Welcome to FlyerTalk
naison. Just to let you know, this thread should be in the
'Airlines of India' forum where you'll find all the discussions of Jet, Kingfisher, Air India etc.
I'm sorry to hear about your experience with Indigo. All I've ever heard of them is that they order 100 A320s & they plan to offer really cheap, no-frills flights. Never heard of anyones experiences with them until now.
Indeed, Indian domestic flights are on the whole very good with carriers pushing each other for higher service levels (Jet, Kingfisher...). The description you give seems more typical of a US domestic. None the less, I've had worse ordeals - 24 hour delays due to an oxygen leak in the cockpit
