Northwest Airlines Hikes Fares For US, Canada Thursday February 24, 3:02 PM EST NEW YORK (Dow Jones)--Northwest Airlines Corp. (NWAC) increased fares on flights in the U.S. and Canada as the spring travel season approaches. Kurt Ebenhoch, a spokesman for the Eagan, Minnesota, carrier, said Northwest earlier Thursday boosted fares for routes shorter than 1,000 miles by $5 each way. For longer routes, the airline increased fares $10 each way, he said. The fare increases are for all markets in the U.S. and Canada and all fare classes. "We are coming into a historically strong travel period," Ebenhoch said, which prompted the fare increases. Further, he said, the higher fares will offset some higher fuel costs. Roger EWROPS
