Jet fuel is cheaper than gasoline primarily because it costs less to refine, carries far lower taxes, and sells through a simpler distribution chain. At the wholesale level, the price gap between the two fuels is modest, often just cents per gallon. But once you factor in the taxes and retail markup that get layered onto gasoline at the pump, the difference widens considerably.
Gasoline Takes More Work at the Refinery
Crude oil refining begins in distillation towers, where heat separates the oil into groups of hydrocarbons based on their boiling points. Jet fuel (specifically Jet A, the standard for commercial aviation) sits in the kerosene boiling range and is produced mostly by blending straight-run distillates, the fractions that come directly off the tower without much additional processing. Refiners generally avoid putting cracked or chemically altered components into jet fuel because those contain compounds that make the fuel burn less cleanly.
Gasoline is a different story. It requires extensive secondary processing to raise its octane rating, the measure of how well it resists knocking in an engine. Refiners run lighter fractions through catalytic reforming and catalytic cracking, both energy-intensive processes involving high temperatures, elevated pressures, and platinum-based catalysts. The general rule in refining is that higher severity means higher cost, and gasoline demands that severity. Jet fuel largely skips it.
The yield numbers reflect this imbalance. A standard 42-gallon barrel of crude oil produces roughly 47% finished motor gasoline but only about 11% kerosene-type jet fuel. That massive gasoline output requires a much larger share of the refinery’s conversion infrastructure, driving up its per-gallon production cost relative to jet fuel’s more straightforward path from crude to finished product.
Taxes Create the Biggest Price Gap
The single largest reason jet fuel is cheaper than gasoline at the point of sale is taxation. In the United States, gasoline carries a federal excise tax of 18.4 cents per gallon plus an average of 32.6 cents per gallon in state taxes, for a combined tax burden of roughly 51 cents on every gallon. That tax revenue funds road construction and maintenance, so it’s tied directly to the infrastructure cars and trucks use.
Jet fuel used for commercial aviation faces a completely different tax structure. Domestically, airlines pay a federal excise tax on the fuel itself, but it’s significantly lower than the road-use tax on gasoline. Internationally, the picture is even more favorable for airlines. The 1944 Chicago Convention on International Civil Aviation, through Article 24(a), exempts fuel on board an aircraft from customs duties and similar national charges. A 1999 resolution from the International Civil Aviation Organization expanded this exemption to cover “import, export, excise, sales, consumption and internal duties and taxes of all kinds” on fuel taken on board for international flights. Most U.S. bilateral air services agreements mirror this language. The result: fuel burned on international routes is largely tax-free, a policy designed to prevent countries from competing to tax each other’s airlines and to keep the global aviation system functional.
For a practical comparison, consider that taxes alone add roughly $0.51 to every gallon of gasoline in the U.S. Even a modest reduction in that figure for jet fuel translates into a meaningful per-gallon savings when multiplied across the thousands of gallons a single commercial flight burns.
Bulk Delivery vs. Retail Infrastructure
Gasoline reaches consumers through one of the most expensive distribution networks in the energy industry. Fuel travels from refineries to regional terminals, then onto tanker trucks that deliver to thousands of individual retail stations across the country. Each station carries its own real estate costs, employee wages, equipment maintenance, insurance, and regulatory compliance. All of those costs get baked into the price per gallon at the pump.
Jet fuel, by contrast, moves through a far leaner supply chain. It flows from refineries to a relatively small number of airports, often through dedicated pipelines or in large bulk shipments. At the airport, fuel is stored in centralized tank farms and delivered to aircraft through hydrant systems built into the tarmac or by a small fleet of fuel trucks. There’s no retail storefront, no credit card transaction fees from millions of individual customers, and no competition for prime roadside real estate. Wholesale pricing typically runs 10 to 30% below retail for this reason alone, and airlines are the ultimate bulk buyers, purchasing millions of gallons under long-term contracts that lock in volume discounts.
Additive Costs Slightly Favor Jet Fuel
Both fuels require additives, but gasoline’s additive package is more complex and more regulated at the consumer level. U.S. gasoline must contain detergent additives to meet EPA deposit-control standards, and most gasoline sold in the country is blended with roughly 10% ethanol, a renewable fuel mandate that adds both cost and logistical complexity (ethanol can’t travel through regular pipelines because it absorbs water, so it’s blended at the terminal).
Jet fuel additives are fewer in number. The main ones are anti-icing agents (fuel system icing inhibitors) that prevent ice crystals from forming at high altitude, antioxidants, and anti-static compounds. These are important for flight safety but represent a simpler and generally less expensive additive package than what gasoline requires. Jet A also has a freezing point specification of minus 40°C (the colder-rated Jet A-1 used on many international routes is minus 47°C), which is managed partly through additive chemistry and partly through the natural properties of kerosene-range hydrocarbons.
What the Price Difference Actually Looks Like
At the wholesale level, the gap between jet fuel and gasoline is surprisingly narrow. Both fuels track crude oil prices closely, and their spot prices at major trading hubs like the New York Harbor or Gulf Coast often sit within 10 to 30 cents of each other. In early March 2026, wholesale gasoline (RBOB) was trading around $2.28 to $2.84 per gallon depending on the region. Jet fuel spot prices tend to track in a similar range, sometimes slightly below, sometimes slightly above, depending on seasonal demand.
The dramatic price difference shows up when you compare what airlines actually pay per gallon to what drivers pay at the pump. A driver filling up might pay $3.20 or more after taxes and retail markup. An airline buying jet fuel in bulk at an airport might pay closer to $2.30 to $2.60. That gap of 60 cents to a dollar per gallon comes almost entirely from three things stacked on top of each other: higher taxes on gasoline, retail distribution costs, and the markup that keeps gas stations in business.
Seasonal patterns also play a role. Gasoline demand spikes every summer as Americans drive more, pushing prices higher. Jet fuel demand is steadier year-round, which means it avoids the worst of those seasonal price surges. During winter, jet fuel demand can actually rise (holiday travel, heating oil competition for similar distillate fractions), but the swings are generally less dramatic than gasoline’s summer peaks.
