I don't know if you all use Groupon, but I do and love it. Today's New Orleans groupon is $22 for a pass to Delta's Sky Club lounge (usually $50). It's good at 50 airports and you can use it no matter what airline you're flying, as long as you use it the same day you're flying. It's good through the end of the year.
A lot of us are flying internationally and the lounges, with their open bars and free food/wifi/TV can help with the layovers and downtime!
