Higher oil prices do not automatically translate into more expensive airline tickets. New research from the University of Adelaide shows that airfare is shaped by a complex mix of fuel costs, demand dynamics, and airline risk-management strategies.
The complex relationship between airline ticket prices and fuel costs
When oil prices rise, airline tickets inevitably become more expensive. Or do they?
A study by the University of Adelaide, published in the journal Research in Transportation Economics, challenges the conventional link between jet fuel costs and airfares. The research highlights the crucial role played by the source of market shocks and by airlines’ risk-management strategies.
For aviation analysts and transportation economists, the reality is far more nuanced than the common assumption that higher fuel prices automatically lead to higher ticket prices.

How much fuel costs matter to airlines
According to the Australian study, aviation fuel accounts for between 25% and 40% of an airline’s total operating expenses.
Yet the research also shows that the relationship between fuel costs and ticket prices is far from straightforward. Focusing on the Australian market, where roughly 90% of jet fuel is imported, researchers analyzed data from the Australian Bureau of Infrastructure and Transport Research Economics and divided fares into three categories:
- Business
- Economy
- Discount
The study’s main finding is that the cause of a fuel price shock matters far more than the price increase itself.
Why airlines are resilient to supply shocks
Contrary to expectations, disruptions linked to wars, natural disasters, or supply chain interruptions have a relatively limited direct impact on domestic airfares.
Airlines often soften these shocks through sophisticated operational strategies, including fuel hedging programs, long-term supply contracts, and flexible fleet and capacity management.
In practical terms, travelers do not immediately feel the effects of geopolitical instability because carriers have mechanisms in place to absorb part of the increase in fuel costs.
When economic growth drives fares higher
The situation changes when fuel prices rise because of strong economic growth.
In a favorable macroeconomic environment, demand for travel, especially business travel, increases. Airlines gain greater pricing power and can raise fares without significantly reducing passenger volumes.
As a result, demand-driven fuel price increases tend to have a much stronger impact on both business-class and economy-class ticket prices than supply-related disruptions.
The impact of precautionary oil stockpiling
Another scenario occurs when market participants begin stockpiling oil due to fears of future shortages, geopolitical risks, or climate-related disruptions.
According to the researchers, these shocks can create unusual pricing dynamics. Business-class fares may decline in the short term as companies reduce travel budgets amid uncertainty. At the same time, discount fares may increase as consumers rush toward lower-cost travel options.
This divergence highlights how airfare pricing depends not only on operating costs but also on changing consumer and corporate behavior.
What it means for sustainable aviation fuel
Understanding how airfares respond to cost fluctuations is becoming increasingly important as governments and regulators design policies to accelerate the adoption of sustainable aviation fuel (SAF) and carbon pricing mechanisms.
If airlines can successfully absorb supply-side fuel shocks through hedging and other financial tools, the transition toward cleaner but more expensive fuels may require more flexible pricing strategies.
The challenge for the aviation sector will be balancing decarbonization goals with affordability, ensuring that the additional costs associated with SAF adoption do not fall entirely on passengers while still supporting the industry’s long-term sustainability objectives.
