As of December 31, 2025, Delta operates a fleet of 1,314 aircraft serving over 200 million customers annually across more than 300 destinations on six continents.

Additional business segments include Delta TechOps, a maintenance, repair and overhaul operation serving aviation customers globally; Delta Vacations, providing customized vacation packages; and cargo operations leveraging the company's global network.
The company operates Monroe Energy, a refinery subsidiary near Philadelphia with capacity to process approximately 200,000 barrels of crude oil daily, supplying jet fuel to Delta's northeastern operations while generating non-jet fuel products.
