Methodology of ticket fares: 40 per cent of the seats in any flight would have to be sold at the mid-point of the lower and upper air fare limits prescribed for any route by the authorities.
In the case of a Delhi-Mumbai flight, the minimum fare will be Rs 3,500 and the maximum fare will be Rs 10,000. Thus, for a Delhi-Mumbai flight having a total of 180 seats, the ticket fares will range between Rs 3,500 and Rs 10,000. Moreover, at least 72 seats (or 40 per cent of all seats) will have to be sold at a price less than Rs 6700.
