New Delhi, Oct. 6 -- India's largest airline, IndiGo, on Monday revised its fuel surcharge for all domestic and international flights applicable for bookings made from Tuesday, which will push airfares further. According to a statement by the airline, it has "marginally recalibrated" its fuel charges in the wake of volatile air-turbine fuel (ATF) prices in recent months, especially following geopolitical issues in the West Asia. "In view of the situation, IndiGo has marginally re-calibrated its fuel charges across its domestic as well as international flights. The following charges will be included in all new bookings on IndiGo flights starting 0001 hrs on 06 October 2026," the airline said. "The continuous rise in the fuel prices, with the latest month-on-month increase exceeding 14%,has taken ATF costs to levels that are amongst the highest in the last decade," it added. The quantum of the hike ranges from Rs.100 to Rs.350 for domestic flights depending on distance. Under the revised structure, fuel charges on domestic routes have been increased to Rs.375 for flights up to 500 km, Rs.600 for flights upto 1000km, Rs.900 for flying between 1001 to 1500km, Rs.1,150 for flights operating for a distance upto 2,000 km and Rs.1,300 for flights beyond 2,000 km. For international flights, the charges are fixed at Rs.1,000 for SAARC routes up to 500 km and Rs.3,000 for those beyond 500 km. Flights to Southeast Asia, the Gulf and Middle East countries and North and East Asia will have a charge of Rs.5,500. The fuel charge for Africa will be Rs.6,000 and Rs.10,000 for Europe. The airline said that, as ATF charge is a significant share of airline's operating costs, this rise is expected to impact airlines' cost structures and network economics, including those of IndiGo....
