Zest Airways, Inc., operated as AirAsia Zest, was a low-cost airline based at the Ninoy Aquino International Airport in Pasay City, Metro Manila in the Philippines. It operated scheduled domestic and international tourist services, mainly feeder services linking Manila and Cebu with 24 domestic destinations in support of the trunk route operations of other airlines. In 2013, the airline became an affiliate of Philippines AirAsia operating their brand separately. Its main base was Ninoy Aquino International Airport, Manila. The airline was founded as Asian Spirit, the first airline in the Philippines to be run as a cooperative. On August 16, 2013, the Civil Aviation Authority of the Philippines, the regulating body of the Government of the Republic of the Philippines for civil aviation, suspended Zest Air flights until further notice because of safety issues. Less than a year after AirAsia and Zest Air’s strategic alliance, the airline was rebranded as AirAsia Zest.
