In an interview with ET's chief executive officer Pieter Elbers, IndiGo's size should be compared with global carriers and not other domestic airlines, as such benchmarking will help India transform its airports into airport hubs, Elbers said.
Elbers' tending to scrutinise domestic competition, assess fares on domestic routes, and determine whether they are high.
India's international passenger market is dominated by foreign airlines.
In response to SpiceJet's financial difficulties, Go First's insolvency proceedings, and Akasa Air reducing flights due to a pilot shortage, the domestic passenger market in India is now dominated by two airlines: IndiGo and Air India. Together, they account for approximately 85 percent of the market, with IndiGo holding a 60 percent share on its own. The high airfares have caused concerns about the airline's quality.
Tata Group's acquisition of Air India is a natural advancement in a maturing market, he said. In other parts of the world, expansion has been observed as the aerospace market matures.
