Aviation Turbine Fuel (ATF)
"The specialised kerosene-based fuel used in aircraft turbine engines, whose pricing directly impacts airline operating costs and ticket prices"
Aviation Turbine Fuel (ATF), also known as Jet-A1 fuel internationally, is a specialised kerosene-type fuel designed for gas turbine engines in commercial and military aircraft. ATF constitutes approximately 35-40% of an airline's total operating costs in India, making it the single largest cost component. ATF pricing in India is revised fortnightly by state-owned oil marketing companies (IOCL, BPCL, HPCL) based on international crude oil prices, exchange rates, and refinery costs. Unlike petrol and diesel, ATF is subject to VAT by state governments (not excise duty), with rates varying from 1% to 30% across states — creating wide price differentials. The Government of India has been promoting Sustainable Aviation Fuel (SAF) as an alternative to conventional ATF to reduce aviation sector carbon emissions.
Important for UPSC GS-3 (Infrastructure — Aviation sector, Energy) and Prelims. UPSC tests the cost structure of airlines, the tax regime on aviation fuel (VAT not excise), and the impact of crude oil price fluctuations on air connectivity. The concept connects to UDAN, Sustainable Aviation Fuel, and energy security.
- 1 Kerosene-based fuel for aircraft turbine engines (also called Jet-A1)
- 2 Constitutes 35-40% of airline operating costs in India
- 3 Priced fortnightly by OMCs based on international crude and exchange rates
- 4 Subject to state VAT (not central excise) — rates vary 1-30% across states
- 5 India promoting Sustainable Aviation Fuel (SAF) as lower-carbon alternative
With Brent crude surging past $106/barrel due to the Strait of Hormuz crisis in March 2026, ATF prices in India rose sharply — directly impacting airline costs and threatening the affordability gains achieved under the UDAN regional connectivity scheme.
