Is access to Plaza Premium still possible at DEL via credit cards? I was told in December that it had been stopped. When I spoke to a lounge manager on the phone he said it was pulled by Mastercard/Visa.
Mastercard still has the agreement. Visa moved to Fuel bar(DOM) / DareDevils Bar (INT). But in HYD, Visa Still gets you to Plaza Lounge
But not all mastercards are allowed in DEL (Eg: Citi PM has access to Plaza Lounge in 1D, not/none in T3). So check with your Bank.
