Again between 2003 and 2010, it purchased 43 planes of the A-320 family -- that is A-320s, A-319s and A-321s. At present, it has 18 A-320s, of which 12 are owned and six leased, 24 A-319s (19 owned and five leased) and 20 own A -321 aircraft in its fleet. The sources said the deliveries of these 19 leased aircraft should preferably begin from the fourth quarter of this year when it would require seven of them. It proposes to acquire four more in 2014-15 and eight more in the next fiscal in a phased manner. The decision to lease these all-economy aircraft came amid strong indications of a growth in competition from no- frill carriers, as also the entry of AirAsia India in the domestic market. The sources said the new leased aircraft could also be used to replace the ageing fleet of the same type of planes already in the Air India fleet.
