A SpiceJet Airlines aircraft flies past hotels being constructed on the way to landing at the Indira Gandhi International Airport in New Delhi April 1, 2013. A number of the 12 newly-built or planned hotels next to India's busiest airport, at a cost totalling more than $2 billion, have been unable to open as they await security clearance from police worried about their proximity to an active runway. The cluster of hotels known as Aerocity, on a site bigger than 40 American football fields, was approved by the government six years ago. Picture taken April 1, 2013.
