Overview ( Based in Dallas, TX, Southwest Airlines ( LUV Quick Quote LUV - Free Report) ) is a low-cost airline provider mainly servicing the United States and “ten near-international” markets. Southwest provides short-haul, high-frequency, point-to-point, low-fare services. The company’s point-to-point route structure includes services to and from many secondary or downtown airports such as Dallas Love Field, Houston Hobby, Chicago Midway, Baltimore-Washington International, and Ft-Lauderdale-Hollywood. Low Cost = Low Performance ( Low-cost carriers like Spirit Airlines ( SAVE Quick Quote SAVE - Free Report) ( ) and Southwest Airlines have been dramatically underperforming their larger peers such as United Airlines ( UAL Quick Quote UAL - Free Report) ). What is Behind the Underperformance? Unprofitable and moving in the wrong direction In Q4, Southwest Airlines swung to a loss for the first time in three quarters. The 38-cent loss was wider than the Zacks Consensus Estimate of 3 cents. Adding to the disappointment, Southwest earned has seen three straight quarters of negative EPS growth. Operational Disruptions Massive flight cancellations due to extreme winter weather conditions adversely impacted Southwest’s operations. Because Southwest is more focused on one part of the globe when compared to its larger counterparts, the company suffered more. Nearly 17,000 flights were cancelled in the last ten days of 2022 – equating to a pre-tax negative impact of approximately $800 million. In Fighting & Bad Publicity ( Southwest is known and loved by its customers because of the laid-back nature of its flight attendants and employees. This laissez faire attitude is that Southwest management has found that many customers appreciate a less stuffy environment. However, that may change soon. Southwest pilots and employees are seeing little progress in trying to reach a new contract deal. If a strike is to take place, it will lead to even higher costs – especially since competitors like United and American Airlines ( AAL Quick Quote AAL - Free Report) ) have already reached deals with their respective unions. Margins are Being Squeezed Rising fuel and labor costs are causing Southwest’s financial efficiency to take a significant hit. In fact, LUV’s return-on-equity of 5.81% pales in comparison to the S&P 500 Index’s 26.2%.
