They are running a campaign that 50% off on ICICI card on the base fare for Indigo, jet etc.
I was  trying to book a ticket and found that the Indigo site was offering it for Rs. 2500 and ezeego for 2704 with Rs. 250 as off in the offer :). As you can see they charge the ticket price higher for whatever reason adding some transaction charge of Rs. 204 and gave a discount of Rs 250 so effective discount was only Rs. 46. This information is not very open.

Beware of the customer care, it was the worst before but now they say that they have improved upon it a lot. Before booking make sure you call them and check if they are reachable otherwise you may get stuck.
