IndiGo has announced an increase in fuel surcharges on its domestic and international flights, citing a sharp rise in aviation turbine fuel (ATF) prices. The revised charges will come into effect from October 6 and are expected to push up airfares for passengers.
The airline said the fuel surcharge on domestic flights will increase by Rs 100 to Rs 350, depending on the distance of the journey. A revised fuel charge will also be applicable to international flights, although the airline did not provide a detailed breakup of the increase for those routes.
IndiGo, India’s largest airline by domestic market share, said the decision was prompted by the continued increase in jet fuel prices. According to the airline, ATF prices have risen by more than 14 per cent month-on-month, taking fuel costs to among their highest levels in the past decade.
The airline said the increase in fuel prices was having a direct impact on its operating expenses because aviation turbine fuel accounts for a significant portion of an airline’s overall costs.
“Given that Aviation Turbine Fuel (ATF) makes up a significant share of airlines’ operating costs, this rise is expected to impact airlines’ cost structures and network economics, including those of IndiGo,” the airline said in a statement.
In response to the higher fuel costs, IndiGo said it had marginally recalibrated its fuel charges across both domestic and international services.
The surcharge will be added to the applicable fare, meaning passengers booking flights from October 6 could see higher overall ticket prices. The actual increase in the total fare will depend on factors including the route, distance and applicable taxes and charges.
Fuel prices are a major component of airline operating costs and changes in ATF rates can have a significant impact on the economics of air travel. Airlines typically adjust fares or introduce fuel surcharges when sustained increases in fuel costs put pressure on their margins.
For domestic travellers, the announced increase of Rs 100 to Rs 350 means the impact will vary according to the length of the journey. Shorter flights will attract a lower surcharge, while passengers travelling on longer domestic routes will face the higher end of the revised charge.
The airline’s move comes amid elevated fuel costs in the aviation sector. IndiGo said the latest month-on-month increase in fuel prices had pushed ATF rates to levels that rank among the highest seen over the past 10 years.
The revised fuel surcharge will apply from October 6 to eligible domestic and international flights. Passengers planning to travel after the effective date may therefore need to account for the additional charge while comparing ticket prices.
The airline has described the adjustment as a marginal recalibration of fuel charges in response to the changing cost environment. The move highlights the continuing sensitivity of airline fares to fluctuations in aviation fuel prices.
With ATF forming a substantial part of operating expenses, any sustained rise in fuel prices could continue to influence airline pricing and passenger travel costs in the coming months.
