Founded in 1924, Delta Air Lines, Inc. (DAL) has spent more than a century turning the skies into its playground. Today, it ranks among the world's largest airlines, carrying passengers and cargo across a sprawling domestic and international network. Commanding a market cap of nearly $57 billion, the carrier operates a fleet of more than 1,300 aircraft.
Alongside its airline operations, the Atlanta, Georgia-based giant pulls in revenue from aircraft maintenance, repair, and overhaul services for third parties, vacation package offerings, and refinery operations that help support its fuel supply requirements.
