Both American and Delta are running promotions right now for lounge memberships.
American is offering 3,000 bonus AAdvantage miles for new Admirals Club memberships through December 31, 2012 (renewals don’t seem to qualify). Registration is required using promotion code QPN12, and the bonus miles should post 6-8 weeks after the end of the promotion.
The cost for Admirals Club memberships is as follows:
Delta is offering either two additional months or 1,500 bonus Medallion Qualifying Miles on a new or renewed one to three year SkyClub membership.
Delta’s SkyClub pricing is as follows:
If you were thinking of getting a membership or renewing this would probably be a good time to do so. That being said in both cases I think an American Express Platinum card is a better value, as it gets you access to American Admirals Clubs and Delta SkyClubs, and has an annual fee of $450. You then get a $200 airline fee credit per calendar year, which means the first year’s annual fee will get you $400 worth of airline fee credits, essentially making the annual fee $50 for the first year (and $250 for each subsequent year). That’s a much better value than either membership, in my opinion!
