Fuelled by a slew of discount offers and in spite of an increasing financial burden, low-cost carrier (LCC) SpiceJet beat Jet Airways to become the second-largest domestic airline in July. Its share of the market in the month stood at 20.9 per cent, compared with the Jet Airways-JetLite combine's 19.6 per cent.
The price war playing out in Indian aviation space and the impact of SpiceJet's frequent discount offers on other LCCs could be gauged from the fact that the market share of leader IndiGo also declined marginally to 30.7 per cent in July from 31.6 per cent the previous month. The share of GoAir, another LCC, also saw a slight decline, from 10.1 per cent to 9.2 per cent.
