It is also understood the airline, which has struggled financially in recent months, will not pursue a second daily Heathrow-Delhi flight at this time.
The confirmation comes after Jet Airways suspended its Manchester-Mumbai route until the end of April last month amid its worsening financial position.
Chairman and founder Naresh Goyal has since stepped aside to allow fresh investment in the carrier he set up in the early 1990s.
A spokesperson for Jet Airways confirmed to TTG it would operate two flights a day between Heathrow and Mumbai and one between Heathrow and Delhi during summer 2019, effective from March 31.
The airline declined to comment on the situation around Jet Airways’ Manchester-Mumbai service.
Goyal’s resignation as chairman last week opened the door for a consortium led by State Bank of India to take a majority shareholding.
Jet Airways’ new backers have pledged to pump INR 1,500 crore (£162 million) into the airline in the interim, allowing it to re-deploy a number of grounded aircraft.
