I did not use Indigo as it was a complete surprise that I was put on economy at indigo when i sorted for business class only. Apparently your aggregation of travel agencies does not preclude validation of their process. I ended up totally changing my flight back from Chennai. Kayak used to be a place I could trust. Unfortunately not anymore. Glad you sold and turned into the Amazon of travel How nice for you.
