Why IndiGo, SpiceJet don't see threat from AirAsia

Even as AirAsia is all set to start an airline in India after clearing political hurdles, domestic carriers like Indigo and SpiceJet  do not see it as a threat to their existence.
For instance, Indigo's CEO Aditya Ghosh believes his airline's business model is quite strong along with a great hardworking team which is working on building a long-term sustainable business. "If you focus on someone else, you lose focus on what you are trying to do. We are focused on bringing 18 planes over the next 18 months and keep growing from there," he told Business Standard newspaper.
SpiceJet's Neil Mills had in a recent interview with CNBC-TV18 clarified that Indigo can never be a threat to the airline due to the strong sustainable low cost business model of the company.
