US Airline Stocks Soar Amid Record Travel and Optimistic Outlook for 2025

Airline stocks in the United States have outperformed the broader market in 2024, marking their best performance in a decade. The S&P Supercomposite Airlines Index has surged by 60% this year, far outpacing the 27% gain of the S&P 500 Index. This stellar performance mirrors 2014, the last year the airline industry outpaced the broader market to such an extent. United Airlines Holdings Inc., leading the charge, has seen its stock rise by a remarkable 144%, making it the fourth-best performer.

The surge in airline stocks coincides with a record-breaking year for travel. According to the US DOT, the TSA recorded its 10 busiest travel days in history during 2024. This unprecedented demand underscores a resurgence in consumer appetite for travel, even after a mid-year slump.

One of the key factors driving airline stocks is constrained growth in seating capacity. Carriers have been cautious, cutting unprofitable routes and focusing on optimizing existing operations. According to Barclays Plc, seat growth for US airlines is expected to remain below 3% in 2025, a figure that lags behind pre-pandemic trends. This disciplined approach to capacity management has contributed to the industry's strong performance. "We see airline fundamentals considerably improving into 2025, supporting a strong margin and earnings outlook for many carriers in the sector," wrote Barclays analyst Brandon Oglenski.

Investors are showing increased confidence in legacy carriers such as United Airlines and Delta Air Lines, known for their premium travel offerings and international networks. Alaska Air Group Inc. and Frontier Group Holdings Inc. have also garnered attention due to enhancements in their frequent flyer programs. Deutsche Bank predicts that major players like Delta, American Airlines, and United will dominate 2025's profits, commanding nearly 90% of operating and pretax earnings. This projection highlights a widening gap between the industry's top performers and smaller competitors.

Recent financial updates from key airlines have painted an optimistic picture. JetBlue Airways Corp., Southwest Airlines Co., and American Airlines Group Inc. have all raised their earnings forecasts for the fourth quarter. These revisions are attributed to strong holiday travel demand, higher airfares, and declining fuel prices. Delta Air Lines will begin reporting quarterly results for the group on January 10, setting the tone for what is expected to be a robust earnings season.

Industry leaders are also optimistic about the potential regulatory environment under President-elect Donald Trump. His promises of deregulation and lower taxes are viewed as favorable for the sector. Executives anticipate these policies could further boost demand and support consolidation efforts, unlike the more stringent oversight under President Joe Biden's administration. Grace Lee, portfolio manager at Columbia Dividend Opportunity Fund, echoed this sentiment. "In general, I am more confident, and a lot of the management teams we've talked to seem to have more optimism about improving business and economic activity," she said.

Despite the positive momentum, risks remain. Airlines face challenges such as rising costs tied to maintaining older aircraft due to delivery delays from Boeing Co. and fluctuating oil prices. These factors have kept some investors cautious, even as the industry rebounds. The sector is also navigating a competitive landscape where low-cost carriers are pivoting toward premium offerings to attract high-budget travelers. This shift reflects an effort to capitalize on the so-called "revenge travel" phenomenon, where consumers prioritize experiences over savings.

Investor sentiment toward airline stocks is mixed. While the US Global Jets ETF, the largest fund tied to international travel, has rallied 36% this year, short interest in the fund has surged. This indicates skepticism among some money managers about the sustainability of the current rally. Ravi Shanker, an analyst at Morgan Stanley, noted that institutional ownership of airline stocks remains low among traditional investors. However, hedge funds and retail investors have shown growing interest. "The bar to beat investor expectations is no doubt higher than it used to be 12-18 months ago," Shanker said, "but it is still low overall."

The US airline industry has undergone a remarkable transformation in 2024, rebounding from the challenges posed by the pandemic. While the S&P Supercomposite Airlines Index is still down more than 10% from early 2020 levels, the current trajectory signals a bright future. As airlines head into 2025, the combination of strong demand, disciplined capacity management, and favorable regulatory expectations positions the industry for continued success. Investors and analysts will closely monitor how airlines navigate these opportunities and challenges in the months ahead.
