The airline had on Monday announced the commencement of its operations under the government's regional connectivity scheme, Udan, from June 14 onwards, with the first flight to be operated on the Lucknow-Allahabad-Patna sector.
Jet Airways had bagged four routes in the second round of bidding in January, in which a total of 325 routes were awarded to various operators.
The fare for a Delhi-Nashik-Delhi flight will be Rs 2,665, it said.
With at least half of the seats in the Udan flights are offered at subsidised rates, the participating carriers get a certain amount of viability gap funding (VGF) - an amount shared between the Centre and the states concerned.
The government had in March 2017 awarded 128 regional routes to five airlines for launching flights under the Udan (Ude Desh Ka Aam Naagrik) scheme, which aims at boosting air connectivity to the hinterland.
Under the scheme, the fares have been kept at Rs 2,500 for a one-hour journey.
