Domestic airlines have proposed a massive hike in air fares. AIR correspondent quoting official sources reports, the Directorate General of Civil Aviation (DGCA) which received the proposals on Thursday is unlikely to give its nod. DGCA sources also say, the civil aviation regulator is likely to shoot down the proposed price bands and may ask the airlines to rework them keeping the interests of passengers in mind. The fare bands proposed by airlines are for the first time based on distance-based slabs. Civil Aviation Minister Praful Patel reiterated that the airlines would not be allowed to charge exorbitantly. Mr Patel said DGCA will not allow any predatory or exorbitant pricing. He said if there is something lacking, necessary correction will be made. The domestic airlines came out with the proposal after they were asked by the DGCA to submit the planned price bands on various sectors after some of them resorted to steep hike in airfares even during the non-peak season.
