The aviation sector regulator has asked domestic airlines to maintain transparency in publishing fares across various categories.
"In order to maintain transparency in tariff publication, all the scheduled domestic airlines have been directed to furnish a copy of the route-wise tariff across their network in various fare categories, in the manner it is offered in the market, to Director General of Civil Aviation (DGCA) on the first day of every calendar month," said a statement from the regulator.
The watchdog said that it had received "reports of scheduled domestic airlines charging excessively high tariff for various flights across their network during the high demand period, causing lot of inconvenience to the travelling public and drawing adverse comments on air fares".
Airlines would also be required to publish air fares on their websites or in newspapers.
"Any significant and noticeable change in the established tariff so filed with DGCA shall be reported to DGCA within 24 hours of effecting such changes," the statement added.
