NAIROBI, Kenya — Travellers in Kenya could soon face higher air ticket prices after the Energy and Petroleum Regulatory Authority (EPRA) increased kerosene prices in its latest monthly fuel review, a move that is expected to ripple into aviation costs.
The revision comes amid ongoing pressure from the transport sector, including a recent Matatu strike that disrupted public transport for two days.
While kerosene is commonly associated with household use, industry experts note that its pricing has a direct link to aviation fuel costs.
Link between kerosene and aviation fuel
Commercial aircraft do not run on petrol or diesel. Instead, they use Jet A-1 fuel, a highly refined form of kerosene.
This means fluctuations in kerosene prices often feed directly into airline operating costs, influencing overall fare structures.
Jet fuel has been the backbone of modern aviation for decades due to its stability, energy efficiency, and safety performance under extreme conditions.
Why is jet fuel kerosene-based
Jet fuel evolved from kerosene in the early 20th century after proving more reliable than petrol for aviation use. Today, it remains the global standard for commercial aircraft.
At cruising altitudes of about 35,000 feet, temperatures can fall to nearly minus 50°C. Jet fuel is engineered to remain usable at freezing points of around -47°C, preventing it from solidifying mid-flight.
It also has a high flash point, reducing the risk of accidental ignition during storage and refuelling operations at airports.
Unlike petrol, kerosene burns in a controlled and steady manner, which is critical for jet engines that require consistent thrust and stable combustion.
High efficiency and strict standards
Jet A-1 fuel is designed to maintain smooth flow even in extreme cold conditions at high altitude. This ensures uninterrupted circulation through aircraft engine systems.
It also carries a high energy density relative to its weight, allowing aircraft to travel long distances without excessive fuel load that would affect performance and efficiency.
The fuel is tightly regulated under international aviation standards, with strict requirements on freezing point, flash point, and chemical composition. Additives are also used to prevent icing and corrosion in engine systems.
Impact on airline operations
Because fuel is one of the highest operating costs for airlines, even small increases in input prices can significantly affect overall expenses.
Airlines often respond to such changes by adjusting ticket prices, particularly on routes with already thin profit margins.
