Zest Air was a low-cost carrier based in the Philippines that operated domestic routes connecting Manila with various provincial destinations across the archipelago. The airline positioned itself as a budget alternative for Filipino travelers seeking affordable air travel. Founded in the mid-2000s, Zest Air operated from Ninoy Aquino International Airport in Manila and served key domestic destinations including Cebu, Davao, and other provincial cities. The airline competed in a growing low-cost market alongside AirAsia Philippines and Cebu Pacific. In 2013, Zest Air entered into a partnership and eventual merger with AirAsia Philippines, ceasing operations under its own brand. The airline had faced financial difficulties and regulatory challenges before the consolidation with AirAsia Philippines effectively absorbed its operations.
