Worldwide carriers operating in Japan have resumed adjusted schedules after a massive earthquake, which ripped through the country on March 11, forced the temporary closure of the country’s major airports, according to the Association of Asia Pacific Airlines. Currently, these airlines are focusing on humanitarian efforts and other recovery activities at a time when the stability of Japan’s nuclear power supply and the very real threat of radiation is of growing concern.

“Airlines have been focused on clearing the backlog of disrupted passengers. Domestic flights are now operating according to the normal schedules,” Andrew Herdman, director general of the Association of Asia Pacific Airlines, said in a statement. “Air cargo services are operating normally. Several carriers have also been involved in special humanitarian relief efforts, bringing international supplies and resources to Japan.”
