Southwest Airlines more than doubled its fourth-quarter profit as more passengers paying higher fares filled its planes during the busy holiday travel season.The Dallas-based carrier reported that net income rose 171 percent to $212 million in the quarter as revenue grew 6 percent to $4.4 billion.Southwest, which expects to complete its integration of AirTran Airways this year, said strong travel demand and solid bookings have continued into 2014.“Our outlook right now for the economy is very stable,” Southwest Chief Executive Gary Kelly told analysts and investors on a conference call Thursday morning. “The uncertainties we had a year ago, hopefully, they won’t return.”This month, Southwest plans to unveil its new international reservation system and will migrate AirTran’s international flights into the Southwest system. AirTran serves Mexico City, Cancun, Punta Cana, Nassau, Montego Bay, Aruba and San Jose del Cabo.“We are days away from announcing what our international plans are,” Kelly said, adding that Southwest hopes to expand international service in 2015, particularly at Houston’s Hobby Airport, where it is building a five-gate international terminal.International service won’t come to Dallas Love Field. The Wright Amendment restrictions on international service will remain in place even when domestic-flight restrictions are lifted in October. Kelly, who noted that the Wright Amendment restrictions will go away in 38 weeks, said the carrier is not ready to reveal its plans for Love Field and which new routes it will operate there.Cowen and Company analyst Helane Becker told investors that she expects the international announcement next week and believes the airline’s growth will boost its stock.“We believe this international expansion will be a game-changer for the company,” Becker wrote in a research note to investors Thursday.Shares of Southwest (ticker: LUV) closed at $21.24, down 53 cents Thursday.The airline said that its average fare increased 5.4 percent to $156.05 and that it had over 33 million passengers, up 1.3 percent for the quarter. It also added capacity to its network, up 2.2 percent, and planes were slightly fuller, with the load factor up 0.8 percentage point to 80.4 percent.Southwest said it paid less for fuel in the fourth quarter, about $3.05 a gallon, compared with $3.32 a gallon in the fourth quarter of 2012. The airline expects fuel costs to remain stable in the first quarter, around $3.05 to $3.10.Excluding one-time accounting items, Southwest said its net income was $236 million, or 33 cents per share, beating Wall Street estimates of 29 cents per share, according to FactSet Research.For the full year, Southwest posted a $753 million profit, up 79 percent from 2012. Total revenue also grew 3.6 percent to $17.7 billion.With the company’s strong financial performance, Southwest gave employees $228 million in 2013 as part of a profit-sharing plan, up from $107 million in 2012.
