Ladies and gentlemen, this is your captain speaking. We are 15th in queue and should take off shortly. Thank you.”

Prior to July 2010, people flying out of New Delhi’s International airport were used to hearing an announcement like this. Airplane queues were a usual occurrence in Delhi, and the airport only managed 42 movements per hour. Today, Indira Gandhi International Airport (IGIA) handles 80 movements per hour. This progress is duly credited to the overhaul that took place five years ago. The airport inaugurated a new runway, the swanky Terminal 3 building, and renovated the existing Terminal 1 (C and D). The mandate to carry out these mammoth tasks was assigned to GMR, an Indian conglomerate by Airports Authority of India in January 2006, following an international bidding process.
