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.

No immediate comments were available from the airlines on the impact of the price cut on passenger fares.
Separately, the price of non-subsidised cooking gas (LPG), which customers buy after using up their quota of 12 subsidised cylinders, was cut by Rs 100 per cylinder, the third straight reduction in rates since February.
The 14.2-kg cooking gas cylinder that consumers buy beyond their entitled 12 bottles at subsidised rates, will now cost Rs 980.50, down from Rs 1,080.50, in Delhi.
The rates were on February 1 cut by Rs 107 -- from Rs 1,241 per cylinder to Rs 1,134, and then by Rs 53.5 per cylinder last month.
