For those who don't have access to airport lounges all over the globe, Priority Pass is a program where you can by access to lounges easily. You can either access lounges on a pay as you go model, or have it covered as part of a higher tier membership.
With the relaunch of The Freddie Awards in 2012, Priority Pass (as a sponsor) is offering 20% off their annual membership fee to new subscribers.
Details of the program is available at the link above, and while this may be of interest only to frequent travelers who've not been loyal enough to one airline to have gratis lounge access, everyone I know who uses it gets good value from the program, and 20% off the joining fee is nothing to sneeze as.
