Aiming to attract more fliers and achieve higher seat occupancy in its flights on trunk routes, Air India has decided to lower its last minute ticket fares to the level of 2-tier AC of Rajdhani trains.As part of the pricing strategy, the state carrier will drop fares on four key routes–Delhi-Mumbai, Delhi-Chennai, Delhi-Kolkata and Delhi-Bengaluru–four hours before the departure of flights to these destinations.Air India Chairman and Managing Director Ashwani Lohani said the move is aimed at providing relief to the passengers from last minute sky-rocketing fares and also to fill the vacant seats.He said Air India has an average load factor of 74 per cent across its domestic network while the seat occupancy on these trunk routes stands at around 80 per cent and it is the airline's objective to fill these remaining seats as well.Last month, Air India had floated a limited period scheme to fly unconfirmed passengers of the Rajdhani trains at the fares matching with the AC first class ticket prices.Under the 'Super Saver' scheme, which started from June 26 and end on September 30, passengers of the Rajdhani Express trains who have wait-listed ticket could book four hours prior to the flight departure at a fare which match with the ticket price of Ist AC Rajdhani trains.
