IndiGo, one of India's leading airlines, has announced an increase in airfare prices due to a 25% hike in aviation turbine fuel (ATF) costs mandated by the Indian government. The new fuel charges will vary based on distance, with the lowest charge set at ₹275 for flights under 500 kilometers and reaching ₹950 for flights over 2,000 kilometers. For international flights to the UK and Europe, the revised fuel charge will be as high as ₹10,000. This decision comes after the Ministry of Petroleum confirmed the ATF price increase, which is aimed at mitigating the impact of rising international fuel costs on domestic travel. Fuel expenses constitute about 40% of an airline's operating costs, making this adjustment significant for both the airline and its passengers. The new fare structure will be effective for bookings made after 1 am on Thursday, with all domestic bookings from April 2, 2026 reflecting the updated fuel charges.
