Aviation Turbine Fuel (ATF) is why your last-minute Delhi–Leh or Delhi–Srinagar ticket in 2026 can cost almost as much as a short-haul international flight. India taxes ATF at higher rates than almost any other major aviation market, and when crude prices spike, airlines pass the increase to the passengers who have no choice but to fly — which means late bookers.
TL;DR — the short answer
Aviation Turbine Fuel (ATF) is the single biggest cost for Indian airlines, and India’s ATF is priced high because state governments levy VAT on top of central excise duty — unlike most major aviation markets where jet fuel is exempt from state taxes. When ATF prices rose sharply in early 2026, airlines adjusted upward through a combination of higher base fares and explicit fuel surcharges. Late bookers absorb the most because they’re buying into the last and most expensive fare buckets, where the surcharge-per-seat math is stacked against them. The so-called ‘government cap’ limits what airlines can charge on certain domestic routes, but it applies to the base fare structure, not to unrestricted last-minute seats. Verify the current ATF price (published monthly by BPCL, HPCL and IOC on their websites) and DGCA fare cap notifications on dgca.gov.in for the most current numbers.
What exactly is ATF and why does India pay so much for it?
Aviation Turbine Fuel is the kerosene-grade jet fuel that powers every commercial aircraft engine. Globally, it is priced as a derivative of crude oil — when Brent crude goes up, ATF goes up. But India has a specific problem: ATF is excluded from the Goods and Services Tax (GST) framework, which means it is still taxed under the old structure — central excise duty plus state VAT.
State VAT on ATF varies from state to state. Some states charge upward of 25–30% VAT on ATF; a handful of states (typically those trying to attract airline operations to their airports) have reduced it to 1–5%. Airlines buy fuel at whichever airports they refuel, and their cost basis is partly a function of where they tank up. An IndiGo flight from Delhi to Srinagar that refuels in Delhi pays Delhi’s ATF rate; if it can ferry a full tank, it might avoid refuelling in Srinagar at all.
The net result is that Indian airlines pay among the highest effective ATF taxes in the world. This is a long-standing industry complaint; IATA has repeatedly flagged India’s ATF taxation as a structural barrier to affordable aviation. The central government has periodically discussed bringing ATF under GST, which would likely reduce overall tax rates — but as of mid-2026, this has not happened. Verify the current policy status with the Ministry of Civil Aviation or IATA India.
What happened to ATF prices in early 2026?
I cover hill-station routes extensively — Delhi–Srinagar, Delhi–Leh, Delhi–Dehra Dun — and the price jump in early 2026 was jarring. ATF prices at major Indian airports rose meaningfully through Q1 2026, driven by a combination of crude price increases and rupee depreciation (India imports most of its crude oil, so a weaker rupee means higher ATF costs in rupee terms even if crude in dollar terms is flat).
Airlines responded with a mix of approaches: IndiGo raised its effective fuel surcharge component embedded in base fares; Air India added explicit fuel surcharges on international routes; both airlines reduced promotional fare availability. The fare buckets that seat-sale fares occupy were narrowed, so the ‘floor’ fare was higher than it was in 2025 on comparable routes.
For precise month-by-month ATF price data, check the fuel price notifications published by oil marketing companies — BPCL, HPCL, and IOC all publish ATF prices at major airports on their websites, updated monthly. This is the authoritative source; anything I write here is a historical snapshot.
How do airlines pass ATF costs to late bookers specifically?
This is the mechanism that makes last-minute seats disproportionately expensive, and it’s worth understanding in detail:
Airlines break their cabin into fare ‘buckets’ — let’s call them A through Z for simplicity. Bucket A is the cheapest promotional fare; bucket Z is the full unrestricted walk-up fare. Each bucket has a limited number of seats. When a new schedule opens (say, 90 days before departure), the airline puts a certain number of seats in bucket A, a few more in B, and so on up to Z.
As the flight fills and demand is confirmed, the algorithm closes cheaper buckets. By the time you’re buying 48 hours before departure, buckets A through, say, W are closed. You’re buying from X, Y or Z — the most expensive seats, which were priced to recover the airline’s full marginal cost including peak ATF, airport slot costs, crew overtime and a profit margin on what is essentially a captive buyer.
The fuel cost is embedded in the base fare across all buckets, but the absolute rupee amount per seat is highest in the top buckets because the airline built in a cost-recovery floor. On a Tier-2 short-haul flight where ATF represents a higher fraction of total seat cost (relative to a longer metro flight), this floor is proportionally higher. That’s why a last-minute 90-minute Bhopal flight can cost nearly as much as a 3-hour Delhi–Mumbai ticket booked in advance.
What does the government’s domestic fare cap actually do?
DGCA has periodically issued fare cap notifications for domestic routes — most notably the caps introduced during the COVID recovery period in 2020–21 and revisited briefly in later periods. These caps set a maximum fare per seat on specific route distance bands. They were genuinely designed to prevent price gouging during supply disruptions when airlines have outsized pricing power.
However, the caps as they’ve been structured apply to a band of fares, not to every seat on every flight. Unrestricted last-minute seats — those top fare buckets — may be subject to cap ceilings, but when demand is high enough that all remaining seats are in the top bucket, the cap may already be at or near the ceiling price. So the cap prevents the absolute worst extremes but doesn’t bring last-minute fares down to early-booking levels.
Whether a fare cap is currently active on any specific route band is something to verify on dgca.gov.in — these caps have been switched on and off based on market conditions and are not always active. I’d rather you check the source than trust a static number from this article.
What can you actually do to reduce what you pay?
If you know you’re likely to book last-minute (which is my life — mountain trips that come together on short notice), a few things help:
- Watch for ATF price cycles. ATF is revised monthly. If crude has dropped, next month’s fares may be slightly lower. Not a huge lever for a last-minute booking, but useful if you have even two weeks of flexibility.
- Buy miles now, burn them when you need to fly last-minute. Award redemptions on Air India’s Maharaja Club and IndiGo 6E Rewards are largely insulated from ATF-driven cash fare spikes. A domestic award from Maharaja Club can often be had for 1,500–3,500 miles last-minute when the cash fare is ₹10,000+. See our article on Maharaja Club last-minute redemptions.
- Use a travel card with high earn rates on flight bookings. If you’re paying ₹8,000–12,000 for a last-minute seat, make sure you’re earning points at the highest possible rate. Cards like Axis Magnus (TRAVEL EDGE portal) or HDFC Infinia earn significantly on travel bookings. See our Axis Magnus analysis.
- Book through the airline directly, not a third-party OTA. OTAs add a service fee (ranging from ₹200 to ₹600 per booking on average) on top of the fare. For a last-minute booking where the base fare is already high, this adds up. FlightGPT shows you the options; click through to the airline for the final purchase.
- Check if a train is faster than you think. For routes like Delhi–Chandigarh, Delhi–Agra, or Mumbai–Pune, a Shatabdi or Vande Bharat train may cost ₹500–800 and arrive not much later than the flight+airport time. Last-minute train tickets are also expensive, but generally less so than last-minute flights.
Bottom line
India’s ATF problem is structural and unlikely to be fully resolved without either bringing ATF under GST or lowering state VAT rates — neither of which is happening quickly. For travellers, the practical take is: buy in advance whenever you can, use miles for forced last-minute bookings, and use a high-earn travel card to claw back some value when you have to pay a big last-minute fare. If you’re planning hill-station trips that depend on road conditions and weather windows, building a stash of Maharaja Club or 6E Rewards miles in advance is genuinely worth the effort.

Frequently asked questions
What is ATF and why is it so expensive in India?
Aviation Turbine Fuel (ATF) is jet fuel. India taxes it heavily — central excise duty plus state VAT (which varies by state, sometimes 25–30%) — because it sits outside the GST framework. Most major aviation markets have lower or zero VAT on jet fuel. This structural tax burden makes Indian airlines’ fuel costs among the highest globally, which flows into ticket prices.
Does the DGCA fare cap prevent last-minute price spikes?
DGCA’s domestic fare caps (when active) set a ceiling per route distance band. They prevent the absolute worst extremes, but last-minute seats in the top fare bucket often hit or approach that ceiling on high-demand routes. Whether a cap is currently active is on dgca.gov.in — they’ve been switched on and off over the years.
What is a fuel surcharge and is it separate from the base fare?
Some airlines list a fuel surcharge (YQ in GDS terminology) as a separate line item; others embed it in the base fare. In India, domestic airlines often embed ATF recovery in the base fare rather than showing it separately, so you won’t always see a labelled ‘fuel surcharge’ on domestic bookings. On international bookings by Indian carriers, you may see YQ as a distinct charge. The net effect on your total ticket price is the same.
Why do last-minute flights on thin routes cost more than on metro routes?
On a metro route with 30+ departures per day and four competing airlines, late-booking demand is spread across many flights. On a Bhopal or Raipur route with two daily departures and one carrier, the same late-booking demand competes for far fewer seats. Revenue management software closes cheap buckets faster, pushing remaining seats into expensive fare classes.
Where can I check current ATF prices in India?
Oil marketing companies — BPCL, HPCL, and IOC — publish ATF prices at major Indian airports monthly on their official websites. IATA also tracks ATF differentials. These are the authoritative sources for current prices.
Is there a government subsidy or relief for passengers on high last-minute fares?
Not directly for passengers. The UDAN scheme subsidises airlines (not passengers directly) to operate routes to Tier-2/3 cities, with a capped fare on a limited number of seats per flight. Those seats are rarely available at the last minute. The broader ATF tax reduction under GST is a long-discussed policy reform that has not been implemented as of mid-2026.
