An airfare-watching FBvian sends along this NYT story (reg. req.) with the observation:
The Love/DFW fight may be the least of AA’s worries when it comes to competing with SWA. IMHO, Southwest just keeps on innovating, while the rest of the legacy carriers are doing little more than reacting, and that explains a ton of Southwest’s success. And the legacy carriers’ continuing flirtation with the bankruptcy courts.
