Korean Air and Delta Air Lines have partnered with Habitat for Humanity to repair and renovate homes in Calauan, a location in the Philippines that was hit by Typhoon Ondoy in 2009. The project involved the two airlines working together on minor carpentry work, window and door repairs, and repainting three homes. KLM has worked with Habitat for Humanity since 2013 and Delta Air Lines has been involved in building or rehabilitating over 270 homes since 1995 through its partnership with the non-profit. The two airlines have worked on several joint community service projects since forming a joint venture in 2018.
