Jet Airways made a profit in the June quarter compared to a loss in the year-ago period, helped by a drop in fuel expenses and a one-time gain on sale and leaseback of engines.
The Mumbai-based and India's second largest carrier by market share, said net profit in the April-June quarter was at Rs 221 crore ($33.80 million), compared with a loss of Rs 218 crore the same quarter last year.
Despite rapidly rising demand for air travel in India, Jet has not made an annual profit since 2007, dragged into the red by high operating costs and fierce competition for passenger fares.
A drop in fuel prices has, however, eased the squeeze on Indian airlines this year - low-cost rival SpiceJet swung to a small net profit in the last quarter - but analysts say ticket prices are still too low and costs too high for sustained profitability.
Jet, 24% owned by Abu Dhabi's Etihad, last year announced a cost-cutting plan and said it expected to make a full-year profit in 2017.
