Indian oil marketing companies announced aviation turbine fuel prices for April 2026 early on Wednesday morning, delivering the single largest monthly fuel price shock in the history of Indian commercial aviation. ATF for domestic flights has increased by approximately 115 percent compared to last month, crossing the Rs 2 lakh per kilolitre mark for the first time ever in Delhi, Kolkata, and Chennai. The price hike is a direct consequence of the Iran war’s impact on global crude oil markets and comes at a moment when Indian airlines are already operating under severe financial stress from rising fuel costs, a rupee at record lows, and longer flight routes due to West Asian airspace disruptions.
The Numbers
At Delhi’s Indira Gandhi International Airport, India’s busiest aviation hub, a kilolitre of ATF for domestic flights will now cost Rs 2,07,341.22 in April, up 114.5 percent from Rs 96,638.14 last month. This is the first time in history that domestic ATF pricing has crossed the Rs 2 lakh mark at Delhi.
At Mumbai’s Chhatrapati Shivaji Maharaj International Airport, India’s second busiest hub, the price has risen 115 percent from Rs 90,451.87 last month to Rs 1,94,968.67 in April.
For international flights, ATF pricing has crossed the $1,000 per kilolitre mark for the first time in India. A kilolitre of ATF for international flights will now cost $1,690.81 in Delhi, up 107 percent from $816.91 last month. Kolkata will see the highest international ATF price at $1,727.30 per kilolitre, up 102 percent from $855.25 last month.
A senior airline official noted that the IOC website prices announced Wednesday morning are for non-scheduled, adhoc, and charter operations and that prices for scheduled domestic carriers will be announced separately. The final pricing for IndiGo, Air India, Akasa, and other scheduled operators may differ but is expected to reflect the same broad magnitude of increase.
What This Means for Indian Airlines
Jet fuel accounts for 40 to 45 percent of airlines’ total operating costs under normal conditions. A 115 percent increase in the price of that input does not translate into a 115 percent increase in total operating costs, but it produces an increase in the fuel cost component that is so large it fundamentally changes the economics of operating individual routes, particularly thinner domestic routes where yields are low and margins are razor-thin.
The rupee’s position at record lows compounds the impact significantly. Most of airlines’ costs are dollar-denominated, including aircraft leases, maintenance contracts, spare parts, and international fuel purchases. With the rupee at approximately 95 per dollar and weakening further, every dollar-denominated cost is already more expensive in rupee terms than it was a month ago. The combination of higher ATF prices and a weaker rupee is hitting airlines from both directions simultaneously.
Air India CEO Campbell Wilson had warned employees last month that the financial impact of the Iran war crisis is yet to be fully felt and that most of the impact would only hit from April. He said escalating operating costs may force more airlines to cut flights depending on how fuel costs, airfares, and customer demand moves. Wednesday’s pricing announcement confirms that the impact has now arrived.
Wilson also noted the demand side constraint that limits airlines’ ability to simply pass costs through to passengers: “Not every customer is willing to pay higher airfares so there is a limit to how high we can price before demand drops. Additionally, given economic uncertainties, it is not certain that customers or companies will be as willing to travel as they were prior to the conflict, and may choose to stay put for a while.”
What Happens to Flight Tickets
Airlines will hike fares to reflect the increased operating costs. IndiGo, Air India group, and Akasa had already imposed or hiked fuel surcharges last month ranging from Rs 150 to $200. Those surcharges are now expected to be revised upward further in response to the April pricing.
The domestic fare cap of Rs 18,000 was removed on March 21, 2026, meaning airlines now have no regulatory ceiling on what they can charge passengers. Since airlines have received no fiscal relief on ATF excise duty from the central government or VAT relief from state governments including Delhi and Mumbai, they have made clear they will only support fare caps if their input costs are similarly capped.
Routes are now being evaluated individually. Airlines are watching each route closely to determine whether operating it makes economic sense at current fuel prices and anticipated demand levels. Routes with thin passenger volumes and limited pricing power are the most vulnerable to suspension or frequency reduction. Travellers on less popular domestic routes should expect reduced options and significantly higher fares in the weeks ahead.
The Historical Context
In April and May 2024, ATF for international flights was above $900 per kilolitre. At that time the dollar-rupee exchange rate was at 83 to 84 levels. Today ATF is at $1,690 per kilolitre and the rupee is at 95 per dollar. The combined impact of higher dollar pricing and a weaker rupee makes the current situation substantially more severe than any previous ATF price cycle in Indian aviation history.
Before the Iran war began on February 28, 2026, Indian ATF prices were already among the most expensive globally due to the domestic tax structure on aviation fuel. The 115 percent increase announced for April takes an already expensive input and doubles it, at the worst possible moment for an industry that had only recently returned to sustainable profitability after the COVID-19 pandemic years.
For passengers, for airlines, and for India’s aviation sector more broadly, April 2026 marks the arrival of the fuel cost shock that Air India’s CEO warned was coming. It has arrived in full.
