Southwest Airlines is making more money than it did a year ago because of higher fares and the acquisition of AirTran Airways.
But fuel costs are up 64 percent from a year ago, and Southwest's profit isn't as big as analysts expected.
Southwest said Thursday that it earned $161 million in the April-through-June quarter. That's up from $112 million a year ago.
The average fare went up about 8 percent. Southwest and other airlines raised prices several times this year to offset rising fuel costs.
