New aircrafts are coming and old are going back so it turns out to be the same number...!!!and if I am not wrong then 15 would be too high a number for the 320...I think they should be working with maybe 12 or 13...!!!
About the backlog...well it's not clearing but it's just increasing by the day...I have a friend of mine who is 154 in the waiting list ....so u can judge for yourself..!!
