So I have a question about having multiple priority lounge accounts thru multiple credit cards.

I have my current PP thru Citi Prestige.
I would also be able to get one thru Amex Platinum and Amex Aspire. (I have not yet actually asked for these because I already have one and didn't see the point of getting more, until now)

My questions is in regards to being able to use all three of my PP cards ( should I choose to request the other two). For example, if one of the sit down restaurant options (like in denver, JFK and MIA) also has a grab and go, would I be able to use one card to sit down and eat before my flight and then use one of the other cards (from a different CC) to do the grab and go portion and get a water and some snacks?

Does PP know that I have 3 accounts and are they all linked or would this be fair use since technically I am paying all three annual fees and this is a benefit of each card.
