Airfare Increases Follow Rise in Oil Prices

Airlines are responding to oil's latest surge by pushing ticket prices even higher. Round trip domestic fares began rising $10 to $20 or more as crude futures crossed the $100 a barrel mark. Several major carriers increased their prices, each citing higher fuel costs as the reason. The widespread increases follow nearly two dozen attempted systemwide fare increases in 2007, or about double the number during the previous year, according to data compiled by FareCompare.com, which tracks airfare changes.
