Jet-A Market Analysis in Illinois
We track Jet-A pricing at 19 FBOs across 16 airports in Illinois. The cheapest Jet-A is $6.50/gal at Flightline (KMDH), while the most expensive runs $10.34/gal at KMDW — a spread of $3.84/gal. 12 FBOs are priced below the state average of $8.05/gal. On a typical 180-gallon turbine top-off, fueling at the cheapest FBO instead of the state average saves about $279.
Jet-A prices move with crude markets, supplier contracts, airport competition, and volume discounts. Full-service fueling carries an into-plane fee that self-serve avoids, so comparing both is worthwhile on longer fills. Rankings update daily from AirNav FBO reports.
