I booked for 2 In Feb starting for Mid Feb dates with 30k+30k points, While my relative also took the same Air India flight which cost him roughly 60k INR. Might have been higher prices for booking early dates but I remember there were no flights cheaper than 50-60k in Feb 2023 hence I utilized those points.
The thing is, the points required remained the same even when flights were cheaper and costlier.
