This was my first year of going with any lounge membership and I went with PP. I travel alone most of the time and the access that PP provided is far greater than the standard BR.
As a frequent traveler to EWR, the lounge in the same terminal as the AS gate is a UA RCC and that has been very helpful. The agents are always very friends when I enter a BR and always ask if I have ever visited or would like for them to show me around.
I am also going to enjoy my PP on a last minute trip PDX-DEN-AUS (on UA) and returning AUS-LAS-SEA (on US). Hope all goes well and I'll at least get to check out some other lounges.
