Business History
Harvard Business School has a long tradition of investing in business history, and of asserting its central role in management education. In 1927, the School created the first endowed professorship in the field. It also founded the field’s first journal, the Business History Review. Since the work of Joseph Schumpeter at Harvard's Center for Entrepreneurial History in the 1940s, the School has taken an interdisciplinary and global approach to understanding business history. Today business historians at the School investigate a broad range of themes, including entrepreneurship, innovation, globalization, and environmental sustainability.

In an industry defined by high fixed costs, volatile demand, and thin margins, Delta had become the most profitable U.S. airline, generating roughly half of industry profits while operating about one-fifth of total capacity in 2024. Its 100,000-person workforce—90% frontline employees—supported a global network of 800 destinations across 120 countries, more than 4,000 daily flights, and 200 million annual passengers, while consistently outperforming competitors on financial results, operational reliability, and brand strength, including a 20% premium and industry-leading performance.
That culture faced its greatest test in 2020, when COVID-19 collapsed global air travel by 95% and drove daily losses above $100 million. Unlike its two primary competitors, American and United, Delta avoided involuntary furloughs, instead relying on voluntary measures that reduced its workforce by more than half. As demand rebounded, the airline hired more than 40,000 employees, replacing deep institutional experience with a largely new generation of frontline workers and creating operational and cultural strain. Leaders faced a critical challenge carried across the (A) and (B) cases: how to institutionalize, transmit, and evolve a culture rooted in “service from the heart,” ensuring that new employees could deliver the “Delta Difference” while sustaining competitive advantage in a complex global operation.
This case is designed to be taught in conjunction with “The Spirit of Delta Air Lines: Climbing Through and Beyond COVID-19 (B).” It may also be paired with “Delta Air Lines: Designing the Employee Experience Through a Customer Lens” (326-065) as a broader module on culture and the frontline employee experience.
