I just got one and they sent me the book with the airport listings. I really think they'd sell more memberships if they made this info available to people browsing the Web site.

In short, I'm happy. They include many Presidents' Clubs, NW Clubs and Crown Rooms. There are lounges in cities I've never heard of and I'm pretty good with geography. When I leave Delhi on a 3:25 AM flight Saturday I have access to a 24/7 lounge. A decent selection at ORD and EWR, in multiple terminals. The one at MCI, my home airport, is a Crown Room which I'll probably never use- I rarely fly Delta and MCI is set up so that you really can't use Airline A's club if you're flying Airline B.

I migrated to PriorityPAss after I left me President's Club membership expire and THEN found out they no longer waive the $50 initiation fee for Silver OnePass members. I'm doubly happy with the decision now.

Do a search on PriorityPass- there some other threads on it here.
