Almost all Indian airlines, barring Jet Airways, IndiGo and GoAir, suffered losses in 2012-13 with Air India suffering the highest loss of ₹5,490 crore, the Lok Sabha was informed on Monday.

While SpiceJet registered a loss of ₹2,798.2 crore in 2012-13, Jet’s low-cost subsidiary JetLite recorded a loss of ₹2,468 crore, Minister of State for Civil Aviation GM Siddeshwara said in reply to a question.

Low-cost airline IndiGo earned a profit of ₹7,958 crore and GoAir recorded a profit of ₹851 crore, he said.

A major reason for the losses was the changing air transport environment dictated by the global economic scenario, forcing airlines to seek structural adjustments in order to survive, Siddeshwara said.
