IndiGo has increased its fuel surcharge on domestic and international flights, raising the cost of new bookings made from October 6 as aviation turbine fuel prices reach levels among the highest in the last decade. The surcharge increase ranges from Rs 100 to Rs 350 per sector on domestic routes and goes up to Rs 2,500 per sector on international flights.
The revised charges apply to bookings made after 12.01 am on October 6, 2026. The move comes ahead of the festive travel season, when demand for air travel typically becomes an important consideration for passengers planning domestic and overseas journeys.
IndiGo attributed the change to continuously rising aviation turbine fuel, or ATF, prices and mounting operating expenses. In a statement, the airline said the latest month-on-month increase in fuel prices had exceeded 14%, taking ATF costs to levels among the highest recorded in the last decade.
The airline said ATF prices had remained volatile in recent months, particularly because of geopolitical developments in the Middle East. The Times of India report linked the latest pressure on fuel costs to the continuing US-Iran conflict and a weakening rupee, both of which have added to uncertainty around airline operating expenses.
The surcharge will apply separately by sector, meaning that passengers travelling on itineraries involving multiple sectors could face a higher total increase than those taking a single flight. The exact impact on an individual booking will depend on whether the journey is domestic or international and on the number of sectors included in the itinerary.
IndiGo’s decision is the third fuel-surcharge increase since the West Asia crisis began, according to the report. Other airlines are likely to review their charges, although the report does not establish that any competing carrier has announced a matching increase.
ATF is one of the largest variable costs for airlines, making airfares sensitive to changes in fuel prices and currency conditions. The latest decision shows how external shocks can quickly reach passengers through ticket pricing, even when the immediate change is described as a surcharge rather than a revision to the base fare.
For travellers, the change means that bookings made from October 6 will carry an additional fuel-related component. Domestic passengers will see an increase of between Rs 100 and Rs 350 per sector, while international passengers could pay up to Rs 2,500 more per sector. IndiGo has not indicated in the supplied statement how long the revised surcharge will remain in force.
The airline’s next pricing decisions will depend on the movement of ATF costs and the operating conditions cited in its statement. Any further changes by IndiGo or other airlines will determine whether the latest increase remains limited to one carrier or becomes more widely reflected in airfares.
