"MIAL is predicted to generate as high as USD 10 billion from total (direct, indirect & induced) value-added revenue of airport operations by FY23, or about 4.02 per cent of Maharashtra's GSDP," National Council of Applied Economic Research (NCAER) said in a report.
The report pegged the total revenue of MIAL to rise to Rs 4,140 crore by FY23, when its aeronautical revenue is slated to touch Rs 1,718 crore and non-aero to Rs 1620 crore.
In FY10, MIAL's total revenue stood at Rs 1,314 crore, aero revenue at Rs 424.2 crore, while the non-aero income was a little over Rs 714 crore, according to the report.
Maharashtra is expected to continue to reap windfall gains from the airport, which has already helped it to top in tourist arrivals at 5.12 million in 2012, which was close to a quarter of the travellers who came to the country, it said.

On the other hand, non-aeronautical revenue per passenger shows a continuous rise since FY11 due to better revenue collection from retail licences.
