I have a hdfc DCB through iim alumni offer. I don't own any paid CC. I accepted it only because it was LTF and it has a big Cc limit of 6lakhs. In last 1 yrs it got rejected at multiple places. In Spain - valentino store while purchasing some 450 euro stuff.

In thailand while purchasing phone. In Indonesia app while booking train ticket. Very recently another SE airlines website while booking flight. Ticket cost was 22k in airline site. DCB didnnot work. In hdfc smartbuy it was 25.6k. I did not want the 15% reward as the price was already hiked up. I have scapia with 20k cc limit. So scapia didnnot work. So, I had to use savings account to book the 22k ticket.

DCB has very low acceptance in my experience. Your experience may differ. I buy 6-7 international flights a year and few other international purchase. Shall I request for HDFC infinia even if it's paid ? Or any other visa card like rbl safari ? Plz suggest.
