Delta Air Lines, along with other major carriers such as American Airlines, Ryanair, and Southwest Airlines, is confronting a significant $11 billion supply chain crisis in 2025, which is causing widespread disruptions across the global tourism and hospitality sectors. This crisis, stemming from a combination of labor shortages, material scarcities, and geopolitical instability, has resulted in increased airfares, flight cancellations, and delays. For Delta, the disruptions are causing delays in fleet modernization, forcing the airline to operate older, less fuel-efficient aircraft for longer periods, which in turn drives up operational costs and ticket prices for consumers. The airline has had to reduce the frequency of flights to popular European and Asian destinations as a direct consequence of these supply chain issues. The crisis is also having a significant ripple effect on the hospitality industry, with major hotel chains like Marriott, Hilton, and Accor experiencing pressure from the resulting travel disruptions.
