That makes me think that the popularity of the CSR is cascading to PP so there are going to be a lot more people at these lounges Seatac Board Rooms are already crammed and have fun at DFW when you get put in the "closet" room (as the reception desk calls it). That is already standing room only.

At least Amex Centurion has dedicated lounges, Chase may need to start the same... . Hint: at Seatac, The Club in A gates is usually wide open but it is a LONG walk and not near anything but United and a couple Delta flights.
