With a strike by thousands of mechanics in its third day, Northwest Airlines Corp. on Monday faced its biggest test yet in its bid to keep operating, but the stock rallied as investors bet the carrier would win.
The No. 4 U.S. airline kept flying over the weekend without any major disruptions as it called in 1,500 replacement workers in a bid to weather the first U.S. airline strike since 2001, but Monday would be its busiest flying day yet.
