Your correspondant states ***** Among these, the AAI owns and manages 5 international airports ******
Well he seems to be still living in the early 1990s! There are now 15 international airports of which the latest, Calicut (Kozhikode) got international status only a couple of days back.
Ofcourse of the 15, not all are owned by AAI. Cochin is private (CIAL), Bangalore is HAL, and Pune and Goa are defence airports. But that still leaves 11 OWNED and MANAGED by AAI!
Please dont take readers for a ride with such poor reporting and dent your hard earned credibility.
