Yes, a Southwest Visa from First USA Bank in Wilmington DE allows up to five lifetime Rapid Rewards credits for balance transfers (ie, up to $5,000). I recently received an offer by mail from Citibank promising American AAdvantage miles for balance transfers (see my posting under the American Airlines board). Since I haven't heard from them yet about my application, I can't confirm the details of that offer. I'll post an update here when I do.
