IndiGo says it will raise fuel charges for both domestic and international flights, making some tickets costlier. NDTV reports the company will revise these charges from October 6, citing an increase in aviation turbine fuel (ATF) prices.

Several outlets link the change to higher ATF costs. NDTV describes the ATF price rise as about 14%, while Skift notes this is the third fuel-charge increase by IndiGo this year. Skift also characterizes the broader pressure on India’s low-fare airline model as operating costs rise, noting that the latest adjustment is smaller than an earlier increase in April.

While the details differ by outlet—such as the emphasis on the size of the latest hike versus the number of times charges have been adjusted—each account attributes the surcharge revision to surging ATF expenses affecting ticket pricing.
