IndiGo's assertion comes against the backdrop of some competitors rolling out a slew of low-fare offers as part of efforts to fill more number of seats, particularly during lean periods.
The Gurgaon-based carrier's parent InterGlobe Aviation is all set for a little over Rs 3,000 crore initial public offer next week.
"We don't track or chase market share... Load factor and market share (are something) we neither chase nor track very diligently," IndiGo President Aditya Ghosh told PTI.
When the capacity goes up, the market share naturally rises, especially since there is a huge unpenetrated domestic air passenger market.

About government's proposed move to put a cap on air ticket prices, Ghosh said that he does not foresee such a mechanism coming into force as pricing remains a function of demand and supply.
"There is a lot of talk on (capping the fare). I have not seen anything in reality. Now let's say it happened. Let's say there was a capping of fares or let's say airlines are told that they cannot sell at low cost, can you imagine its impact on a higher cost structure airline?," he noted.
