Hey guys.. Never travelled to CCU before so wanted to clear a couple of things..

I land at CCU at 0800 and I'm connecting to Shillong on AI at 1200.

I believe there are 2 Clipper lounges in Domestic (1 before security and a 'Club Lounge' after security).

I plan to access these lounges using my Mastercard.. Do both these lounges allow Mastercard access (The mastercard website lists them both) and which one is better?

Thanks!
