A Parliamentary panel on Monday asked the civil aviation ministry to cap the upper and lower levels of airfares. “The committee recommends that there should be a mechanism with the ministry such as capping of upper and lower prices to stop the practice of predatory pricing or the sudden surge in prices… a close watch has to be maintained by the DGCA & the ministry and a mechanism should be devised to monitor the websites of various airlines to prevent them from misguiding passengers,” it said.
