Delta Air Lines, along with other major carriers like American Airlines and Ryanair, is confronting a significant $11 billion supply chain crisis in 2025. This disruption, stemming from a combination of labor shortages, material scarcities, and geopolitical instability, is causing widespread issues across the travel industry. For Delta, the crisis is leading to delays in fleet modernization, forcing the airline to operate older, less fuel-efficient aircraft for longer periods. The broader consequences for travelers include soaring airfares, increased flight cancellations, and delays as airlines struggle to acquire necessary parts and new aircraft. The issue is also having a ripple effect on the hospitality sector, with major hotel chains like Marriott and Hilton feeling the impact of fluctuating travel demand and higher costs.
