Airports are hubs of transportation, facilitating travel for millions of passengers each year. With such a vast scale of operations, it is no surprise that airports consume significant amounts of fuel to keep their aircraft running. This fuel consumption varies across airports, depending on factors such as the number of flights, passenger traffic, and aircraft types. For instance, Narita Airport in Tokyo, Japan, reportedly transported 130 billion liters of fuel over 30 years, averaging 36.3 million barrels annually. Airports like Atlanta, known for its high domestic passenger traffic, and LAX and JFK, with substantial long-haul traffic, also contribute to the fuel consumption equation. Understanding fuel usage is crucial for airport operations, environmental considerations, and the economics of the aviation industry.

Fuel efficiency: long-haul flights are more fuel-efficient
Fuel efficiency is a key criterion in determining the economics of short and long-haul flights. Long-haul flights are more fuel-efficient than short-haul flights. This is due to several factors. Firstly, long-haul flights typically climb to a higher cruising altitude, which results in lower air density and reduced aerodynamic drag. On the other hand, short-haul flights operate at lower altitudes, leading to higher drag and increased fuel consumption.
Additionally, long-haul flights spend a smaller proportion of their total flight time at high-drag conditions during climb and descent. During a typical long-haul flight, the aircraft climbs for about 30 minutes and descends for another 30 minutes, amounting to 15% of the total flight time at high-drag conditions. The remaining 85% of the flight time is spent at a level flight or cruise phase, where drag is significantly lower.
The number of flight cycles, defined as a pair of one take-off and one landing, also impacts fuel efficiency. Short-haul flights experience a higher number of cycles, resulting in frequent pressurization and depressurization of the cabin. This places higher stresses on the airframe, leading to increased maintenance requirements and reduced fuel efficiency.
Furthermore, engine efficiency plays a role in the fuel efficiency of long-haul flights. During short-haul flights, engines heat up and cool down more frequently, causing greater wear and tear on temperature-sensitive parts. This results in the need for more frequent replacements of certain life-limited parts, which can impact overall fuel efficiency.
To optimize fuel efficiency, long-haul flights employ various strategies. One approach is to carry only the required amount of fuel, as fuel itself is heavy and reducing weight improves efficiency. Composite structural designs are also used, which are strong, lightweight, and efficient, enabling longer flights with lower fuel consumption. Another technique is Continuous Descent Approach (CDA), where aircraft descend with minimum engine thrust, gliding down to the runway to conserve fuel.

Jet fuel prices: state-owned oil companies can increase prices
The aviation industry is extremely sensitive to price changes, and jet fuel prices play a significant role in airline operations. Brazil's state-owned oil and gas company, Petrobras, implemented a 7% increase in jet fuel prices, effective January 1, 2025. This price adjustment was a response to market conditions, addressing rising oil costs and volatile global oil prices. The decision to raise jet fuel prices is part of Petrobras's strategy to align with global market dynamics, including exchange rate fluctuations.
Petrobras, as a major player in Brazil's energy sector, regularly revises its fuel prices to maintain profitability and ensure the continued operation of the country's energy market. The company considers crucial factors such as global oil price trends, exchange rates, and operational costs. The price increase will primarily impact fuel distributors who purchase jet fuel from Petrobras and supply it to Brazil's airlines.
While consumers may not immediately feel the effects of the price change, airlines will likely pass the increased fuel costs onto passengers, particularly on domestic flights, leading to higher ticket prices. This could further strain the aviation industry, which is still recovering from the COVID-19 pandemic's impact. Smaller carriers are more sensitive to rising costs and may struggle with the financial challenges posed by higher fuel prices.
The jet fuel price increase has broader implications beyond the aviation industry. Airlines often pass on fuel price increases to logistics providers, potentially driving up air freight costs. Consequently, consumer goods prices may rise, affecting shoppers across the country. As jet fuel prices fluctuate, state-owned oil companies play a pivotal role in navigating market dynamics and ensuring the sustainability of the aviation and broader energy sectors.

Fuel delivery: large amounts of fuel are transported to airports
Aviation fuel is delivered to airports in large quantities via various methods, including pipelines, tankers, barges, and trucks. Some major airports are connected to refineries by pipelines, such as the 5,500-mile-long Colonial Pipeline, which delivers gasoline, avgas, and jet fuel. Airports like Dulles International Airport source their fuel directly from these pipelines.
Other airports, such as Bristol Airport, receive their fuel by road tanker. A semi-sized tanker can hold about 10,000 gallons of fuel, and it is estimated that Bristol Airport requires approximately 320,000 litres of fuel daily, which equates to around eight tanker trucks per day. For lower-volume sites, it may be more cost-effective to transport fuel by truck rather than pipeline.
Additionally, coastal airports have the option of receiving fuel deliveries by barge, and some airports may have a combination of delivery methods. Airports typically have large tank farms nearby to store the significant quantities of fuel required to meet the demands of air traffic.

Fuel consumption: the US has the largest aircraft fleets
Fuel consumption in aircraft is a measure of the transport energy efficiency of an aircraft. The amount of fuel consumed by an aircraft depends on several factors, including the number of passengers, the distance travelled, the aircraft's speed, and the aircraft's fuel efficiency.
The fuel efficiency of an aircraft can be improved by optimising its aerodynamics, reducing its weight, and improving its engine brake-specific fuel consumption and propulsive efficiency or thrust-specific fuel consumption. For instance, the Airbus A380, which can carry over 800 passengers, burns 4,600 gallons of fuel per hour, while the older Boeing 747, which carries 568 passengers, burns 5 gallons of fuel per mile. Newer aircraft like the Boeing 787 Dreamliner, Airbus A350, and Bombardier CSeries are 20% more fuel-efficient per passenger kilometre than previous-generation aircraft.
The fuel economy of an aircraft also depends on its operating speed. Research has shown that designing aircraft for subsonic instead of transonic speed with turboprop instead of turbofan propulsion can save up to 21% of fuel compared to conventional aircraft designs.
The United States has the largest aircraft fleet in the world. While data on fuel consumption by country is limited, it can be inferred that the US likely consumes a significant amount of aircraft fuel due to its large aircraft fleet and high volume of air traffic. The global fuel consumption by commercial airlines reached an all-time high of 95 billion gallons in 2019, with a forecast of 99 billion gallons in 2024.

Fuel costs: fuel costs can be up to 50% of an airline's costs
Fuel costs can account for up to 50% of an airline's costs. This is a significant expense, and it is no surprise that fluctuations in fuel prices can have a large impact on an airline's balance sheet.
The amount of fuel used by an airport depends on many factors, including the number of flights, the type of aircraft, and the distance travelled. For example, a Boeing 747 uses approximately 1 gallon (about 4 litres) of fuel every 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 even more fuel-efficient, burning an average of 4,600 gallons (11,400 litres) of fuel per hour.
The cost of jet fuel also varies by region. For instance, in 2020, the price of jet fuel in Delhi, India, was ₹39.06 a litre, impacting the operating costs of Indian carriers. Airports with high fuel consumption include Narita in Tokyo, which transported 130 billion litres of jet fuel in its first 30 years of operation, and LAX and JFK, which have a high volume of long-haul traffic.
To reduce fuel costs, airlines have been incentivized to decrease fuel consumption. This can be achieved through more fuel-efficient aircraft, such as the Airbus A380, or by taking advantage of the jet stream on long-haul flights, which can increase fuel efficiency.
