I did a thorough check now and as you mentioned cant see many india airports. The only one that shows up is nagpur airport.See why I asked you to check for domestic lounges on priority pass app was, as I have hdfc diners card and almost all domestic lounges are available using this card arrival and departure both,
But in digital priority pass app, it doesn't show any lounge in india. Pic attached
So i guess pp of yes marquee cant be used within india (Atleast not using pp digital membership)
