No, it is closed because of contract issues. Closed in 6 or 7 cities. Premium plaza may exit India business. Since most of private airport operators are getting into lounge business.
Plaza Platinum at Delhi has never given me access, despite my cards having it in their complimentary lounge list. They tell me to visit encalm instead.
Plaza premium has shut down, Encalm has replaced it on T3 (Int and Domestic)
IDFC Wealth, HDFC Platinum Debit, Niyo Global confirmed working on International Lounge T3.
