ClearTrip is so easy to use that it apparently doesn't believe in confirmation dialogues -
Looks like cleartrip.com isn't bad at all once you get past the call centre. Narla contacted them via the feedback section of their website and this elicited a very quick response. They've been exceptionally helpful and have offered to refund Rs. 4000, half the cancellation charge due. This is pretty decent of them, keeping in mind the fact that cleartrip.com cannot recover the cost (it's already been canceled at the airline). Good stuff!
