Every year, Delta flies more than 170 million people on board its airplanes. But it’s not just the work its employees do to connect customers around the world that matters. Delta employees can someties make the biggest impact by serving the communities where they live and work.

Delta, the Delta Air Lines Foundation and its employees contribute thousands of volunteer hours and millions of dollars to a host of civic causes through its arts and culture, education, environment, health and wellness, and military and veteran efforts.

Whether building houses for Habitat for Humanity in Argentina, constructing a playground with KaBOOM! in Seattle, donating blood to the American Red Cross in Atlanta or educating students through Junior Achievement in New York, Delta employees gave back again and again in 2015.
