IndiGo lifts domestic fuel charges to between Rs 375 and Rs 1,300 from 6 October

IndiGo will raise its fuel charge on domestic and international tickets from 6 October, after aviation turbine fuel rose more than 14 percent in a month. The airline said the latest price takes ATF to among the highest levels of the past decade. Domestic charges, which had run from Rs 275 to Rs 950 by distance, will run from Rs 375 to Rs 1,300. That is an increase of Rs 100 to Rs 350. International charges move from a band of Rs 900 to Rs 10,000 to a band of Rs 1,000 to Rs 10,000.

The carrier last raised the charge in April. It pointed to price swings tied to the US-Israel-Iran war. Jet fuel, IndiGo said, makes up a significant share of an airline's operating costs. Khaleej Times put that share at up to 40 percent. A 14 percent monthly jump in the largest single cost shows up in fares within days, because Indian carriers pass ATF through a published surcharge rather than hiding all of it in the base fare.

The loss already on the books

IndiGo posted a first-quarter loss of Rs 3.82 billion. In May the company said it would consider hedging fuel to protect margins. Monday's notice is the unhedged response: a higher charge, effective Tuesday, scaled by distance. A passenger on a short domestic sector pays Rs 100 more than the old floor. A passenger on a long domestic sector pays Rs 350 more than the old ceiling. On international routes the floor rises by Rs 100 and the ceiling stays at Rs 10,000, so the long-haul charge is unchanged at the top and only the shorter international bands move.

That shape matters for the network. The domestic ceiling rising from Rs 950 to Rs 1,300 is a 37 percent increase at the top of the old band. The international ceiling does not move. IndiGo is loading more of the ATF jump onto domestic distance than onto the longest international tickets, which were already at the Rs 10,000 cap.

What sits behind the ATF print

The G7 agreed on Friday to release 100 million barrels over four months, with diesel brought forward in the first 20 days. That release is aimed at product tightness linked to the same Middle East disruption IndiGo cited. It will not change Tuesday's surcharge. Indian ATF is priced off import parity, and a stock release reaches that formula only after cargoes and refinery runs adjust. The airline's own number is the one on the ticket: 14 percent month on month, and a charge card that now starts at Rs 375.

Mumbai airport has separately told airlines it plans to drop 265 international flights from Terminal 2 from 26 October. IndiGo's fuel notice is a cost decision, not a schedule decision. The two land in the same month. A passenger flying IndiGo after 6 October pays the new charge. A passenger booked on one of the Mumbai international flights still under review may also lose the sector. The fuel line is the one the airline has already fixed.

How the bands land on a ticket

The old domestic band started at Rs 275 and ended at Rs 950. The new one starts at Rs 375 and ends at Rs 1,300. On the shortest sectors the increase is Rs 100. On the longest it is Rs 350. A family of four on a long domestic flight pays Rs 1,400 more in fuel charge than it would have paid on Sunday. That is the number the 14 percent ATF print becomes at the gate. Internationally, the ceiling stays at Rs 10,000, so the longest tickets do not take a further hit at the top of the card.

IndiGo's May comment on hedging is the unfinished part. A surcharge moves the cost to the passenger after the fuel has already been bought. A hedge would have moved it earlier, at a premium. The airline has not said, in Monday's notice, that a hedge is now in place. The notice says the charge has been recalibrated. Recalibrated, in this tariff, means the distance bands above.
