Why Air Fares Are Soaring: Conflict, Fuel Prices and Supply Constraints Explained

Air fares have surged sharply over the past year, with the cheapest economy tickets now costing 24% more on average, according to new research. Behind this rise lies a combination of global conflict, rising costs, and reduced supply — making it a clear real-world example of how supply and demand interact in markets.

The ongoing conflict in the Middle East has disrupted key air routes, forcing airlines to take longer journeys to avoid restricted airspace. This increases fuel usage, raising airlines’ costs of production. At the same time, oil supply disruptions have pushed jet fuel prices from around $85–$90 per barrel to as high as $150–$200, significantly increasing operating costs. Since fuel accounts for up to 25% of airline expenses, this has a major impact on pricing decisions.

From an economic perspective, this represents a leftward shift of the supply curve. Higher costs mean airlines are willing and able to supply fewer flights at each price level, leading to higher equilibrium prices. This is why ticket prices have risen so sharply, particularly on long-haul routes.

At the same time, supply has been further reduced by the disruption of major Gulf airlines, which normally provide a large share of long-distance flights. With fewer planes operating, there are fewer seats available, pushing prices even higher. For example, flights from London to Melbourne are now 76% more expensive, while Hong Kong to London routes have risen by 72%.

While some rival airlines have tried to increase capacity, they have not fully replaced the lost supply. This shows how markets do not always adjust instantly, especially when there are barriers such as infrastructure limits, airport slots, and regulatory constraints.

Airlines are now calling on governments to step in. Proposed measures include cutting taxes like Air Passenger Duty, relaxing regulations, and even prioritising jet fuel production. These responses highlight the role of government intervention in stabilising markets during external shocks.

For economics students, this situation clearly demonstrates how external factors such as geopolitical conflict can shift supply, leading to higher prices, reduced availability, and calls for government action. It also raises important questions about how markets respond to shocks and whether intervention is always the best solution.
