Kempegowda International Airport Bengaluru (BLR Airport) has the unique distinction of being the first Greenfield Airport in India, established on a Public-Private Partnership (PPP) model. This heralded a revolution in Indian aviation as more airports in the country were privatised, thereafter. In January 2001, Bangalore International Airport Limited (BIAL), formed under the Companies Act, 1956, was incorporated to build, own and operate BLR Airport for a 60-year concession period.
