I just called them. They said their team is working on a mobile app that will support credit cards from multiple banks, just like their site. The currently available app only supports direct DF membership and the ICICI DF co-brand card.I’m new to DF. While this method is for the DF website, is there also a way to use the DF app for lounge access provided through credit cards? It needs the membership number and PIN which l don’t have, can DF support provide me those details?
