AFF: Aircraft Fleet Age by Airline Carrier

Aviation Facts & Figures data tracks the age composition of aircraft fleets for individual U.S. airlines over time. Columns include the number of aircraft, youngest, oldest, and average age, plus corresponding years of manufacture for each carrier annually. This dataset allows for longitudinal analysis of fleet modernization, carrier investment cycles, and operational planning.

Use Cases

• Benchmarking fleet modernization between carriers using UNIQUE_CARRIER_NAME, Average Age, and YEAR.
• Analyzing capital investment cycles by tracking Youngest Year of Manufacture and Oldest Year of Manufacture over time.
• Estimating maintenance cost trends by correlating Average Age with Number Of Aircraft for specific carriers.
• Modeling fleet replacement schedules using trends in Youngest Age and Oldest Age across multiple years.

Strengths

• Cross-platform presence on Socrata and Data.gov signals established importance and reliability.
• Provides detailed age metrics at the carrier-year level, enabling granular comparative analysis.

Limitations

• Metadata conflicts: license is listed as 'other-license-specified' on some sources but 'None' on others, and row counts are universally unknown.
• Limited documentation on data collection methodology and the definition of 'carrier' is not provided.
