NEW DELHI / BENGALURU, May 27 (Reuters) – Interglobe Aviation, owner of the Indian airline IndiGo, said Monday a good year after the bankruptcy of Jet Airways Ltd, which allowed the company to declare its profit fivefold for the fourth quarter.

IndiGo, the country's largest airline in terms of market share, has been gaining pbadengers in recent months due to funding difficulties with Jet Airways Ltd, which began anchoring its fleet earlier this year. Jet was finally forced to stop all operations.

"For the future, it's hard not to be optimistic for the future," said Executive Director Ronojoy Dutta in a statement.

At a post-profit call, Dutta said the Jet closure increased revenues per available seat-kilometer by 3% to 4%. This figure, which measures the carrier's operating profit, increased by 5.9% to 3.63 rupees in January-March. The number of available seat kilometers, which measures the airline's pbadenger capacity, is expected to increase by 30% in the current year.

High fuel prices, weak rupee and intense competition weighed on profitability in the first half of the year, Dutta said, adding that there was "a sharp recovery" in the second half of the year. .

Jet's problems have allowed IndiGo and other carriers such as SpiceJet to raise prices on some routes.

The pbadenger yield of IndiGo, a measure of air fare, increased by 12% during the quarter.

"The main positive element here is the increase in yield, which is largely due to Jet Airways," said Paarth Gala, aviation badyst at Prabhudas Lilladher.

"The yield will be firm in the future."

CEO Dutta said Jet's grounding helped IndiGo raise rates, but ticket prices would go down in June.

Earnings for the quarter indicated reached Rs. 5.90 billion ($ 84.87 million) for the quarter ended March 31, compared with Rs.1.18 billion a year earlier.

The company's shares closed at record highs, up 2.5% in a larger market in Mumbai, up 0.7%.
