The cost of aviation fuel is a significant expense for airlines, accounting for 20-40% of their total expenses. The price of jet fuel, which is used by most US airlines, is influenced by the global price of crude oil and is subject to market fluctuations. Various factors, such as aircraft type, sector length, and weather, impact fuel consumption per flight. While exact costs are challenging to determine due to constant price fluctuations, estimates provide insight into the fuel expenses for specific routes. For example, a flight from New York JFK to London Heathrow incurs an estimated fuel cost of $27,270.

Fuel costs vary by region and aircraft type
Fuel is a significant expense for airlines, accounting for 20-40% of their total expenditure. The cost of aviation fuel varies by region and aircraft type due to several factors, including global politics, sector length, weather conditions, and airport location.
For instance, on May 11, 2022, the IATA per-gallon price was $4.82 in North America, $4.01 in Europe, and $3.55 in Asia. Additionally, jet fuel prices can differ within the same region, such as the example of Boston's Hanscomb Field Jet A fuel, which ranged from $9.79 to $13.38 per gallon, compared to $7.05 per gallon in Oklahoma City.
The type of aircraft also influences fuel costs. Different planes have varying fuel consumption rates, with light jets consuming between 134 and 222 gallons of jet fuel per hour. As an example, the Bombardier Global 7500, an ultra-long-range private jet, burns 528 gallons per hour, while the Embraer Phenom 300 light jet consumes 183 gallons per hour.
Furthermore, the direction of travel can also impact fuel costs. Aircraft flying eastward can take advantage of the jet stream, resulting in significantly lower fuel costs compared to the reverse direction.
While exact calculations of fuel costs per aircraft and flight are challenging due to constant market fluctuations, fuel remains a critical and volatile expense for airlines, with limited control over pricing.

Fuel prices fluctuate constantly
The type of aircraft, sector length, and weather conditions all play a role in determining fuel requirements and, consequently, fuel costs. For example, a Boeing 747-400 burns around 10-11 tons of jet fuel per hour, while shorter flights using a Boeing 737-800 consume about 2.5-3 tons per hour. Additionally, the direction of travel matters, as aircraft flying eastward can take advantage of the jet stream, resulting in lower fuel costs compared to the reverse direction.
The price of jet fuel, a petroleum product, is heavily influenced by the global price of crude oil. Global politics and market fluctuations also contribute to the volatility in fuel prices. Furthermore, taxes, fuel mandates, and the limited number of suppliers in the aviation industry can impact fuel costs.
Airlines employ different strategies to manage fuel costs. Some airlines opt for enough fuel to cover a round trip, while others refuel only on the return journey, especially if fuel is cheaper at their home airport. These factors make it challenging to calculate the exact fuel cost per aircraft or flight.

Fuel is a major expense for airlines
Several factors determine how much fuel a flight requires, including aircraft type, sector length, and weather conditions. Different aircraft have varying fuel consumption rates, with larger planes like the Airbus A380 using around 11-12 tons of fuel per hour, while smaller planes like the Airbus A320 burn around 2.5 tons per hour. Airlines also have different strategies for refuelling, with some opting to fill up enough for a round trip, while others may only refuel on the return journey, depending on fuel prices at each airport.
The direction of travel can also impact fuel costs, with eastward flights capitalising on the jet stream and resulting in lower fuel usage. Taxes and fuel mandates, such as blending requirements, can further affect the cost of aviation fuel. Additionally, unlike petrol stations, there is less competition among fuel suppliers for airlines, limiting their options.
While exact calculations are challenging due to constant price fluctuations, some pre-pandemic data provides insights into average fuel costs for specific routes. For example, a flight from New York JFK to London Heathrow had an average fuel cost of $27,270, while the fuel cost for a flight from JFK to Los Angeles International Airport was $10,757.

Airlines have different refuelling strategies
Fuel is a significant expense for airlines, accounting for 20-40% of their total expenditure. The price of jet fuel is subject to market fluctuations influenced by global politics, making it a cost that airlines have little control over. Aircraft type, sector length, and weather conditions are some of the factors that determine the amount of fuel required for a flight.
Given the high costs and dynamic nature of fuel pricing, airlines have developed different refuelling strategies. Some airlines opt to fill up with enough fuel for a round trip, while others choose to refuel only on the return journey. Refuelling on the return journey can be more cost-effective, especially for shorter flights where fuel is cheaper at the home airport. However, this strategy can delay turnarounds, especially when a full tank top-up is required.
Airlines operating at regional airports often rely on contracts with fixed-base operators (FBOs) to meet their fuelling needs. These FBOs deliver fuel via trucks instead of using underground pipelines, which are more common at larger airports. The flexibility of FBOs helps smaller regional airports with modest infrastructure maintain smooth operations.
Most airlines outsource fuelling operations to independent operators based at the airport. These contractors not only handle fuelling but also provide other services such as lavatory maintenance and general upkeep. Fuel load information is typically provided to these operators 45 to 60 minutes before a domestic flight's departure. In certain cases, pilots may directly inform the fuelling agency about their kerosene requirements, which is more common in general aviation or with corporate pilots.
The process of refuelling involves accessing the aircraft's fuelling panel, which can vary depending on the aircraft's design. Most planes have a simple intake system, while some advanced aircraft can automatically distribute fuel between their tanks. For planes with multiple auxiliary or trim tanks, pilots may need to open crossfeed valves to ensure an even fuel distribution.

Jet fuel is a kerosene-based product
The cost of fuelling a commercial airliner depends on a variety of factors, including the type of aircraft, sector length, and weather conditions. Fuel prices also fluctuate constantly and are influenced by global politics and market volatility. As such, it is challenging to calculate the exact cost of fuelling a commercial aircraft on average per flight.
Jet fuel, which powers most commercial aircraft, is a kerosene-based product. Kerosene-based jet fuel typically has a carbon number distribution of about 8 to 16 carbon atoms per molecule. The exact composition of jet fuel can vary widely depending on the petroleum source, and it may contain numerous aliphatic and aromatic hydrocarbon compounds, including toxicants such as benzene, n-hexane, toluene, and xylenes.
The performance specifications of jet fuel are defined by the requirements for the product, such as the freezing point or smoke point. The aviation industry's demand for jet kerosene has increased, leading refiners to optimise yield by varying process techniques and exploring alternative sources, such as coal tar sands.
To meet health and safety standards, additives are often included in jet fuel. For example, metal deactivators can be added to reduce the negative effects of trace metals on the thermal stability of the fuel. Additionally, oxidation inhibitors are typically present in kerosene-based jet fuels to enhance their performance characteristics.
The cost of jet fuel varies across regions and is influenced by factors such as supply and demand, taxes, and fuel mandates. As a result, the price of fuelling a commercial flight can differ significantly depending on the origin and destination airports.
