Dallas • Southwest Airlines Co. says fourth-quarter earnings fell by nearly half on higher spending for fuel, labor and maintenance.
The airline's revenue rose slightly, however, as the average fare climbed almost $8 higher than a year ago.
Southwest also said that bookings for the first three months of 2013 look strong. It said that based on bookings and ticket prices so far, a key revenue measure should rise by 2 percent to 3 percent in January compared with the same month last year.
Southwest, the nation's fourth-biggest airline, said Thursday that net income was $78 million, or 11 cents per share. That's down from $152 million, or 20 cents per share, a year earlier.
Excluding items such as fuel contracts, the net income would have been 9 cents per share, beating the 7-cents-per-share forecast among analysts surveyed by FactSet.
Revenue ticked up 1.6 percent to $4.17 billion but fell short of the $4.20 billion that analysts expected.
Expenses rose faster, however, by 3.1 percent. That includes a 4.5 percent increase in labor costs and a 13 percent jump in maintenance as the airline continued to overhaul the cabins inside many of its planes.
Spending on fuel, the airline's biggest expense, rose a modest 0.7 percent. Southwest estimated that its fuel bill in the first quarter, which ends March 31, will drop to $3.30 per gallon from $3.44 in the first quarter of 2012, which CEO Gary Kelly called "an encouraging trend."
The average fourth-quarter fare on Southwest and its AirTran Airways subsidiary was $148.02, up 5.4 percent from $140.38 a year earlier.
Passengers flew 1.4 percent fewer miles on Southwest than a year earlier, and planes were less full 79.6 percent occupancy, down from 80.5 percent.
For all of 2012, Southwest earned $421 million, up from $178 million the year before and its 40th straight profitable year, which Kelly said was "a remarkable feat and a record unmatched in the airline industry."
