The Centre's crackdown against IndiGo for the chaos at airports across the country has begun. The Directorate General of Civil Aviation, the country's aviation regulator, has slashed IndiGo's winter schedule, reducing the number of flights by 5 per cent. IndiGo operates about 2,200 domestic and international flights daily. So this means a reduction of 110-odd flights daily. The slots freed due to this would be given to other airlines, the government has said.
