenance cost data to the program.

Web-based Dashboard and Query Tool


Easy access to aircraft maintenance cost data:

  • By aircraft & engine type
  • By region
  • By airline fleet size
  • Per flight hour, per flight cycle, per AC
  • By segments (line, base, component, engine)
  • By segments (labor, material, subcontracted)

Comprehensive Analyses


Participating airlines receive the annual IATA Maintenance Cost Report with SME insights, benchmark data, key performance indicators and 5-year trend analysis. A document worth distributing throughout your organization.
