Zest Air (Manila Ninoy Aquino International) has applied for rights to serve the United Arab Emirates, Saudi Arabia, Australia, New Zealand and Papua New Guinea. Industry analysts believe the development is part of a new Zest strategy to go head to head with rivals Cebu Pacific Air (5J, Manila Ninoy Aquino International) and Philippine Airlines (PR, Manila Ninoy Aquino International) internationally who themselves will be launching flights to Dubai International in October and three new Australian destinations in June respectively. However, while the prospect of new international destinations beckons, reports out of Manila state the Civil Aeronautics Board of the Philippines (CAB) has warned that Zest Air and partner, AirAsia Philippines (Manila Ninoy Aquino International), may face stringent penalties after it was found that Air Asia's website had been used for ticket sales and reservations for both airlines; a move the CAB had not sanctioned. Under Filipino law, in order to protect public interests, the nature of the relationship between airlines must necessarily be disclosed with any marketing agreement requiring CAB approval. Zest and Air Asia officially completed their strategic alliance agreement on May 10, 2013.
