American Airlines Increases Domestic US Fares Wednesday September 22, 3:38 PM EDT FORT WORTH (Dow Jones)--AMR Corp.'s (AMR) American Airlines raised most domestic fares, saying the hike was necessary to offset the high cost of jet fuel. In a press release Wednesday, the airlines said it was raising fares within the U.S. and fares from the U.S. to Canada by $5 one way and $10 for a round trip. Each one-cent rise in the price of a gallon of jet fuel costs American more than $30 million a year. Crude oil prices remain well above $40 a barrel, up substantially from a year ago, the airline pointed out. If the current increase in oil prices year-over-year were to remain in place, AMR Corp. would incur more than $1 billion in added fuel expense over the coming year, the company said. -Anjali Cordeiro; Dow Jones Newswires; 201-938-5400; AskNewswires@xxxxxxxxxxxx Roger EWROPS
