Air India is in the process of phasing out its Classic A320 aircraft that are over two decades old.
By the end of this fiscal year, four of these aircraft will be removed from the current fleet of 15, with all being phased out by 2019.
The other Airbus in its fleet are 22 A319s, nine A320 twin classic and 20 A321s.
Over the next three years Air India will add 29 narrow-body aircraft to its fleet – 14 of which will be the fuel efficient A320neo.
An airline official said: “So far we were unable to replace these planes as taking them off would have resulted in reduction in capacity, particularly in the fast growing domestic market.
“But with as many as 19 more A320s going to join the fleet by 2019, the old planes can be retired without curtailing the schedule.”
