Getting into a US Airways airport lounge is cheaper through August 31. Day passes are $15 off — $25 per person instead of the normal $40 fee — if you mention promotion code ES25 at the club front desk. Details are here.

Buying a one-day pass is just one of five ways to lounge in airports. But for one-day passes, this is relatively cheap. A nice feature is that it’s valid for the whole day, at all club locations, and not just for one entry.
