The proposal comes in the backdrop of SpiceJet episode, which had come out with a series of low-fare offers throughout the year to beat competition and then facing cash crunch.
"Steps may be taken to fix minimum and maximum air fares.... There is a need to fix a cap on the maximum air fare of economy class at a reasonable price of around Rs 20,000 beyond which the airline should not be allowed to charge, exploiting the passengers' urgency for travel due to various reasons," the Civil Aviation Ministry said in internal note.
According to the note, the airlines can be asked to submit their break-even price per kliometer, which will depend on the service offered and the type of aircraft among other factors.
"An appropriate profit can be added to the break-even price per km and that can be minimum price per km to be charged by the concerned airline," the note said.
The note also said that the airline companies were charging very high spot fares and that there were large number of complaints received from Jammu and Kashmir and North East region, Andaman and Nicobar and several other places in the country.
"In order to remove the grievance of the passengers on account there is a need to fix a cap on maximum air fare of economy class at a reasonabl;e price of around Rs 20,000," the note said.
