American, Delta raise fares, citing higher fuel costs
2 November 2007American Airlines increased fares Thursday due to surging crude oil and jet fuel prices, prompting Delta Air Lines to quickly follow suit and very likely setting a new round of industrywide price increases into motion.
American raised domestic fares by $10 one way and $20 roundtrip in an effort, the airline said, to recover some of the costs associated with recent large increases in the price of fuel. Delta raised its fares by $10 in most domestic markets, a spokesman said.
