After low-cost airlines, it is the turn of no-frill and low-cost airports. In a bid to encourage regional airlines and provide air links to small cities and towns, nearly 25 greenfield or unutilised airport projects have been identified by various states, which will be up for bidding by the private sector. …

A no-frill airport is built at a minimum cost and allows operation of small jets as well as slightly bigger aircraft like Boeing’s B737 or Airbus’ A320. The investment in such an airport could range from Rs 40 crore to Rs 100 crore. …

The places identified for the purpose include Hassan, Shimoga, Gulbarga, Bidar, Mysore (all in Karnataka), Shirdi, Jalgaon, Solapur, Akola (all in Maharashtra), Kannur (Kerala), Madurai, Tiruchirapalli (Tamil Nadu), Rupsi (Assam), Ajmer, Mount Abu, Kailashar (Rajasthan), Behala, Cooch Behar, Malda (West Bengal), Jharsuguda(Orissa), Muzaffurpur (Bihar), Kamalpur (Tripura) and Passighat (Arunachal Pradesh). …

A budget airline executive said, “A low-cost airport can be constructed at a cost of Rs 100 crore, including land cost. Such an airport can increase its revenue through retail outlets, entertainment sources and hospitality projects.” …

A government official said the airports could act as operational bases of regional airlines. “The identification of regional hubs could be made on the basis of origin-destination surveys, traffic demand and the requirements of airlines,” he added.
