frankly, I dont know as I haven't tested it yet.
Either way, it is safe to swipe the Marquee CC for dom & int lounges (for int lounges you just need to let them know that you are a PP customer and then handover your marquee CC to the front desk).
PP (physical or digital card) usually is chargeable when used inside India (be it at dom or int terminals) apart from a few bank's linked PP like Magnus, where you can used Magnus issued PP to access a few lounges for free inside India. But again as I said, it's very very few and not the nrom. Hope this clarifies your query?
