Indian airport sector to require USD30bn investment over next decade as traffic set to treble

India's major cities will need additional airports with traffic in the high-growth market set to treble to 450 million by 2020 (comprised of 360 million domestic and 90 million international passengers), making it the world's third largest aviation market after the US and China. Over the next 10 years, all six metros - Bangalore, Chennai, Delhi, Hyderabad, Kolkata and Mumbai - are expected to have provisioned for a second airport and Mumbai will need to start preparing for a third, based on current growth estimates. The traffic growth is also being witnessed at several non-metros with several airports having already outgrown their existing infrastructure.
