Union Civil Aviation Minister Praful Patel has said that air-fares that had risen astronomically in the last month will stabilise within a week. He told reporters in Mumbai that he was sure that airlines will take corrective action in week's time. If it is not done, the Directorate General of Civil Aviation – DGCA – is empowered to take actions for the benefit of air travellers. He said the regulator is not helpless and it should not be presumed that the regulator cannot take action. He was sure that they can act when the situation warrants. Meanwhile, DGCA has called top executives of all Indian carriers for a meeting today and on Monday, asking them to explain why they have proposed such high fares. While SpiceJet, GoAir and IndiGo officials are slated to have discussions with the DGCA today, full-service carriers– Air India, Jet Airways and Kingfisher Airlines– will meet with the regulator on Monday. Patel had earlier said that either exorbitant fares or predatory fares by deliberately lowering of ticket prices below the actual costs to out-compete other airlines will not be allowed.
