As a part of the Google organised Great Online Sale Festival, Indigo is offering 15% discounts on base fare on all domestic and international flights. To get these discounts, you need to be booking a roundtrip, and use promotion code 6EGOSF to avail the discounts. The tickets can be booked between 10-12 December 2014, for travel between 15 January 2015 to 30 June 2015.
Now, unlike with the Jet Airways’ discount, the Indigo discount is slightly more difficult to obtain. Firstly, the discount can only be applied to round trips, and on regular fares. Indigo also offers round-trip fares which are slightly discounted (called Return Fares). Secondly, your discount does not show up till you get on the payment page, which is the third screen of the booking process. Here, you need to battle some scripts on the page to be able to plug in the promotion code and only then do you get the discounts. It isn’t very different from the regular Return fares I’d say.
Take this example. Here are roundtrip fares on the dates which comply with the rules for GOSF benefits.
Here it is after applying discounts for the GOSF (non-roundtrip fares, applied on return travel).
There is hardly a difference, and I don’t see why Indigo would want us to jump the hoops to be able to get to this discount which is nothing better than their usual offering. Of course, your mileage may vary!
