Delta Air Lines Inc. raised domestic air fares by $5 each way late Thursday, and American Airlines, the nation’s largest carrier, matched the increase on Friday.
United Airlines, the No. 2 carrier, was studying the increases, said spokesman Jeff Kovick. Two smaller carriers, Alaska Air Group Inc. and Midwest Airlines, matched the Delta increase.
Northwest Airlines Corp., Continental Airlines Inc. and US Airways Group Inc. remained on the sidelines at midday Friday. A spokesman for Southwest Airlines Co. said the Dallas-based carrier had no plans to raise fares immediately.
