And no, there isn't. In case you don't realize, all of these promotions are trumpeted on the respective sites of each of these programs. (They're here just for the benefit of those people who don't visit those sites reguarly unless they hear on FT that there's a new bonus.) If you visit:

http://usairways.rewardsnetwork.com/

you see nothing special there (either on the front page or in the bonuses tab). So no, there's nothing right now.

Keep in mind that AFAIK there have never been bonuses going on all airlines at the same time. There's always at least one or two airlines at any time that don't have a bonus. And furthermore, even when lots of airlines have bonuses (like this month), few of them are the same (and they're generally far from all being equally good).
