Fuel costs as a proportion of airline expenses
Fuel costs are a significant expense for airlines, accounting for a large percentage of their total expenses. The proportion of expenditure on fuel varies depending on price and region, ranging from 15 to 40% of total expenses. For example, United Airlines spent $8.9 billion on aircraft fuel in 2019, approximately 23% of its total expenses that year. IndiGo, a low-cost carrier, saw its fuel costs rise by 6.5% in Q4 FY24 to $713.8 million, while Singapore Airlines spent $987 million on fuel in Q2 of 2021, representing 28.8% of its half-year expenditure.
Fuel costs for airlines are subject to market fluctuations and are influenced by global politics, aircraft type, sector length, and weather conditions. Airlines have limited control over fuel costs and often use fuel hedging to protect themselves against market volatility. However, this tactic can also trap them in high-price cycles, as seen during the pandemic. The price of jet fuel has a direct impact on ticket prices, and airlines pass on some of the fuel-related costs to consumers through fuel surcharges.
The aviation industry's fuel usage and spending plummeted during the pandemic but rebounded in 2022. Fuel use worldwide rose to 77 billion gallons in 2022, a 48% increase from 2020 but still below pre-pandemic levels. Fuel prices have also increased, with a similar fuel volume in 2023 costing 43% more than in 2019. These price increases have been attributed to global conflicts, such as the war in Ukraine, which drove up prices of petroleum and natural gas.
While aircraft do not typically fill their tanks to maximum capacity due to efficiency concerns, the decision on fuel load depends on the airline's strategy. Some airlines opt for enough fuel for a round trip, while others refuel on the return journey. Fuel prices for airlines are relatively stable compared to gas stations, as there is less price competition among the select group of suppliers serving the aviation industry.

Fluctuating fuel prices
Fuel costs are one of the largest expenses for airlines, accounting for between 15 and 40% of their total expenses. The price of fuel is subject to market fluctuations, influenced by global politics and other factors such as aircraft type, sector length, and weather. This volatility in fuel prices has a direct impact on the price of airline tickets, as airlines pass on some of the fuel-related costs to consumers through fuel surcharges.
For example, United Airlines spent $8.9 billion on aircraft fuel in 2019, which accounted for approximately 23% of its total expenses. In 2023, the airline's fuel bill was $3.32 billion, which was on par with the cost in 2022. However, the full-year expense of fuel in 2023 was $12.651 billion, a 3.5% decrease from the previous year. IndiGo, a low-cost carrier, saw its fuel costs rise by 6.5% in Q4 FY24, while Singapore Airlines spent $987 million on fuel in Q2 of 2021, representing 28.8% of its half-year expenditure.
The aviation industry's fuel usage and spending plummeted during the pandemic, but rebounded in 2022. Fuel prices, however, remained high. According to the International Air Transport Association (IATA), fuel prices in 2023 were 43% higher than in 2019, and they are forecast to increase further in 2024. These increases have been attributed to global conflicts, such as the war between Russia and Ukraine, which drove up prices of commodities linked to petroleum and natural gas.
Airlines have different strategies for fueling up, with some opting for enough fuel for a round trip while others choose to refuel only on the return journey. Refueling on the return journey can be complex and delay turnarounds, especially for a full tank top-up. Additionally, fuel prices can vary between airports, with shorter flights sometimes opting to refuel at their home airport where fuel may be cheaper.
While the price of jet fuel has a significant impact on airline ticket prices, it is important to note that other factors, such as labor costs and sustainability initiatives, also play a role in the overall cost of air travel.

Fuel surcharges passed on to customers
Fuel is a major expense for airlines, accounting for 15 to 20% of their total expenses, or even as much as 40% depending on price and region. As a result, airlines are incentivised to pass on these costs to their customers. The price of jet fuel directly impacts the price of an airline ticket.
Some airlines, such as United Airlines, Singapore Airlines, and Avianca, do not pass on fuel surcharges to their customers. Singapore Airlines, for example, does not charge fuel surcharges on its own flights, nor does it pass on fuel surcharges from some of its partners, including United Airlines. Avianca's LifeMiles program also does not pass on fuel surcharges.
However, many airlines do pass on fuel surcharges to their customers, especially for award tickets. Iberia, for instance, passes on $850 in one-way fuel surcharges and $1,700 in round-trip fuel surcharges for business class flights between the U.S. and Spain. For economy, the fuel surcharges are $160 one-way and $320 round-trip. Scandinavian Airlines (SAS) also passes on fuel surcharges for business class and economy tickets, charging $1,700 and $320 for round-trip flights between the U.S. and Europe, respectively. British Airways, Emirates, and Lufthansa are also known for high fuel charges.
Fuel surcharges can make up a majority of the fare. For example, a $572 round-trip ticket from New York to London on JetBlue has a base fare of $0.50 per direction, while the carrier-imposed surcharges are $320. These surcharges are particularly common when redeeming miles and points, as some programs and airlines do pass on these surcharges to consumers.

Fuel usage and spending during the pandemic
Fuel is a major expense for airlines, accounting for 15 to 20% of their total expenses, according to the US Department of Transportation. Airlines spent $3 billion on fuel in July 2019, a 4% decrease from 2018. However, the pandemic caused a significant drop in the aviation industry's revenues, fuel usage, and spending. During the pandemic, fuel prices dropped below $0 a barrel, causing a collapse in the fossil fuel industry.
Despite the decrease in fuel prices during the pandemic, airlines were trapped in high-price cycles due to fuel hedging, a tactic used to protect against market fluctuations. As a result, airlines were unable to take advantage of the low fuel prices. In 2022, fuel usage rebounded, with fuel use for all airlines worldwide reaching 77 billion gallons, a 48% increase from 2020. However, fuel prices continued to rise, and it is predicted that fuel prices in 2024 will be 53% higher than in 2019.
The increase in fuel prices is attributed to several factors, including the war in Ukraine and the conflict between Israel and Palestine, which have driven up prices of commodities linked to petroleum and natural gas. Additionally, the cost of fuel for airlines is influenced by various factors such as aircraft type, sector length, and weather conditions. Airlines have different strategies for fueling, with some opting for enough fuel for a round trip while others choose to refuel on the return journey.
The impact of fuel prices on airlines is significant, as it directly affects the price of airline tickets. With rising fuel costs, passengers can expect higher fares. Furthermore, fuel is an expense that airlines have little control over and is subject to constant market fluctuations, making it a challenging aspect of the industry.
