American Airlines' flight attendants union said that a revote on contract concessions narrowly approved last week should begin "expeditiously" and that it will consider legal action if the company tries to implement the cuts. The Transport Workers Union also has said it will take a second vote. Meanwhile, the Allied Pilots Association, which represents 13,500 pilots at American, said a new vote on its concessions isn't needed because the union president hasn't signed the agreement. American said it has "a valid agreement" with each of the unions. New votes are being considered because American didn't disclose before the voting that it planned to pay bonuses to six top executives next year and protect part of the pensions of 45 executives if the airline sought bankruptcy. The bonuses since have been rescinded.

NYSE Denies Reports of Front-Running The New York Stock Exchange said its probe of floor traders known as specialists does not focus on front-running, a practice in which a trader buys or sells a stock to profit from advance knowledge of a transaction. Instead, the exchange is examining alleged violations of specialists' "negative obligation," the requirement that they let matching buy and sell orders trade with each other and "stand out of the way," the NYSE said, denying numerous media reports of a front-running probe. The exchange, also denying reports that the probe was started by investor complaints or firms failing NYSE audits, said one of its own analysts had initiated the probe after becoming suspicious of trading in an individual stock.
