Generally 1 rupee. But depends on the flights that you redeem it for.
I have seen some flight are cheaper to book through bluechip points than through cash. Selecting cash or by bluechip point options is there in indigo when you search itself. Can get more value if you select the flights judiciously after comparing both.
Very good mone by Swiggy, I was a Zomato person but since this Collab shifted to Swiggy as indigo bluchips redemption are are also decently structured currently
