Airlines raise round-trip fares14 January 2007
American Airlines, United Airlines, Delta Air Lines Inc. and Northwest Airlines Corp., four of the five largest U.S. carriers, raised round-trip fares by as much as $10 in the industry’s first major boost this year.
United increased fares across its network, a change matched today by Delta. AMR Corp.’s American changed prices only in markets where it competes with low-fare airlines, adding $6 to tickets for flights of 1,000 miles or less, and $10 on longer routes. Northwest adopted American’s change.
