Key Points

GE Aerospace holds a higher multiple based on steady service income prospects, whereas Delta faces pricing as a volatile cyclical business.
Delta Air Lines has broadened its income sources past standard cabin fares, thereby lowering the cyclical nature of its earnings streams.

The valuation gap between GE Aerospace and Delta Air Lines highlights investor perceptions of the commercial aerospace sector. Although this perspective draws from past patterns, the sector has evolved, suggesting the market may undervalue Delta Air Lines at present.

Market Perspective on Commercial Aerospace

Network carriers such as Delta and United Airlines show attractive multiples versus equipment provider GE Aerospace. Notably, GE and its CFM International venture lead in commercial engines that drive airline operations, raising questions about the pricing difference between engine users and suppliers.

Historical Context of the Sector

Traditional airline cyclicality and past shortfalls in returns on invested capital explain the disparity. Carriers often expand capacity aggressively in strong periods, then face downturns with elevated fixed costs that force capacity retention amid recovery hopes. These patterns produced sharp profit swings. Capital markets have viewed the sector cautiously, yet debt remains secured by tangible assets like aircraft.

Consequently, bondholders and suppliers have historically fared well from capital flows into industry assets, while equity investors have struggled. Warren Buffett has publicly criticized airline investments, though Berkshire Hathaway later acquired a Delta position under new leadership.

Reasons for GE Aerospace Premium Valuation

The market assigns GE Aerospace a premium because its expanding engine fleet supports profitable recurring maintenance revenue over decades of use. Delta Air Lines receives a lower rating due to assumptions of earnings volatility tied to traditional cycles.

Attractiveness of Delta Air Lines Shares

While GE Aerospace pricing incorporates optimistic long-term growth views, Delta valuation appears overly conservative. The carrier has successfully diversified beyond heavy reliance on main cabin fares. In the latest quarter, premium cabin revenue reached 6.92 billion dollars, surpassing main cabin revenue of 6.85 billion dollars. Loyalty awards contributed 1.25 billion dollars, and ancillary services added 589 million dollars, leaving under 44 percent of passenger revenue from the main cabin. Other income, including co-branded card payments, surged 50 percent to 3.9 billion dollars.

Overall, Delta no longer depends primarily on cyclical main cabin fares and merits a valuation aligned with the sustained growth outlook applied to GE Aerospace.
