yeah, the rest 2500 is holiday voucher with time limit which if used makes the card free of cost
Instead of Signature, its better to get MMT Platinum variant, 500 as joining fees which gets returned as 500 MMT My Cash which basically makes it free once the points are used
They don't give MakeMyTrip signature card free of charge
everybody has to pay 2950 joining fee which is not worth it because you will not use 2500 holiday voucher.
so you are going to lose 1450
