Hmmm.......
Indigo already has 100 A320 on order from the 2006 air show of which 39 have been delivered
Then last year they order another 180 A320 the largest aircraft order in history
Why would they want another A320 order ?
Perhaps this time they are confirming the order as the 180 A320 NEO was an MOU only .
The ATR 72 has been in the Indian market for quite some time however the ATR 72-600 will be a new entry
