In 2025, Delta has surged ahead to surpass other industry giants like Ryanair, United, IAG, IndiGo, Air China, China Southern, Southwest, Singapore, and LATAM to claim the title of the wealthiest airline in the world.

While airlines such as Ryanair and United have strong financials, Delta’s strategic decisions, including its vast fleet and exceptional service, have solidified its position at the top. Delta’s success is not just in its market value but also its ability to maintain profitability year after year. As we dive into how Delta achieved this remarkable feat, we will explore the factors that contributed to surpassing Air China, LATAM, and others to become the global aviation leader.

1. Delta Air Lines: Dominating the Skies of the United States

Why Delta Is #1

Delta has a market value of approximately $37.29 billion, making it the richest airline in the world by market cap. This U.S.-based giant had a remarkable revenue of $61.6 billion in FY2024, and its net income stood strong at $3.5 billion. Delta’s assets are estimated to be worth a massive $75.3 billion, and it employs over 103,000 people worldwide. These figures highlight Delta’s massive financial strength and industry dominance.

Delta’s success can be attributed to its broad network of domestic and international flights, exceptional customer service, and its ability to adapt to changing market conditions. Whether it’s long-haul international travel or domestic flights across the U.S., Delta’s fleet is capable of meeting demand on both ends of the spectrum.
