that's just the kind of comment that comes from a misunderstanding of fleet management.
i cannot understand the kind of venom that indigo is getting here. they're one of the top airlines in India, with a robust and profitable business model, and a good customer base.
even if you consider this is on top of their original 100 A320 order due to be completed by 2015, this isn't exactly illogical. they are continuing a proven formula that has given them (and others such as Ryanair and Airasia) success. In the LCC world, volume is king, and India at present still has no such volume operator.
from my end of the LCC world, this is definitely audacious, but it is not misplaced. it is going to take a lot of hard work for Indigo to make it work.
what would have been illogical is if indigo ordered widebodies!
