US airline stocks for 2026 are entering a new phase as the industry continues to recover from the pandemic. Analysts say US airlines are undergoing a ‘structural transformation’, changing how they make money to go beyond simply selling more seats. As a result, airline stocks are valued differently, with investors focusing on premium cabins, loyalty programmes and partnerships.

Delta Air Lines as The Premium Value Pick
Delta is widely seen as one of the strongest US airline stocks in 2026, largely because it appears good value compared with its peers and earns money from more than just ticket sales. The airline’s price-to-earnings (P/E) ratio, a simple way investors measure how expensive a stock is, is projected at around 9.6x for 2026. This suggests investors are paying relatively little for each dollar of profit Delta is expected to make, especially when compared with the wider market.
A major advantage for Delta is its long-standing American Express partnership, which generates high-margin credit card revenue and helps stabilise earnings during fuel price volatility. Delta also consistently ranks among the most reliable US airlines, with strong completion factors reducing the financial impact of delays and cancellations.

United Airlines As The Growth Play
United is positioned as the main growth-focused brand among airline stocks heading into 2026. Its ‘United Next’ strategy, which replaces smaller regional aircraft with larger, more efficient jets, is expected to reduce costs per seat over time. Analysts believe 2026 will be a smoother financial year as United is starting to spend less on new aircraft.
United also operates the largest international network among US airlines, giving it a real advantage as domestic routes become increasingly crowded. According to recent market analysis, United’s shares trade at a trailing P/E ratio of around 11.2x, suggesting investors are willing to pay a higher price today in the hope that the airline’s profits will continue to grow.

Southwest Airlines As A Cautious Hold
Southwest is a more cautious option among US airline stocks for 2026 as the airline goes into year two of its three-year strategic transformation plan. Southwest is modernising its well-known business model by introducing assigned seating and extra-legroom sections. While these changes are expected to bring in more money, the cost of updating the aircraft is likely to keep profits under pressure through 2026.
According to recent financial data, Southwest’s shares remain expensive, with a trailing P/E ratio above 60x, meaning investors are paying a high price in anticipation of a turnaround that has not yet fully happened.

Outlook
For investors or anyone looking at how US airline stocks are performing in 2026, Delta stands out for its balance of value and stability, while United offers more exposure to international routes and premium travel demand. Southwest, meanwhile, remains one to watch, but not an obvious buy just yet. Read more airline stocks here.
