US Airways has a four day sale (through December 13, 2012) on club memberships, whereby they’re offering two additional free months (for a total of 14 months) plus 3,000 PQMs for any new membership. Simply use promotion code 2FREE when enrolling.
The membership costs are as follows:
I still think it’s a much better value to get the American Express Platinum card, which gets you US Airways Club access, given that the annual fee is $450 and you get a $400 airline fee credit (which can be used creatively), essentially bringing down the cost to $50 for the first year. But if you’re short of PQMs for the year this might not be a bad mileage run alternative.
