The study examines the economic impact of the Delhi and Hyderabad international airports on the national and regional economies in terms of contribution to income and employment. A passenger survey was also carried out in both the airports covering more than 4,000 passengers to capture their profiles. In case of Delhi International Airport, we found that the airport’s operation service has contributed significantly to both national and regional GDP. It contributed Rs 294.7 billion (about 0.45%) to the national GDP and around 13.53 per cent relative to Delhi’s GSDP in 2009–10. Overall, it contributed Rs 42.9 billion directly through value added (air transport and air services), Rs 77.2 billion indirectly through supply chain (multipliers impact) and Rs 174.6 billion through tourism and investment (induced impact).
