3 Executive Summary
3.1 Introduction
The airline sector is a dynamic and highly competitive industry, exemplified by the diverse operational scales and market reach of its leading carriers. In global terms, United Airlines (UAL) stands among the top contenders, carrying nearly 174 million passengers in 2024, positioning it just behind American Airlines and Ryanair and ahead of Delta Air Lines and major Asian carriers. Domestically, UAL holds one of the largest shares of the U.S. market, closely competing with Delta and American Airlines, each capturing just over 20% of the market. JetBlue Airways (JBLU) and SkyWest (SKYW), while significantly smaller than UAL, demonstrate the sector’s diversity: JetBlue carves out a notable niche with roughly 5% market share focused on hybrid low-cost service, whereas SkyWest operates with a regional business model and holds about a 2% share, supporting major airlines through contract flying and serving less densely populated routes.
These contrasts highlight the broad spectrum of business strategies—from global giants like UAL with extensive international and domestic networks, to regionally specialized carriers like SKYW, and innovative low-cost competitors such as JBLU. Together, they illustrate how scale, operational focus, and market segmentation define competition and opportunity within the airline industry.
3.2 Key Findings
The industry-wide data illustrates a definitive trajectory from the severe operational and financial downturn of 2020 towards a sustained, albeit uneven, recovery. Revenue across all three carriers declined significantly during the pandemic’s initial phase, resulting in substantial net losses. Nevertheless, the subsequent years demonstrate a robust rebound in top-line growth, with United Airlines standing out for scale. Profitability has shown a more gradual recovery, hampered by fluctuating fuel and labor costs. The analysis underscores that, although revenue has largely normalized, the quality of earnings and the resilience of balance sheets remain critical differentiators among competitors.
The primary insight from this comparative analysis is that SkyWest (SKYW) has a resilient, strategically advantageous financial profile relative to its peers. While United Airlines’ recovery in operational scale is impressive, SkyWest’s strength is evident in its stable financial structure. This is supported by a Net Debt-to-Equity ratio of approximately 102% in 2024, substantially lower than United Airlines’ ratio, which ranged from about 85% to 177% during the same period, depending on the report and period considered. These ratios confirm that SkyWest’s balance sheet remains healthier and less leveraged than its larger competitor, providing a solid basis for its long-term financial sustainability. Additionally, SkyWest has consistently generated positive free cash flow annually since 2022, a milestone that JetBlue has not achieved. This combination of low leverage and dependable internal cash generation positions SkyWest exceptionally well to navigate forthcoming market uncertainties and to capitalize on emerging opportunities, without being hindered by financial distress.
