Southwest Airlines, the Dallas-based airline that bills itself as the nation’s biggest low-price carrier, announced a $10 round-trip fare increase to offset higher fuel costs.

This is the latest of several airfare increases since December.

Several airlines, including Continental, Delta and United, matched the domestic airfare hike of $4 to $10 launched this month by American Airlines.

Last week Delta launched a $120 round trip fare increase on business-class tickets, and several other airlines followed suit. But by this week, United Airlines and Continental Airlines canceled the business-class fare increase, prompting other airlines to either scale back or kill the raise completely.
