What You'll Learn
The price of jet fuel
The type of aircraft, sector length, and weather conditions all impact how much fuel is required for a flight, and therefore the overall fuel cost. For example, a Boeing 747 uses approximately 1 gallon (4 litres) of fuel per second, burning 36,000 gallons (150,000 litres) of fuel over a 10-hour flight. The Airbus A380, the world's largest jet airliner, is more fuel-efficient, burning 4,600 gallons (11,400 litres) of fuel per hour.
The direction of travel also affects fuel costs, with eastward flights capitalising on the jet stream, resulting in lower fuel costs compared to the reverse direction. Additionally, fuel prices may be influenced by taxes and mandates, such as the European Union's fuel blending mandates.

How much fuel is used per flight
The amount of fuel used per flight depends on several factors, such as the type of aircraft, the length of the sector, and the weather. For example, a Boeing 747 uses approximately 1 gallon (about 4 litres) of fuel every second, burning about 36,000 gallons (150,000 litres) of fuel over a 10-hour flight. On the other hand, the Airbus A380, the world's largest jet airliner, burns an average of 4,600 gallons (11,400 litres) of fuel per hour, which is more than the 747.
The direction of travel also affects fuel consumption, as aircraft flying eastward can take advantage of the jet stream, resulting in significantly lower fuel costs compared to the reverse direction. Additionally, the length of the flight is a factor, as longer flights require more fuel. For instance, a flight to Hong Kong may use up to 96% of its fuel just for cruising, while a shorter flight to Paris might only use 62% for cruising.
The number of passengers on a flight also impacts fuel efficiency. The Airbus A380, with a capacity of over 800 passengers, offers a 20% increase in per-passenger fuel efficiency compared to the older 747. This means that on a flight with 200 passengers, each person's fuel consumption is reduced.
It's worth noting that some airlines opt to fill up with enough fuel for a round trip, while others refuel on the return journey, which can impact the overall fuel efficiency of the flight. Fuel prices and availability at different airports also play a role in an airline's fuelling strategy.
While it is challenging to calculate the exact cost per aircraft on average per flight due to fluctuating fuel prices and varying fuel consumption rates among aircraft, it is clear that fuel is a significant expense for airlines, accounting for 20-40% of their expenditure.

Fuel as a cost for airlines
Fuel is a significant expense for airlines, accounting for a large percentage of their overall spending. The price of jet fuel is closely tied to the price of oil, which fluctuates daily, and is also influenced by global politics. As such, fuel prices are subject to constant change and are largely beyond the control of airlines. This volatility in the market poses a challenge for airlines in managing their costs.
The amount of fuel required by each flight varies depending on factors such as aircraft type, sector length, and weather conditions. For example, a Boeing 747 burns approximately one gallon of fuel per second, resulting in 36,000 gallons of fuel burned over a 10-hour flight. On the other hand, the Airbus A380, the world's largest jetliner, burns approximately 4,600 gallons of fuel per hour. These differences in fuel efficiency between aircraft types contribute to the varying fuel costs for airlines.
Airlines employ different strategies when it comes to fuelling their aircraft. Some airlines opt to refuel their planes only on the return journey, while others fill up enough fuel for a round trip or even 1.5 trips. Refuelling a plane can be a complex and time-consuming process, especially for a full tank top-up, impacting the turnaround times. Additionally, fuel prices can differ between airports, with shorter flights sometimes opting to refuel at their home airport if fuel is cheaper there.
The cost of fuelling a commercial flight can vary significantly depending on the route and the type of aircraft. For example, the fuel cost for a flight between New York JFK and London Heathrow was estimated at $27,270, while the fuel cost for a flight between JFK and Los Angeles International Airport was $10,757. The direction of travel also plays a role, with eastward flights benefiting from the jet stream and resulting in lower fuel costs compared to the reverse direction.
The price of jet fuel, specifically Jet A1, has undergone fluctuations in recent years. In January 2022, the price was approximately $816 per metric tonne, or $0.82 per KG, which was nearly double the price in January 2021. At its lowest, in May 2020 due to the collapse in oil prices caused by the Covid-19 pandemic, Jet A1 fuel was priced at around $200 per metric tonne, or $0.20 per KG. These price variations have a direct impact on the overall fuel expenditure of airlines.

How plane size impacts fuel usage
The cost of aeroplane fuel is a significant expense for airlines, accounting for 20-40% of their expenditure. Fuel prices are subject to market fluctuations and are influenced by global politics. The type of aircraft, sector length, and weather are some factors that determine how much fuel is required for a flight.
The size of an aircraft plays a crucial role in fuel usage. Larger planes, such as the Airbus A380, burn more fuel per hour than smaller planes. For example, the Airbus A380, the world's largest jet airliner, burns approximately 4,600 gallons of fuel per hour, while a smaller plane like the Boeing 747 burns about 36,000 gallons of fuel during a 10-hour flight. The number of seats and the maximum take-off weight (MTOW) contribute to higher fuel consumption in larger aircraft.
However, when considering fuel efficiency, larger planes can be more efficient on a per-passenger basis. For instance, the Airbus A380 can carry over 800 passengers, resulting in a 20% increase in per-passenger fuel efficiency compared to the older Boeing 747. This means that, while the total fuel burn is higher for larger planes, the fuel burn per passenger can be lower.
The design of an aircraft also impacts fuel usage. Subsonic turboprop aircraft, such as the Bombardier Dash 8 Q400, are more fuel-efficient than transonic turbofan aircraft. By reducing the speed and using turboprop propulsion, aircraft can achieve significant fuel savings. Additionally, wingtip devices can improve the lift-to-drag ratio, resulting in increased fuel efficiency.
Other factors that influence fuel usage include the aircraft's empty weight, payload weight, engine efficiency, flight path, and weather conditions. The stage of flight, such as taxiing, takeoff, climb, cruise, and approach, also affects fuel consumption, with cruising typically being the most fuel-intensive stage for long-haul flights.

How fuel prices have changed over time
The price of aeroplane fuel, or jet fuel, has changed significantly over time, with several factors influencing its cost. Jet fuel prices are directly linked to crude oil prices, as crude oil is the primary raw material used in the refinement process to create aviation-grade fuel. While the price of jet fuel is not identical to crude oil due to the added costs of refinement, the difference between the two, known as the crack spread, has been a critical factor in determining jet fuel prices.
Historically, the crack spread was maintained at under $20 per barrel, with fluctuations during periods of economic growth or stagnation. However, in recent years, the crack spread has spiked, causing fuel costs to become more unpredictable. Environmental regulations have also contributed to higher refining costs, resulting in increased jet fuel prices. These market shifts, influenced by factors like global conflicts and regulations, have created uncertainty for airlines regarding future fuel expenses.
The volatile nature of jet fuel prices poses challenges for airlines, as fuel is one of their most significant expenses, accounting for 20-40% of their expenditure. The unpredictable and frequent changes in fuel costs make it difficult for airlines to plan their expenses effectively. For instance, in 2008, jet fuel prices underwent significant swings, starting at $2.714 per gallon in January, rising by 54% to $4.179 per gallon in six months, and then plummeting by 71% to $1.202 by December.
To mitigate the risks associated with volatile jet fuel prices, airlines have implemented fuel hedging programs. These strategies allow airlines to lock in fuel prices at a specific level, protecting them from sudden spikes. However, the effectiveness of these hedging programs can be limited due to the dynamic nature of the fuel market. Additionally, factors such as aircraft type, sector length, and weather conditions also impact fuel consumption and costs.
The price of jet fuel also varies across regions and airports, influenced by factors such as local taxes, fuel mandates, and the availability of suppliers. Some airlines opt to refuel only on their return journey, while others fill up enough fuel for a round trip or 1.5 trips, depending on the length of the sector and the cost of fuel at the destination airport. Ultimately, jet fuel prices have fluctuated significantly over time, influenced by a range of economic, political, and environmental factors, presenting a constant challenge for airlines to manage their fuel expenses effectively.
