• US Airways' credit card, free for the first year, comes with 15,000 bonus miles after the first purchase plus 10,000 additional miles if you transfer a balance from another credit card, plus coupons for two $99 companion fares when a full-fare ticket is purchased, and access to the quickie lines normally reserved for elite and first- or business-class fliers.

• American is waiving the fee for the first year and offering 20,000 bonus miles, a $50-off certificate and a certificate for a free domestic companion ticket when you buy a full-fare ticket for $299 or more.
