United Airlines Leads Fare Rate Hikes

United Airlines led American Airlines and Continental Airlines Inc. in raising some U.S. fares as much as $200 round-trip, one of the largest business-fare increases in at least seven years, amid higher wages and other costs. United said prices of one-way tickets bought fewer than three days before travel will rise by $50 to $100. AMR Corp.’s American and Continental matched the increase. Delta Air Lines Inc. said it raised business fares 10% in some markets, and Trans World Airlines Inc. is studying the increases.
