Aviation Turbine Fuel, or ATF, price at Delhi was cut by Rs 3,025.34 per kilolitre, or 4 per cent, to Rs 71,800.21 per kl, according to Indian Oil Corp, the nation's largest fuel retailer.
The rate cut follows a Rs 753.34 per kl hike in rates last month.
Price was cut as international oil prices fell and rupee appreciated against the US dollar, making imports cheaper.
In Mumbai, jet fuel costs Rs 74,105.16 per kl as against Rs 77,322.6 per kl previously, IOC said. Rates at different airports vary because of difference in local sales tax or VAT.
Jet fuel constitutes over 40 per cent of an airline's operating costs and the price cut will reduce the fuel cost of the cash-strapped carriers.
No immediate comments were available from the airlines on the impact of the price cut on passenger fares.
