I have upgraded to Infinia from Regalia recently. I didn't get LE for last two years. My limit was at 6.7, had I got LE, it would have crossed the minimum 8L limit.
I saw the required conditions on Twitter shared by card maven or Technofino
8L and 2.7L in hand salary
Or
8L and last 6 months more than 7.5 L spends.
I have contacted RM. It was utter useless and water of time. She mentioned it would require more than 3L in hand Salary.
Upgraded to Classic Banking a month before planning to upgrade.
I had also hit 8L spend milestone on my existing Regalia.
Sent out a mail to Grievance redressal, they forwarded me the application to fill and there was lot of back and forth as they wanted me to send it to Chennai branch and I have criticized them why they aren't doing it completely online when IDFC, Onecard take 10 minutes for the approval and completely online onboarding process.
They were nudging towards the DCB, and even I thought that I would do the same as the salary criteria won't be met without including the bonus and no where close to 7.5L spend milestone in 6 months as well.
I have also applied for SC Ultimate meanwhile as a backup card for DCB.
I thought why not give a try for Infinia as I have been using HDFC card for 10 years and also a personal loan running now. I had paid off a personal loan, couple of credit card jumbo loans over these years. If rejected, I can still apply for DCB.
Guess that relationship with them helped me for the upgrade.
