(Reuters) - India's IndiGo airline operator Interglobe Aviation swung to its first quarterly loss in two years, weighed down by fuel expenses and aircraft rental costs.

The country's biggest airline by market share said on Friday it made a loss of 9.89 billion rupees ($117.7 million) for the three months to Sept. 30 compared to a profit of 1.88 billion rupees a year ago.
