Fuel use depends on aircraft size and efficiency
The fuel efficiency of an aircraft is influenced by various factors, including aerodynamics, weight, engine brake-specific fuel consumption, propulsive efficiency, and thrust-specific fuel consumption. Newer aircraft are often more fuel-efficient due to advancements in technology, such as higher pressure and bypass ratios, geared turbofans, and hybrid electric propulsion systems. Additionally, the design of the aircraft plays a role in fuel efficiency, with twin-engine aircraft like Boeing's 787 and Airbus's A350 being more fuel-efficient than larger four-engine aircraft like the Boeing 747 and Airbus A380.
The Boeing 737-800, a popular narrow-body aircraft, benefits from the use of winglets, which can increase efficiency by up to 10.5%. Winglets improve the lift-to-drag ratio by reducing lift-induced drag caused by wingtip vortices. This results in a more efficient flight and can lead to significant fuel savings.
The cost of fuelling a 737-800 depends on various factors, including the price of jet fuel, the efficiency of the aircraft, and the duration of the flight. While the exact fuel consumption of a 737-800 may vary, estimates suggest that the full cost per hour, including fuel, plane, maintenance, and staff, is around $5,500. Therefore, the cost of fuelling a 737-800 for a typical flight would depend on the duration and the price of jet fuel at the time.
In summary, fuel use in aircraft is influenced by size and efficiency, with larger aircraft generally consuming more fuel. However, advancements in technology and design have led to improvements in fuel efficiency, and the use of winglets can further enhance efficiency. The cost of fuelling a 737-800 depends on various factors and can vary depending on the specifics of each flight.

Airlines have different strategies for refuelling
Refuelling a 737-800 can cost around $5500 per hour, including fuel, plane, maintenance, and staff. While the cost of jet fuel is only a few dollars extra per gallon than regular automobile fuel, the total refuelling cost depends on various factors, such as the fuel capacity and efficiency of the aircraft, the distance travelled, and the price of fuel, which varies across locations and over time.
Airlines employ different strategies for refuelling their aircraft, and these strategies have evolved over time with advancements in technology and changing operational requirements. One key strategy is optimising refuelling schedules to minimise costs and maximise efficiency. Airlines analyse flight routes, aircraft performance, and fuel prices at different airports to determine the most cost-effective refuelling points. By refuelling at airports with lower fuel prices or taking advantage of favourable fuel rates at specific locations, airlines can significantly reduce their overall fuel expenses.
Another strategy involves the use of fuel-efficient aircraft and technologies. Airlines may invest in newer, more fuel-efficient models or retrofit existing aircraft with fuel-saving devices and systems. Optimising aircraft weight, utilising efficient flight paths, and employing fuel-efficient flight procedures also play a crucial role in reducing fuel consumption and costs.
Some airlines have adopted innovative refuelling techniques, such as single-point refuelling systems, which streamline the refuelling process, reducing the time and manpower required. Additionally, the use of data analytics and digital platforms enables airlines to optimise fuel management by analysing fuel usage patterns, identifying inefficiencies, and making data-driven decisions to refine their refuelling strategies.
In certain situations, aerial refuelling, or in-flight refuelling, has been employed, especially in military operations. This technique involves refuelling aircraft while they are airborne, extending their range and endurance. While aerial refuelling is not commonly used in civilian aviation due to the associated costs and equipment requirements, it has been utilised in specific scenarios, such as during the Vietnam War, to enable aircraft to cover long transoceanic distances without intermediate landings.

Fuel prices are influenced by global politics
The cost of fuelling a 737-800 varies depending on various factors, but a rule of thumb shared by a user on Reddit in 2017 estimated the full cost per hour of a 737-800 to be about $5500, including fuel, plane, maintenance, and staff.
Now, onto how fuel prices are influenced by global politics. Fuel prices, particularly for oil and natural gas, are influenced by global politics in several ways. Firstly, the Organisation of the Petroleum Exporting Countries (OPEC), a group of oil-producing nations, can decide to increase or decrease oil production in response to political or economic circumstances, directly impacting oil prices. For example, when OPEC reduces production due to oversupply or falling prices, global energy costs tend to rise.
Secondly, maritime routes are critical for transporting oil and liquefied natural gas. However, these routes are vulnerable to geopolitical tensions, wars, piracy, and sanctions, leading to restricted energy resources and significant price volatility. For instance, when Russia invaded Ukraine in 2022, international reactions caused oil and gas prices to soar.
Thirdly, the political relationships and tensions between powerful countries, such as the US and China, can significantly affect oil prices. Positive developments in their relationship, as well as higher geopolitical risks, tend to drive up oil prices. Additionally, when oil-exporting nations face budgetary constraints, they may cut subsidies, leading to increased domestic fuel prices and reduced global demand, influencing international energy prices.
Lastly, government policies and investments in renewable energy can also impact fuel prices. While these policies reduce long-term dependence on fossil fuels, they can cause short-term market volatility. Governments may also offer tax incentives to promote cleaner energy, affecting the supply and demand dynamics of traditional fuels.

Jet fuel is only slightly more expensive than regular automobile fuel
The cost of fuelling a 737-800 depends on several factors, including the price of jet fuel, the fuel efficiency of the aircraft, and the duration of the flight. According to some estimates, the full cost per hour of operating a 737-800, including fuel, plane maintenance, staff, etc., is about $5500 per hour.
Regarding jet fuel costs, it is important to note that jet fuel prices can vary globally and over time due to various factors such as supply and demand, production costs, and taxes. For example, the global average jet fuel price rose 0.5% from the previous week to $90.21 per bbl recently.
Now, while jet fuel is generally more expensive than regular automobile fuel, the price difference may not be as significant as one might expect. In some regions, jet fuel is only a few dollars extra per gallon than regular automobile fuel. For instance, in India, Aviation Turbine Fuel (ATF), which is used to fly aircraft, costs ₹79 per litre in Delhi, while petrol costs ₹105.84, and diesel costs ₹94.57 for the same amount.
The price difference can be attributed to several factors, including the way taxes are calculated for different types of fuel. In many places, jet fuel and automobile fuel are both subject to central and state taxes, but the specific rates may vary. For example, in India, ATF attracts an 11% central excise duty, while VAT rates can range from 0% to 30% in different states. Even at the highest possible price, the tax on ATF is significantly lower than that of petrol and diesel.
Additionally, it is worth noting that jet fuel and automobile fuel have different compositions and properties. Jet fuel, often referred to as Jet-A, Jet-A1, or JP-8, is similar to kerosene or diesel and has a lower octane rating than regular unleaded automobile fuel. It is designed to withstand the unique operating temperatures and requirements of jet engines.
