Since I haven't received any replies on the second question on my other post. This might be the wrong place, but not sure where else to post it.

I will be flying economy in December and I was interested in getting lounge access in IST. Is there any way I can access lougnes in IST, paying for the day, is there any sites that book these, any kind of membership.

What would be the right way to do this and what are my options.

In case credit cards are an option, I have a Blue from American Express and a basic Citi Card.

Thanks for all the help.
