Thanks hitesh bhai. Just to add to the discussion, and I don’t know how much these sort of things actually work in stock picking, but i being a frequent flyer, have found that these lounges are packed. Recently at Mumbai airport, at 6 in the morning the lounges are fully occupied. Some carry so many credit cards, and keep others waiting in the queue, till finally one credit card works. Same with Delhi and Ahmedabad airport. So business wise, as one sees with his own eyes, this is a decent business to be.
The problem here I find is that they may be squeezed by credit card companies. Also the credit card companies have reduced the complimentary access ( i used to get 3 per quarter before COVID, which I recently found out has been reduced to 2)
