Fuel Price Volatility: Increased Operating Costs:Sudden increases or sustained high prices for jet fuel can significantly impact Delta's profitability and financial performance, as fuel is one of its largest operating expenses.

Economic Sensitivity: Reduced Travel Demand:Economic downturns, recessions, or inflation can decrease discretionary and business travel, leading to lower passenger volumes, reduced revenue per available seat mile (RASM), and pressure on ticket prices.

Public Health Crises: Declining Passenger Volumes:Future pandemics or widespread health concerns can severely restrict travel, leading to government-imposed travel restrictions, customer apprehension, and a sharp decline in passenger demand, similar to the impact of COVID-19.
