How to increase credit limit on Kotak Mahindra credit card?

I've held this card for 3 years. Quick reality check: the welcome benefit is good, the first-year fee waiver is easy, but from year 2 onwards you really have to work for the milestone benefits. Don't keep it if your monthly spend drops below the milestone threshold.

I was worried about the high joining fee but the welcome benefit voucher was credited within 30 days of crossing the spend threshold. Net cost: zero. The trick is to time your application so that you make a big purchase (appliance, travel booking) in the first 45 days.
