I consider PP to be an insurance policy in that when I travel, I almost always have access to airport lounges by other means. The only exception I can envision are a couple airports where there's no SkyTeam affiliated lounge (including contract lounges) nor is there an AmEx lounge and the possibility that I could be rebooked during IROPs onto a carrier that isn't a DL or SkyTeam partner. I use my PP card less than once a year and I have been flying between 100,000 and 350,000 miles per year.
