Key Takeaways, KAPA monthly fuel volumes through March 2025:

• DEFINITIONS: ‘AvGas’ is the fuel used for most prop planes, and has two types: ‘LL’ = low-lead, ‘UL’ = unleaded. 'Running-Sum’ adds the most recent 12-months.
  
  • ’Fuel Flowage’ includes both ‘sales’ (to outsiders, buying the fuel) and ‘non-sales’ (to in-fleet planes, such as for FBO aircraft used for rental or flight training).
    
  • 'ATADS’ is FAA’s definitive air traffic count program, recorded by ATC; ‘OPS’ = ops per month; ‘ITIN’ = itinerant (non-local) flights; ‘LCL’ = local (mostly closed pattern) flights.
    
• 1-Year Change, 12-month running-sum fuel volumes through March 2025: jetfuel was down 1%; AvGas (100LL plus 94UL, for small prop planes) was up 2%.
  
• Seasonality: AvGas volume tends to be heaviest in August, lightest in January; jet fuel volume tends to be heaviest in summer/fall, slowest in winter/spring.
  
• Red-Blue Colorscale: applied to running-sum volume data, red (20% higher than overall monthly average) vs. blue (20% lower).
  
• Orange-Green Colorscale: applied to year-to-year change in running-sum volume data, orange (20% higher than monthly average) vs. green (20% lower).
  
• COVID IMPACT: AvGas was virtually unchanged, but jetfuel saw reductions averaging 15% (followed by a rebound summer 2021 through fall 2022).
  
• Jetfuel volume through March 2025 is 1.1% higher than the pre-COVID total through February 2020; for the same timeframe, AvGas volume is up 13.2%.
  
• Unleaded fuel volume: sales of Swift 94UL fuel were begun in May 2023, but the airport authority has not yet arranged sales of GAMI100UL fuel.
  
• 94UL volume peaked at 25% of all AvGas in January and November 2024, and was roughly 16% of all AvGas in March 2025.
  
• How much lead (Pb) pollution? There is one pound of lead in each 214 gallons of 100LL. So, in the year ending March 2025, fuel volume included 2,745 pounds of lead.
  
• Lead pollutants peaked at 3,152 pounds/year in May 2022; as of March 2025, 94UL sales have achieved a 13% net reduction of lead, to 2,745 pounds/year.
  
• Note that the three primary airport revenue sources are fuel flowage fees, usage fees (for landing, overnight parking, etc.), and leases (hangars and/or ground space).
  

As set by the airport authority, fuel flowage fees are 10cts/gal AvGas and 15cts/gal jetfuel; most aircraft pay zero landing fees.
