Going by projections for growth of air travel, both local and international, the Delhi metropolitan area needs at least two additional airports, one immediately and another within ten years, to meet the burgeoning air travel. Ditto for Bombay. Who's going to ante up for building these? Maybe AAI should start the ball rolling with these new greenfield airports if they are so confident of their capabilities in running such complex projects - the govt should call their bluff; let them put their money where their mouths are - either put up or shut up!
