Thanks for your detailed response. I have few more questions :
A) Where can I find the list of lounges that are accessible through my card?
B) Can I use the Primary card and Add on card simultaneously? I am asking this because card no. of both is same.
C) If the Diners Club card is itself...
I have Diners club privelege. When I click on Lounge section in Diners Club® Travel Tools app, it redirects to Priority Pass website. Do we have to apply for a Priority Pass to access International lounge?
I have HDFC Diner's Club Privelege Credit Card. I want to access Lounge at Dubai Airport. I checked the Diner's Club app, it asks for Priority Pass details. But nothing about Priority Pass is mentioned on Bank's website. Will the card be directly accepted or I will have to apply for Priority Pass?
