While free land should be provided by state governments for developing or extending runways, the Airports Authority of India (AAI) should be exempted from municipal taxes, officials said.
The state or local authorities should also ensure power and water supply and proper roads to the airports if enhancement of air connectivity to Tier-II and III cities has to be promoted, they said.
The AAI could waive these charges if these conditions were met by state governments, the officials said, adding that the move could lead to a reduction in the operating costs of the airlines by 8-10 per cent.
The ministry has been considering exempting airlines from landing, parking and navigation charges to promote regional connectivity. Such charges account for about 10 per cent of airline costs.
The ministry has engaged global consultant Deloitte Touche Tohmatsu India to identify the factors inhibiting the growth of domestic connectivity, especially to the remote areas and smaller cities.
In its report, Deloitte has identified some 85 to 100 secondary cities with good economic prospects that could ensure a customer base for airlines, but most of them do not have airports.
